Can I send one-off postcards where every piece is different?
Yes, and it is a supported pattern rather than an edge case — several customers run exactly this in production. There is no minimum order and no volume commitment, so a single postcard is a valid send. Each piece can carry completely unique front and back artwork: create a template from your own print-ready PDFs with POST /v1/templates/create (pass published: true to create and publish in one call), then reference that template_id on the send. To mail many unique pieces at once, POST /v1/postcards/batch accepts up to 500 items and each item carries its own template_id, so 500 completely different postcards go out in a single request.
Can I supply my own print-ready PDFs instead of using your designer?
Yes. Supply a front and a back PDF by URL when you create a template and we print your artwork as-is, adding only the postal elements. For 4x6 the file should be 6.25 x 4.25 inches (450 x 306 pt, trim plus 0.125" bleed per side), one page per file. We compose the recipient address, return address and postage indicia onto the front, so leave that area clear — GET /v1/specs returns the exact geometry for every size and both address layouts. There is no way to attach a PDF directly to a send: artwork always goes through a template first.
Can I see what a postcard will look like before I pay for it?
Yes, and it costs nothing. Send with test mode on: the piece is composed and rendered exactly as it would print — your artwork with the address block, return address and postage indicia applied — but nothing is charged and nothing is mailed. Fetch the result and open the PDF. Poll for the PDF rather than for a status change: a test piece deliberately stays at status "created" because it never enters the print queue.
When does a postcard actually get mailed?
Pieces submitted during the day are batched and sent to our print partner at 2am Vancouver time. You can cancel a piece up until 23:59:59 Vancouver time on the day you submitted it; after the batch runs it is committed to production.
How long until my postcard is printed and mailed?
Pieces approved during the day go to our print partner in the nightly batch at 2am Pacific. Their production turnaround is currently 1–3 business days from that handoff, after which the pieces enter the mailstream. Canada Post delivery time is on top of that and varies by destination and mail class. We do not quote a delivery date: Lettermail carries no per-piece tracking and no delivery guarantee, so any number we gave you would be an estimate we could not stand behind. If you want a read on when a piece landed, the QR code add-on gives you a real scan signal.
What paper stock and finish do you print on?
Postcards print on 100lb stock, digitally, with a choice of glossy or matte finish. There is no UV coating. You choose the finish per piece and postcards default to glossy. If your product depends on a UV-coated or specialty stock, we are not currently a fit — we would rather tell you that before you integrate than after.
Do you send physical samples?
No — we do not send sample packs. The way to judge our print quality is to place a small real order and receive it yourself, which costs no more than any other send because there is no minimum. Address a few postcards to your own address through the dashboard campaign manager or the API and you will get exactly what your customers would get: same stock, same press, same mail path. That is a better test than a sample pack anyway, because it exercises your artwork rather than ours.
Can I pay for rush or priority production?
Not currently. Every piece follows the same schedule: the nightly 2am Pacific batch, then 1–3 business days of production, then Canada Post. There is no premium tier that shortens it today. If that changes we will say so.
Do you publish a template showing the safe and restricted areas?
Yes. There is a two-page design guide PDF for every size — 4x6, 5x7, 6x9 and 6x11 — in both address layouts, showing trim, bleed, the safe zone, the address box, the 22x40mm postage indicia clear zone and the 20x10mm return address zone. Download them from the help page in your dashboard, or directly at https://api.postally.ca/v1/docs/download/postcard-design-guide-4x6 (swap the size for other formats, and add -classic for the divided-back layout). GET /v1/specs returns the same geometry as numbers if you would rather drive your renderer from data.
