Mailbag
Terms of Use
Published by Benjamin Jacobs (SwellStack Co). Effective 2026-11-15.
The license
Mailbag is licensed to you under Apple's Licensed Application End User License Agreement (the standard EULA) at apple.com/legal/internet-services/itunes/dev/stdeula. That agreement governs your use of the app. The terms below add the details of the purchase and what the app can and can't do. Where they differ, Apple's EULA wins.
What is free
Mailbag is a free download. Picking people, choosing a sheet, seeing the sheet and printing test pages and practice pages are always free. Your first sheet of labels (or your first 3 envelopes) prints or shares in full, with no watermark. It counts once the print or share finishes. The count is kept on your device and carries over if you delete and reinstall the app.
Mailbag Unlimited
After the free sheet, printing and sharing need Mailbag Unlimited, a single in-app purchase paid once. It is not a subscription and nothing renews. It unlocks every sheet and envelope in the app. Family Sharing is on. The app shows the price in your local currency before you buy.
Refunds
Apple handles all payments, so refund requests go to Apple at reportaproblem.apple.com. We can't issue refunds ourselves.
Restoring a purchase
On a new device, or after you reinstall, open Mailbag's Settings and tap Restore purchase while signed in with the Apple Account you paid with. Restore is also on the purchase screen.
What the app can't do
Mailbag draws each page at true size, but your printer decides where the ink lands. Printers feed paper at slightly different positions and some stretch the page. The free test page and the per-printer fix are there to find and correct that. Mailbag makes no promise that a label sheet or envelope will line up on any particular printer, and you are responsible for checking a test page before you print on label stock.
Mailbag prints on US Letter label sheets and on #10 and A7 envelopes. It does not print shipping labels or postage.
Trademarks
Avery is a trademark of Avery Products Corporation. Product numbers are used only to help you find the matching sheet. Mailbag is not made or endorsed by Avery.
Changes
If these terms change, the new version will be posted on this page with a new effective date.
