How the list rate works
Estimated U.S. shipping time is 7–10 days.
Letters are priced by page 1 + extra pages. We count pages from your PDF (or the composed letter) on the client and again on the server. The first page is the class base; every page after that is $0.25, whether First-Class or Certified.
Postcards are a flat $1.99 per 5.5×4.25 piece. There is no extra-page line.
Optional full-color letter printing adds $0.49 per printed page per recipient. A one-page First-Class letter in color is $1.98. Select the upgrade in the First-Class box when preparing your mailing.
Electronic Return Receipt is an optional $2.40 add-on on Certified Mail only. It does not apply to First-Class or postcards.
Credits are 1:1 with USD cents. Optional coupon codes on the API and MCP change the charged or quoted cents. They do not change postage or delivery, and staging keys still never buy postage.
Which class to pick
First-Class
Everyday correspondence: invoices, thank-yous, notices that do not need proof of mailing. #10 envelope. Fastest path from PDF to USPS.
Certified Mail
When the piece should not vanish into ordinary First-Class — legal notices, demand letters, anything you may need to prove you mailed. Optional Electronic Return Receipt adds electronic delivery evidence.
Postcard
A 5.5×4.25 Express postcard with color included, with artwork on the front and the address on the reverse. Flat rate, no page overage. Use it for short notes, not multi-page documents.
How you pay
Credits
Top up in the workspace with a card on Square. Balance is 1:1 with USD cents.
Pay per send
Spend credits when you send, or pay for that piece by card. Stablecoin payments are available for developers.
People vs software
Same prices. Read the send guide or the hosted MCP docs.
Pricing questions
How are extra pages billed?
- Letters bill $1.49 (First-Class) or $12.99 (Certified) for the first page, then $0.25 for each additional page. Postcard is a flat $1.99 and has no page overage. Page count is taken from the PDF on the client and checked again on the server.
Is there a monthly subscription?
- No. You pay per piece. Credits are 1:1 with USD cents and never expire as a membership fee. Unused credits stay on the workspace.
When should I send Certified Mail?
- Use Certified when you need USPS proof of mailing — notices, legal correspondence, anything that should not disappear into ordinary First-Class. The $12.99 base includes the first page. Add Electronic Return Receipt ($2.40) when you want electronic delivery evidence.
How do I pay?
- Buy credits with a card on Square, then spend them on a send. Stablecoin payments for developers are documented on the x402 page. Optional coupon codes on API and MCP change the charged cents only — they do not change postage or delivery.
