Terms of service

Last updated: 4 November 2026

1. Service overview

Unopost ("the Service", "we", "us" or "our") provides an online postal mail service operated by AWS, CYY & Co. Pty Ltd (ACN 686 116 245) as Trustee for Mumu, Lulu & Co. (ABN 54 837 123 965) via unopost.com.au. The Service enables users ("you" or "the Customer") to upload digital documents, which we print, place in an envelope and lodge with Australia Post for delivery to an address in Australia. The Service is available on unopost.com.au, through our x402 API and, for Business Accounts, through the business portal and the Business API, and is operated from Melbourne, Australia. Card and digital wallet payments on our website are processed by Square AU Pty Ltd (ABN 38 167 106 176).

You can also ask an AI assistant, such as Claude or ChatGPT, to prepare a Letter through our connector at https://unopost.com.au/api/mcp. The assistant gives us your document and the addresses and options you give it. A Letter prepared this way is ordered only when you review it and pay for it on our website, and these Terms apply to it as to any other Letter ordered on our website. We are not responsible for what an AI assistant gives us or tells you; check the preview, addresses and price before you pay.

We also offer a free PDF merger at https://unopost.com.au/merge-pdf, which joins and reorders PDFs and photos in your browser. It is part of the Service and these Terms apply to it, but we charge nothing for it and do not receive the files you add unless you choose to post the merged PDF as a Letter. You are responsible for checking the merged PDF before you rely on it or send it.

We also offer a free postage calculator at https://unopost.com.au/postage-calculator, which compares the prices Australia Post publishes for its tracked prepaid envelopes with our prices for printing and posting a Letter. It is part of the Service and these Terms apply to it, but we charge nothing for it. The Australia Post prices it shows are taken from the Australia Post guides it names, as at the dates it states; they are general information only, Australia Post may change them at any time, and the price Australia Post charges when you post is the one that applies. Our prices it shows are those in effect when you use it; the price you pay for a Letter is the one shown when you place your order.

We also offer free letter templates at https://unopost.com.au/letter-templates, which write a letter in your browser from the answers you give. They are part of the Service and these Terms apply to them, but we charge nothing for them. The templates and the guidance on their pages are general information only and are not legal advice: we are not a law firm, we do not act for you, and we do not know your circumstances. You are responsible for what your letter says, for checking that it is accurate and suits your situation, and for the consequences of sending it. We do not receive your answers or your letter unless you choose to have us post it as a Letter.

An AI assistant may tell us that it is preparing a Letter for a business, such as one writing to its own clients, and give us that business's email address. We do not check what it tells us. Before you pay, our website shows you the business's name as the assistant gave it and the email address. If you pay for the Letter, you agree that we send that business a copy of each email we send you about the Letter, including its tracking number and delivery status. If you do not agree, do not pay for the Letter; you can ask the business about it, or order a Letter yourself on our website.

Unopost is not Australia Post and is not a postal service provider. Printing and enveloping are carried out by us, and letters are carried and delivered by Australia Post under its own terms and conditions (https://auspost.com.au/terms-conditions).

The liability of the Trustee is limited to the assets of the trust known as Mumu, Lulu & Co. from time to time. No party may seek to recover from the Trustee personally or from the directors of the Trustee in their personal capacity.

3. Acceptance of terms

By accessing, browsing or using the Service in any manner, you acknowledge that you have read, understood and agree to be bound by these Terms. Our Privacy Policy (https://unopost.com.au/privacy) explains how we handle personal information. It does not form part of these Terms.

If you do not agree to these Terms, you must not access or use the Service. Each use of the Service constitutes a renewed acceptance of these Terms as they exist at the time of use.

4. Eligibility

The Service is available to individuals who are at least 18 years of age or the age of majority in their jurisdiction, whichever is greater. By using the Service, you represent and warrant that you meet this requirement and have the legal capacity to enter into a binding agreement.

The Service is intended for lawful business and personal use. You must not use the Service on behalf of any entity unless you are duly authorised to bind that entity to these Terms.

5. Service description and delivery

The Service operates on a self-service, pay-per-letter basis. No account registration, subscription or ongoing commitment is required, except that Letters paid for with Business Credit require a Business Account (see Section 7).

To use the Service, you must: (a) upload a document in a supported file format (see Section 6); (b) enter a valid Australian address for the recipient; (c) enter your name and your address, which we print on the envelope as the return address; (d) choose a Service Level, any printing options and, for Express Post, the envelope; (e) enter your email address; and (f) complete payment. Before paying, you will be shown a Preview of your Letter, whatever its file format. Your Letter is printed as shown in the Preview.

On our website, you may send the same document to several recipients in a Multi-Recipient Order by entering or pasting their addresses. Each recipient is sent a separate Letter, printed from the same document with the same Service Level and options, in its own envelope and with its own tracking number. These Terms apply to each of those Letters as if it had been ordered on its own, and you must check each recipient's address before you pay.

The return address must be your own name and an address at which you receive mail or, if you send for a business, that business's name and address. You must not give another person's name or address, or a false one, as the return address. Where your browser's timezone indicates that you are outside Australia, the Website may select a country for the return address in advance; that selection is a convenience only, and you remain responsible for ensuring that the return address, including its country, is correct. A Business Account's return address is printed on every Letter sent from it, unless a different return address is given for a particular send, in which case that address is printed on the Letters in that send only and must meet the same requirements. Australia Post returns a Letter it cannot deliver to that address, and we do not receive or forward returned mail.

Letters paid for by 2:30pm Melbourne time on a Business Day are Despatched that Business Day. Letters paid for after that time, or on a day that is not a Business Day, are Despatched no later than the next Business Day. We may Despatch a Letter earlier than this Section requires. If something outside our control prevents us from lodging your Letter on time, we will email you. If we do not Despatch your Letter by 11:59pm Melbourne time on the Business Day by which this Section says it is Despatched, the despatch guarantee in Section 9 applies.

Delivery times are set by Australia Post, not by us (https://auspost.com.au/personal/sending/delivery-speeds-and-coverage). Express Post usually delivers the next business day within the Express Post network and regular post usually delivers in 3 to 7 business days, but we do not guarantee any delivery date or time. If your Letter must arrive by a deadline, you are responsible for choosing an appropriate Service Level and allowing enough time. Expect Australia Post to take longer around public holidays, including one in the recipient's state or territory that is not a public holiday in Melbourne.

Our Service is to print, envelope and Despatch your Letter, and it is complete once your Letter is lodged with Australia Post. From that point, carriage and delivery are provided by Australia Post under its own terms and conditions, and we do not control them. We do not guarantee that a Letter will be delivered, delivered on time, delivered in good condition, or delivered to the intended recipient, and we are not responsible for any Letter that is lost, delayed, damaged, misdelivered or returned after it is Despatched. Any delivery guarantee, such as an Express Post guarantee, is given by Australia Post and not by us.

Every Letter sent by regular post or Express Post is tracked at no additional charge. We will email you the tracking number shortly after your Letter is Despatched and, if we later correct it, the corrected tracking number. Where a Letter is sent with signature on delivery, whether a signature is obtained, and what happens if nobody is available to sign, is determined by Australia Post. Australia Post usually captures a signature when it delivers a Letter sent with signature on delivery, but it does not always do so. A Letter may be recorded as delivered without a signature, or with a signature that is incomplete or illegible, including where it is left in a letterbox or safe place, delivered to a parcel locker or post office, or signed for by someone other than the recipient. We do not guarantee that a signature will be obtained or will appear in Australia Post's tracking records, and Australia Post's record of delivery, with or without a signature, is the only record of delivery we can provide. If you need proof that a document was received, for example to serve it, you should not rely on signature on delivery alone. Australia Post's tracking record shows the service each Letter was lodged with, and is evidence that we sent it with signature on delivery as you paid for, whether or not a signature is obtained. Because this is outside our control, we do not refund any part of the price of a Letter where a signature is not obtained or not recorded.

We do not check the accuracy, completeness or legal effect of your Content, or that the address is correct for your intended recipient. If we notice a problem with your Letter, your order or your payment before the Letter is Despatched, including anything unusual that we ask you to confirm, we will hold the Letter and contact you by email. If the problem is not resolved, or you do not confirm, within 2 Business Days, we may cancel the Letter in accordance with Section 9.

Regular post is always folded, so it only takes documents of up to 12 pages. If your document is longer, we cannot send it by regular post, and you will need to choose Express Post, which costs more. We will tell you before you pay. We may also adjust how your Letter is printed where required by these Terms or our printing requirements: in particular, we check for statutory declarations and print them single-sided, although we cannot always detect one in a scan or a photo, so leave double-sided printing off if you are sending an official form. The price of your Letter does not change when we make these adjustments.

Processing begins immediately upon payment confirmation, so there is no cooling-off period once you have paid. This does not affect your rights under the Australian Consumer Law.

By providing your email address and completing payment, you consent to receiving transactional email communications related to your Letter, including Despatch and delivery notifications, tracking numbers, problem notifications and refund notices. You must provide an email address that you control and can access. We may, but are not obliged to, notify you by email when Australia Post's tracking records show that your Letter has been delivered, and that email may invite your feedback on the Service. Giving feedback is optional, and we will not publish it as a testimonial unless you tell us that we may. We may likewise, but are not obliged to, notify you by email when those records show that your Letter is being held for collection. We may also, but are not obliged to, notify you by email when those records show that your Letter has been delayed or could not be delivered, and ask you to contact Australia Post about it. Any such notification repeats Australia Post's record as at the time we viewed it and is not a confirmation, representation or warranty by us that the Letter was delivered. If we photograph your Letter's envelope when we post it, we may attach that photo, which shows the recipient's name and address, to the email that gives you its tracking number. It records how the envelope was addressed, not its posting or delivery, which Australia Post's tracking records show. We keep the size and a SHA-256 digest of that photo after we delete it, so that we can confirm whether a copy is the photo we took.

We may change the technology, systems, software and service providers we use to provide the Service at any time, as long as the change does not materially reduce the Service you have paid for. We do not update these Terms each time we do, unless the change affects your rights or obligations under them. We list our current service providers in Section 7 of our Privacy Policy, and describe our security measures in Section 11 of it (https://unopost.com.au/privacy).

6. Service limitations

The following limitations apply to each Letter:

  • Maximum file size: 50 MB per upload
  • Maximum page count: 80 A4 pages by Express Post posted flat, or 12 pages by regular post, registered post or folded Express Post, counted after your document is laid out for printing
  • Supported file formats: PDF, DOC, DOCX, JPG, JPEG, PNG, HEIC and HEIF. HEIC and HEIF photos are converted to JPEG in your browser before they are uploaded
  • Supported destinations: street addresses and PO Boxes in Australia, including every state and territory, by regular post, registered post or Express Post. We do not post to addresses outside Australia. We do not collect the recipient's telephone number
  • Paper format: all documents are printed on standard 80gsm A4 paper, single-sided unless you choose double-sided printing, in which case pages are always printed to be turned on the long edge, and in colour as uploaded unless you choose black and white printing. If you choose stapling, which is available for documents of up to 12 pages, the pages are stapled once in the top-left corner. If you choose a paper clip instead, which is available for documents of up to 20 pages, the pages are held together with one paper clip in the top-left corner. You cannot choose both stapling and a paper clip. Pages are scaled to fit A4, except that a page much longer than A4 may be printed across several A4 pages, each of which counts towards the page count. With Express Post, pages past the first 12 are charged at the per-page rate. With regular post, extra pages may take the document over the 12-page limit, in which case it must be sent by Express Post
  • Envelope: regular post Letters are always folded in thirds to fit a DL or larger envelope that fits most letterboxes, so regular post takes Letters of up to 12 pages. Registered post Letters are folded in the same way. Express Post Letters go flat in a B4 envelope unless, when placing your order, you choose to have the Letter folded in half into a C5 envelope at no extra cost, which is available for Letters of up to 20 pages. We take care to post flat Letters uncreased, but we are not responsible for creasing or bending in transit, including where a Letter is folded to fit a letterbox. If you need a Letter handed over rather than left in a letterbox, add signature on delivery
  • Signature on delivery: available as an option with Express Post, at the price shown at checkout. Regular post with signature on delivery is registered post

We may scan uploaded files for viruses and other malicious code, and we reject any file we detect as malicious or cannot safely process. Macros and other active content in Word documents are never run. Word documents are converted to PDF before printing, and their layout may differ from how they appear in your word processor. The Preview shows the Letter as it will be printed.

We reserve the right to reject or cancel any Letter that exceeds these limitations, that we cannot print legibly, or that we reasonably determine may breach Section 10 or cause harm to our systems or third-party infrastructure. If we reject or cancel a Letter you have paid for, we will refund it in full as described in Section 9.

7. Pricing and payment

Each Service Level has a flat rate per Letter. Express Post covers 20 pages, whether posted flat in a B4 envelope or folded into a C5 envelope, with a per-page charge for each page after that, up to 80 pages. Regular post is a flat rate for a Letter of up to 12 pages, with no per-page charge. Tracking is included with every Service Level, and colour printing, double-sided printing, black and white printing and stapling are included with every Service Level, at no additional charge. Signature on delivery costs extra. Registered post is priced as regular post plus signature on delivery. Current prices are displayed on our Pricing page (https://unopost.com.au/pricing) and at checkout. A price shown as "from", or marked with an asterisk (*), is the lowest price for that Service Level; the price of your Letter depends on the envelope, page count and options you choose, and is shown to you before you confirm payment. All prices are in Australian Dollars and include Australian Goods and Services Tax (GST).

The total cost of a Letter is calculated after your document is converted and the actual page count is determined. The final cost is shown to you, on our website or at checkout, before you confirm payment. Prices may be updated from time to time. The price applicable to your Letter is the price displayed at the time of payment. The Fees for a Multi-Recipient Order are the Fees for one Letter multiplied by the number of recipients, as calculated by us when you pay, and are paid in a single payment.

We are registered for GST. Fees include GST. For each card or digital wallet payment for a Letter, the receipt Square issues on our behalf, which our order confirmation email links to, is your tax invoice. For each purchase of Business Credit, we email our own receipt, as an attached PDF, to the Business Account's billing email address and to each owner of the Business Account. No GST is charged on a purchase of Business Credit: the GST in a Letter's Fees is counted when Business Credit pays for it, and a tax invoice for the Letters sent from a Business Account between any two dates can be downloaded from the business portal on request.

Currency conversion, if applicable, is performed by your card issuer at their prevailing exchange rate and is outside our control. Your card issuer may charge additional fees for international transactions. Where the website shows a price in a currency other than Australian Dollars, it is an estimate only, at an exchange rate published on the date shown, and is not the amount you are charged.

Our Payment Processor is Square AU Pty Ltd (ABN 38 167 106 176) ("Square"), which provides the payment processing services for card and digital wallet payments on our website. By placing an order and using Square to process payments, you agree to be bound by Square's General Terms of Service (https://squareup.com/au/en/legal/general/ua) and Buyer Privacy Notice (https://squareup.com/au/en/legal/general/buyer-privacy), which may be modified by Square from time to time. You consent to Square's collection and use of your information as described in their Buyer Privacy Notice, and you authorise us to share transaction information related to your use of the payment processing services with Square. You enter your card details into Square's payment form on our website, which sends them directly to Square. Square issues the tax invoice for your payment for a Letter, and our order confirmation email links to it. We do not store, access or process your full card details at any time. Where a card is saved to a Business Account, Square stores it, and we keep only Square's reference to it and the card's brand, last four digits and expiry date.

We may give you a discount code, for example to thank you or to make up for a problem with a Letter. A code takes the amount or percentage it states off the Fees for a Letter ordered on our website and paid for by card, and is entered before you pay. It applies to one Letter at a time, can be used until the end of its expiry date, Melbourne time, and cannot be added to a Letter that has been paid for. A code cannot bring the Fees for a Letter below $1.00, cannot be used for a Letter paid for with Business Credit or through the API, and has no cash value. We may limit the number of Letters a code can be used for, and once it has been used for that many Letters it no longer works. We may withdraw a code at any time before you pay. If a Letter paid for with a code is refunded, we refund the amount you paid.

Business Accounts are available only to businesses that carry on business in Australia and hold a current Australian Business Number (ABN), and are opened only with our approval. You apply using the application form on our website, with an email address at your business's own domain; we do not accept free webmail or internet provider email addresses. We check the ABN you give us against the Australian Business Register, and we may ask you to verify it or your authority to act for the business. We aim to contact you about your application within 1 Business Day of receiving it, and we may decline to open a Business Account.

Opening a Business Account is free. A business with a Business Account prepays for Letters by buying credit ("Business Credit"): at least $10 for each purchase, including the first. Business Credit is bought by card in the business portal or, where we agree in writing, by bank transfer or another payment method, in which case we add the Business Credit to the Business Account once the payment has cleared. We may also add Business Credit to a Business Account at our discretion. Business Credit we add is subject to the same terms as Business Credit bought by card. Business Credit we add without payment, however, has no refund value and is used before Business Credit the business has paid for, as our Business Agreement provides. Unless an owner or administrator turns the alert off, we email the billing email address when a Letter takes the Business Credit below the amount set for the low credit alert. Unless that alert is turned off, we also email that address, no more than once in any 24 hours, when a Letter cannot be sent through the Business API because the Business Credit is less than its price. Business Credit does not expire, and unused Business Credit is refunded on request as our Business Agreement provides. An owner or administrator may save a card to the Business Account and turn on automatic top-up. By turning on automatic top-up, the business authorises us to charge the saved card the top-up amount it has chosen each time a Letter leaves its Business Credit below the threshold it has chosen, until an owner or administrator turns automatic top-up off or removes the card. If a top-up charge is declined, we turn automatic top-up off and email the billing email address, and we do not try the card again until automatic top-up is turned back on. Letters from a Business Account go in Australia Post prepaid envelopes, with no custom or branded envelopes. When a Letter or Bulk Send is sent from the business portal, we count the pages of the documents uploaded for it, including any document a team member chooses from those stored in the Business Account, which is copied into the Letter and deduct the price of every Letter in it from the Business Credit at once, and it is sent only if the Business Credit covers every Letter. An owner or administrator may require that Letters sent by team members who are not owners or administrators be approved before they are sent. While that setting is on, a Letter or Bulk Send such a team member submits is not accepted for printing or posting, and no Business Credit is deducted for it, until an owner or administrator approves it. On approval, its price is calculated at the business rates that apply at that time and deducted from the Business Credit, and it is sent only if the Business Credit covers every Letter in it. Until it is approved, an owner or administrator may reject it and the team member who submitted it may withdraw it. A Letter or Bulk Send that is not approved within 7 days after it is submitted lapses and is not sent. The business is responsible for each Letter that an owner or administrator approves as if the owner or administrator had sent it. We show each Letter's tracking number in the business portal when it is Despatched and, unless an owner or administrator turns these emails off, email the billing email address the tracking numbers once every Letter sent together has been Despatched or cancelled. We also show each Letter in the business portal as delivered when we see that Australia Post's tracking records its delivery, as our Business Agreement provides. Business Accounts, Business Credit, business rates, the Business API, team members and documents stored in a Business Account are governed by our Business Agreement and, for the Business API, by the documentation and API Terms published at unopost.com.au/business/api, which an owner or administrator must accept on behalf of the business before the Business Account can be used. When the Business Agreement is accepted, we email a copy of it as accepted, in PDF, to the person who accepted it and to each owner of the Business Account. For a Business Account and the Letters sent from it, the Business Agreement prevails over these Terms, and the provisions of these Terms that the Business Agreement says do not apply to a Business Account do not apply to it. A Business Account can be used to post Letters within Australia only. A Letter sent by registered post from a Business Account may be up to 20 pages.

Once a business has sent 20 Letters from its Business Account in a calendar month, Melbourne time, the Fees for each further Letter it sends from it in that month are reduced by $2, except for a Letter sent by regular post without signature on delivery, which is counted but not reduced. A Letter is counted when it is paid for from Business Credit, whether it is sent in the business portal or through the Business API, and is no longer counted if it is cancelled. For a Letter sent through the Business API, the reduction is applied when the Letter is sent, and the price shown before then does not include it. We may change or withdraw this discount at any time, which does not affect a Letter already sent.

Each person on a Business Account signs in with a one-time code we email to them. Once the business has bought or been given Business Credit, each of them must also set up an authenticator app and enter a code from it each time they sign in, and may put setting one up off no more than twice. Once the business has stored a document in the business portal, it cannot be put off. The business is responsible for keeping its team members' email accounts and authenticator apps secure, and for promptly asking us, or an owner or administrator, to reset the authenticator of a team member who loses it or leaves. Before we reset an authenticator, we may ask the business to verify the request.

Letters ordered through the API are priced and paid for in USDC rather than by card, as described in Section 8.

8. Letters ordered through the API

The Service is also available through our x402 API, documented at https://unopost.com.au/x402. These Terms apply to a Letter ordered through the API in the same way as to a Letter ordered on the website, and the following additional terms apply.

No account or API key is required to use the API. You are responsible for every Letter created and paid for from your wallet, including a Letter created by software or by an autonomous agent acting for you. Where you use the API to send Letters for another person, or on another person's instructions, you are responsible for their Content as if it were your own, and you warrant that you have that person's authority and the right to send it. Section 10 applies to every Letter sent through the API.

Fees for a Letter ordered through the API are payable in USDC on the Base network, in the amount and to the address shown in the API's payment response. Prices quoted in USDC are GST-inclusive prices for a supply made in Australia. Where an amount must be expressed in Australian Dollars for GST purposes, we convert the amount paid at the exchange rate applying on the date of payment. You are responsible for holding a wallet with enough USDC to pay for your Letter; we pay the network fee (gas).

A quote lasts 7 days from the time a Letter becomes ready to send. If a quote expires unpaid, the Letter is not printed or Despatched, and your uploaded document is deleted in accordance with Section 13.

Payments made through the API are settled on a public blockchain and cannot be reversed by us. Where a refund is payable under Section 9, we pay it in USDC to the wallet address the payment came from, in the same amount of USDC that was paid. We are not responsible for any change in the value of USDC between payment and refund, for a payment made from a wallet you do not control, or for a refund that cannot be received at the paying address.

We do not send email about Letters ordered through the API. The Letter's status, which you retrieve from the API, is the only record of its progress, and you are responsible for checking it. The Preview is provided as a print-ready PDF at the previewUrl in the API's response, and you are responsible for checking it before you pay. If you need a tax invoice for a Letter ordered through the API, email us at support@unopost.com.au with the jobId.

The API is provided as it stands. We may change, limit, suspend or withdraw the API, any endpoint and its prices at any time. The price that applies to your Letter is the price in the payment response you pay against. Where we have agreed business pricing with you and issued you a bizKey, the prices for Letters sent with that key are the prices we have agreed with you and shown in the payment response, in place of our list prices. We issue a bizKey only on a separate written application, at our discretion, and on the terms we give with it, which apply to Letters ordered with that key together with these Terms. A bizKey cannot be used with Business Credit, and Letters ordered through the API are not paid for from a Business Account. You must keep a bizKey secret. You are responsible for every Letter ordered and every payment made with your bizKey, whether or not you authorised it, and we are not liable for any loss arising from its use, except to the extent the use results from unauthorised access to our systems, disclosure of the key by us or our service providers, our failure to take reasonable security measures or an error in our systems, or occurs more than 1 Business Day after you tell us at support@unopost.com.au that the key has been disclosed or misused. We may suspend, revoke or replace a bizKey at any time, including if we reasonably suspect it has been disclosed or misused.

9. Cancellations and refunds

You may cancel a Letter you have paid for by card on our website until we start to print it, using the option on its status page, and we will refund the full amount you paid for it, without deduction, to your original payment method within 5 Business Days. We start to print a Letter when we first open its print file, usually on the day it is paid for. Once we have started to print your Letter, it can no longer be cancelled through our website. If you contact us at support@unopost.com.au after we have started to print your Letter but before it has been Despatched, we will try to stop it, but we cannot guarantee that we will. If we stop it, we may, at our discretion, refund the amount you paid for it less $0.30 for each page we have printed and a manual handling fee of $5. A Letter cannot be cancelled once it has been Despatched. A Letter paid for through the API cannot be cancelled through our website. A Letter sent from a Business Account can be cancelled free of charge until we start to print it, as our Business Agreement provides. Once a Multi-Recipient Order is paid for, none of its Letters can be cancelled through our website. If you contact us at support@unopost.com.au before a Letter in it is Despatched, we will try to stop it, but we cannot guarantee that we will. If we stop it, we may, at our discretion, refund part of the amount you paid for it, to reflect the manual handling involved. The rest of this Section, including our refunds where we refuse, cancel or do not Despatch a Letter on time, applies to each of its Letters.

Incorrect address: If you tell us at support@unopost.com.au that you entered an incorrect address before your Letter is Despatched, we will use reasonable efforts to correct it and will let you know by email whether we were able to. Once your Letter is Despatched, we cannot change its address, and a Letter sent to an incorrect address is not refunded, as set out below.

Right to refuse service: We reserve the right, at our sole discretion, to refuse to accept, or to cancel, any order or Letter at any time before it is Despatched, for any reason or no reason, including under Sections 6 and 10. Where we refuse or cancel a Letter after you have paid for it, we will refund the full amount you paid for it, without deduction, as described in the following paragraph. To the extent permitted by law, that full refund is our entire liability, and your sole remedy, for our refusal or cancellation.

If we are unable to print or Despatch your Letter after you have paid for it, including where a problem we notify you of under Section 5 is not resolved, we will cancel the Letter and refund the full amount you paid for it. We will process the refund to your original payment method within 5 Business Days of cancelling the Letter. Refunds typically appear on your statement within a further 3 to 5 business days, depending on your card issuer. We will notify you by email when a refund is issued. A Letter paid for through the API is refunded in USDC as described in Section 8, and its status changes to failed. A Letter paid for with Business Credit is refunded by restoring its Business Credit, as our Business Agreement provides, and is shown in the business portal as not posted.

Despatch guarantee: If we do not Despatch your Letter by 11:59pm Melbourne time on the Business Day by which Section 5 says it is Despatched (the day you paid for it, if you paid by 2:30pm Melbourne time on a Business Day, and otherwise the next Business Day), we will refund the full amount you paid for it, without deduction and without you needing to ask. Whether and when a Letter was Despatched is shown by Australia Post's lodgement receipt or tracking record. We will still Despatch the Letter unless, before it is Despatched, you ask us to cancel it. The refund is processed as described in the previous paragraph. This guarantee does not apply while we hold a Letter under Section 5 because of a problem we have notified you of, or to a Letter we refuse or cancel, which is refunded under this Section in any event. It concerns only when we Despatch your Letter and is not a guarantee of any delivery date or time, which is set by Australia Post. For a Letter sent from a Business Account, this guarantee and the Despatch times in Section 5 apply as our Business Agreement provides: where a business sends more than 100 Letters in a day, they apply only to the first 100, and they do not run while a Letter is held or is being checked by hand.

We generally cannot refund a Letter in the following circumstances, although this never limits your rights under the Australian Consumer Law:

  • The address you entered was incorrect, incomplete or out of date, or you entered the wrong recipient, including where the Letter is delivered to that address, returned to sender, or lost as a result
  • The recipient has moved, refuses the Letter, is not available to sign for it, or does not collect it from a post office. This includes where you paid for signature on delivery and a signature is not obtained or not recorded
  • The file you uploaded was corrupted, damaged, incomplete, blank, password-protected, low-resolution or otherwise unreadable, and the Letter was printed as shown in the Preview
  • You uploaded the wrong document, or a version of your document with errors, missing signatures or missing pages
  • The layout of a converted Word document differs from your word processor, and the Letter was printed as shown in the Preview
  • The Letter is creased, bent or damaged in transit, including when it is left in a letterbox without signature on delivery
  • Australia Post takes longer to deliver the Letter than its usual delivery times, or the Letter does not arrive in time for a deadline
  • The recipient does not accept a printed copy in place of an original or a document with an original signature
  • You change your mind after we have started to print the Letter ("sender's remorse"), except as set out in the first paragraph of this Section

Once a Letter is Despatched, it is in the care of Australia Post, and we are not obliged to refund or resend a Letter that is lost, delayed, damaged or misdelivered in the post. Any enquiry or claim about such a Letter must be lodged by you directly with Australia Post, using the tracking number we provide (https://auspost.com.au/mypost/track). Any refund by us in these circumstances is at our discretion.

Billing disputes must be raised within 30 calendar days of the payment date by contacting us at support@unopost.com.au with your Letter's reference. We will investigate all disputes in good faith and respond within 10 Business Days.

Chargebacks: If you believe a charge is incorrect, we ask that you contact us at support@unopost.com.au before initiating a chargeback (payment dispute) with your card issuer, so that we can look into it and put it right more quickly. Nothing in this paragraph prevents you from disputing a charge with your card issuer, or affects your rights under the Australian Consumer Law.

Nothing in this Section limits your rights under the Australian Consumer Law or any applicable consumer protection legislation, including your right to a remedy where a service fails to meet a consumer guarantee, or your right to lodge a complaint with the Australian Competition and Consumer Commission (https://www.accc.gov.au) or a state or territory consumer affairs agency.

10. Acceptable use policy

You agree to use the Service only for lawful purposes and in accordance with these Terms. Without limitation, you must not use the Service to send:

  • Unsolicited advertising or promotional material in bulk (junk mail)
  • Content that is illegal, defamatory, obscene, threatening, abusive, harassing or otherwise objectionable, or that is intended to intimidate or stalk the recipient
  • Content that infringes any third party's intellectual property rights, privacy rights or other legal rights
  • Documents that impersonate any person, business, court, government agency or other entity, or that falsely appear to be issued by them
  • Scams, fraudulent demands or misleading notices, including debt collection letters that breach applicable law
  • Content that breaches any court order, intervention order or similar restriction on contacting the recipient
  • Content intended to commit, assist or conceal a criminal offence, including threats, extortion, blackmail, fraud and identity theft
  • A Letter with a false sender name or a return address that is not yours, as described in Section 5

You must not attempt to gain unauthorised access to our systems, interfere with the operation of the Service, or circumvent any security measures.

We reserve the right to refuse or cancel any Letter, and to suspend or terminate your access to the Service, immediately and without notice if we reasonably believe you have violated this Acceptable Use Policy. If we cancel a Letter you have paid for under this Section, we will refund the full amount you paid for it as described in Section 9. Suspending or terminating your access does not affect any Letter that has already been Despatched. We may report suspected criminal activity to the police or another authority and give them the records we hold about the Letter and who sent it, as our Privacy Policy describes.

11. Customer responsibilities and warranties

You represent and warrant that:

  • All information you provide, including the recipient's name and address, your return address and your email address, is accurate and complete
  • The document you upload is the final, complete version you intend to send, including any required signatures
  • You have the legal right and authority to send the Content you upload
  • Your use of the Service complies with all applicable laws and regulations
  • The Content does not contain any viruses, malware or other harmful code

You are solely responsible for checking the recipient's address and your Preview before paying. Our address checks confirm only that an Australian address is in a valid Australian format and that its postcode belongs to its state. They do not confirm that the address exists or that your intended recipient receives mail there. Addresses suggested as you type come from a third-party map data source, which may be incomplete or out of date, and do not include any unit or level unless you add it; you must check a suggested address before paying. We bear no responsibility for Letters sent to incorrect addresses due to customer error.

Letters returned to sender by Australia Post are returned to the return address you provide. We do not receive, hold or forward returned mail.

You are responsible for confirming that a printed copy will meet your needs, including whether the recipient requires an original document, an original signature, or a particular method of service. Tracking and signature on delivery records are provided by Australia Post, and we make no representation that they will be accepted as proof of posting, delivery or service for any legal purpose.

12. Intellectual property

All intellectual property rights in the Service, including but not limited to the website design, user interface, software, logos, trademarks and documentation, are owned by or licensed to Unopost and are protected by applicable intellectual property laws.

You retain ownership of all Content you upload. By uploading Content, you grant us a limited, temporary licence to process, convert, review, print and post that Content, and to share it with our service providers, solely for the purpose of fulfilling your Letter. This licence terminates automatically upon deletion of the Content in accordance with Section 13.

13. Document handling and data security

We take the security and confidentiality of your documents seriously. The following practices apply:

  • All documents are encrypted in transit using TLS, and encrypted at rest by our cloud infrastructure provider
  • Uploaded documents, including documents uploaded to a Business Account, are stored in secure cloud infrastructure (Amazon Web Services, Sydney region) only for conversion, printing and posting
  • The recipient's name and address and your return address, as they appear on the envelope, are shared with Australia Post solely for the purpose of delivering your Letter
  • Documents are converted automatically by our systems. Letters are then printed, placed in envelopes and lodged with Australia Post by hand, by us, so the person at Unopost who prints and posts your Letter may see your Content while doing so. They handle it only for that purpose, and do not copy or keep it. Otherwise, no one at Unopost reads your Content unless required by law, legal process, or to resolve a problem with your Letter, a billing dispute, a support request you have initiated or a security concern
  • Your uploaded document and its print-ready copy are permanently deleted once your Letter is Despatched. We do not keep a copy after that, so a Despatched Letter cannot be reprinted or posted again. Documents for Letters that are not paid for or cannot be posted are deleted after 14 days. We keep only the size and a SHA-256 digest of each file you upload and of the print-ready copy, with the record of your Letter. A digest identifies a file but cannot be turned back into it, so we cannot read or reprint your Letter from it. If there is a dispute about what was posted, we can use it to confirm whether a copy that you or anyone else produces is the file you sent. You should keep a copy of your document as it was sent, because a copy that has been changed will not match
  • We keep a record of each Letter, including the recipient's name and address, your return address and email address and, for a Letter sent outside Australia before we stopped posting outside Australia, your telephone number if it was sent by International Express and the recipient's mobile telephone number if it was sent to China, the file name, the page count, the price, the tracking number and, where we have recorded it, the date on which Australia Post's tracking records show the Letter as delivered, held for collection or not delivered, for receipts, support and billing dispute resolution. We delete the recipient's name, street address and any telephone number, and your return address and telephone number, 60 days after Australia Post's tracking records show the Letter as delivered or, if we have not recorded its delivery within 90 days after the Letter is Despatched, 90 days after it is Despatched. If those records show the Letter as held for collection or not delivered, and not later as delivered, we instead keep them until 60 days after we record that, if that is later, so that you can show where the Letter was sent if there is a dispute about it. For a Letter that is not Despatched, we delete them 30 days after you pay for it. After that we keep only the recipient's suburb, state, postcode and country. We delete those, the file name and the tracking number 18 months after you pay for the Letter. We keep the rest of the record, which shows the transaction, for as long as Australian tax and record-keeping law requires (generally seven years from the date of the transaction), after which it is deleted or de-identified, except as our Business Agreement provides for a Business Account

Letters are physical items once printed. We are not responsible for who opens or reads a Letter after it has been Despatched. For full details on how we handle personal information, please refer to our Privacy Policy (https://unopost.com.au/privacy).

14. Disclaimer of warranties

We provide the Service with due care and skill, but we cannot promise that it will always be available or error-free. Nothing in these Terms excludes, restricts or modifies the consumer guarantees under the Australian Consumer Law, which apply to our Service and cannot be excluded. Everything in this Section applies subject to those guarantees.

Without limiting the foregoing, we do not warrant that: (a) the Service will be uninterrupted, timely, secure or error-free; (b) any Letter will be delivered by a particular date or time, in good condition, to the intended recipient, or at all; (c) any Letter will achieve a particular legal or practical outcome; or (d) any defects in the Service will be corrected.

We are not responsible for the performance, reliability or availability of Australia Post, internet service providers, or any other third-party network or service.

15. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL UNOPOST, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, MISSED DEADLINES, LOST LEGAL RIGHTS OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE SERVICE, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, STRICT LIABILITY OR OTHERWISE) AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Our total aggregate liability to you for all claims arising out of or relating to these Terms or the Service shall not exceed the greater of: (a) the total amount paid by you to Unopost in the twelve (12) months preceding the event giving rise to the claim; or (b) one hundred Australian Dollars (AUD $100).

Where the Australian Consumer Law applies and section 64A of the Australian Consumer Law permits our liability for failing to comply with a consumer guarantee to be limited, our liability is limited, at our option, to supplying the Service again or paying the cost of having the Service supplied again. Because we delete your document once your Letter is Despatched, we can supply the Service again only if you give us the document again; if you do not, we pay the cost of having the Service supplied again. Where section 64A does not permit that limitation, including for services of a kind ordinarily acquired for personal, domestic or household use or consumption, this paragraph does not apply to you.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud, gross negligence, death, or personal injury caused by negligence, or any liability under the Australian Consumer Law that cannot be excluded.

16. Indemnification

You agree to indemnify, defend and hold harmless Unopost and its officers, directors, employees, agents and affiliates from and against any third-party claims, demands, losses, damages, liabilities, costs and expenses (including reasonable legal fees) arising out of or in connection with:

  • The Content you send through the Service, including any claims of defamation, harassment, intellectual property infringement or illegality
  • Your use of the Service to misrepresent your identity or the identity of any person or entity
  • Your breach of these Terms or of any applicable law in connection with your use of the Service

17. Force majeure

We shall not be liable for any failure or delay in performing our obligations under these Terms where such failure or delay results from a Force Majeure event. In such circumstances, our obligations shall be suspended for the duration of the Force Majeure event. We will use reasonable endeavours to mitigate the effects of any Force Majeure event and to resume performance as soon as practicable.

18. Modifications to terms

We may modify, amend or replace these Terms from time to time. When we do, we will post the revised Terms on this page and update the "Last updated" date at the top of it. For material changes, we will also post a summary of the changes on our website at least 14 days before they take effect.

Your continued use of the Service following the posting of any changes constitutes your acceptance of those changes. The Terms in effect when you pay for a Letter apply to that Letter. If you do not agree to the revised Terms, you must discontinue your use of the Service.

19. Severability and waiver

If any provision of these Terms is found to be invalid, illegal or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it valid and enforceable, or if modification is not possible, shall be severed from these Terms. The remaining provisions shall continue in full force and effect.

The failure of Unopost to exercise or enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by an authorised representative of unopost.

Survival: The following sections shall survive the termination or expiration of these Terms: Intellectual Property, Disclaimer of Warranties, Limitation of Liability, Indemnification, Entire Agreement, Governing Law and Jurisdiction. The provisions of the Business Agreement that it says survive its termination also survive.

20. Assignment

We may assign or transfer our rights and obligations under these Terms to any successor entity, affiliate, or purchaser of all or substantially all of our assets, without your prior consent. In the event of such assignment, we will notify you by updating these Terms or by posting a notice on our website. You may not assign or transfer your rights or obligations under these Terms without our prior written consent.

21. Entire agreement

These Terms constitute the entire agreement between you and Unopost with respect to your use of the Service. They supersede all prior or contemporaneous communications, proposals, representations, understandings and agreements, whether oral or written, between you and Unopost relating to the subject matter hereof.

No statement, representation, warranty or undertaking made by Unopost in any marketing material, support correspondence, automated support chat or other communication shall form part of these Terms unless expressly incorporated herein or displayed on the website at the point of payment. Nothing in this Section excludes, restricts or modifies any liability we have for misleading or deceptive conduct, or any right or remedy you have under the Australian Consumer Law.

These Terms are drafted in English. In the event of any conflict between a translated version of these Terms and the English version, the English version shall prevail. The Website and the Privacy Policy are also made available in languages other than English for your convenience only, and where a translation differs from the English version, the English version prevails. The business portal and the Business Agreement are provided in English only.

22. Dispute resolution

If a dispute arises out of or in connection with these Terms or the Service, the parties agree to follow this stepped process before commencing court proceedings:

Step 1: Informal resolution. You must first contact us at support@unopost.com.au with a written description of your complaint. We will endeavour to resolve the matter within 10 Business Days of receipt.

Step 2: Mediation. If the dispute is not resolved informally within 20 Business Days of the date Unopost receives your written complaint, either party may refer the dispute to mediation administered by the Resolution Institute (https://resolution.institute) (or its successor body) in accordance with its mediation rules then in effect. The mediation will take place in Melbourne, Victoria, unless the parties agree otherwise. For claims where the amount in dispute is less than AUD $500, Unopost will bear the costs of mediation. For all other claims, the costs of mediation will be shared equally between the parties. In all cases, each party will bear its own legal costs.

Step 3: Court proceedings. If the dispute is not resolved within 30 Business Days of the mediation commencing (or if mediation is declined by either party), either party may commence court proceedings in accordance with Section 23.

Nothing in this clause prevents either party from seeking urgent interlocutory or injunctive relief from a court of competent jurisdiction at any time. Nothing in this clause prevents you from lodging a claim with the Victorian Civil and Administrative Tribunal (VCAT) (https://www.vcat.vic.gov.au) or any equivalent tribunal in your jurisdiction. This dispute resolution process does not limit any rights you may have under the Australian Consumer Law or equivalent consumer protection legislation to lodge a complaint with a relevant regulatory body, including the Australian Competition and Consumer Commission (ACCC) or a state or territory consumer affairs agency.

23. Governing law and jurisdiction

These Terms are governed by and construed in accordance with the laws of the State of Victoria, Australia. You irrevocably submit to the non-exclusive jurisdiction of the courts of the State of Victoria and the Federal Court of Australia sitting in Victoria for the resolution of any disputes arising out of or in connection with these Terms or the Service.

Nothing in these Terms limits any rights you may have under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010 (Cth), https://www.legislation.gov.au/C2004A00109/latest) or any other applicable consumer protection legislation that cannot be excluded by agreement.
