Print envelopes
from your iPhone.
Paste an address. Pick your envelope. Tap Print.
$1.99 one-time. No subscription. No account.
Paste an address. Pick your envelope. Tap Print.
Name, street, apartment, city, state, ZIP — recognised from anything you paste. Spelt-out states become USPS codes. "Avenue" becomes "Ave". Missing ZIPs get flagged before you waste a stamp.
The whole envelope morphs proportions when you switch sizes. Drag it left or right and it rotates so you can see the front, the flap, and the wax seal — exactly the envelope you'll be holding when it's printed.
11 envelope sizes, from #6¾ to 9×12. And custom for anything weird.
5160, 5161, 5162, 5163, 5164, 8163, 8164. Tap exactly the cells you want — print 6 stickers without wasting the rest of the sheet, or hit "fill all" when you need every cell.
Stick-on labels too. Dymo, Brother, thermal — ¾×2½ up to 4×8.
Take a screenshot of a TCGplayer, eBay, or Etsy order page. Drag it into the Bulk tab. Posthaste reads every recipient address on-device with Apple's Vision framework — no servers, no uploads.
Edit any address, deselect any rows, then print the whole batch to envelopes, single labels, or a sheet of Avery stickers.
Drag the address block anywhere on the envelope. Smart guides snap you to dead centre, every corner, and the centre axes. Live margin readouts show how much room you have on each side.
Add your own logo above the return address — auto-sized for uniform output across every envelope you print.
If you ship Pokémon, MTG, or sports cards in plain white envelopes, Posthaste is the PWE printer you've been waiting for. Drop a TCGplayer or eBay order screenshot into the Bulk tab and print every envelope in a single batch.
No servers. No analytics SDK. No third-party trackers. The OCR runs locally with Apple's Vision framework — your screenshots are read on-device and never uploaded.
