Why Unopost
Free tracking, every letter
Regular or Express Post, every letter gets an Australia Post tracking number at no charge. We email you when it's posted, and again when it's delivered in Australia. PostMyDoc charges $2 to track standard post.
Signed for, not left
Add signature on delivery to Express Post for $6, and it's handed over in person. PostMyDoc doesn't offer it on one-off letters.
Deleted the moment it's posted
Stored encrypted in Sydney, and gone once your letter is lodged. PostMyDoc keeps it up to 24 hours after posting. Names, street addresses and phone numbers, the recipient's and yours, are deleted 60 days after delivery. We keep only the suburb and your email for our records.
Colour at no extra cost
Colour or black and white, same price. 20 pages included, then $0.30 a page, up to 80.
Flat by Express Post
Express Post letters go flat in a B4 envelope, so certificates, photos and forms arrive uncreased.
Word and photos, not just PDF
Upload a PDF, Word document or phone photo and we lay it out on A4. PostMyDoc takes PDFs only.
