Start with a finished PDF

Use an unencrypted PDF, at most 10 MiB, with portrait US Letter pages measuring 8.5 × 11 inches. Save your final wording into the file before requesting a quote. Postedly prints the file you approve.

  • A separate address page is added to letters and certified mail. Review its placement in the final proof.
  • The upload system accepts PDFs with 1–50 pages, but this is not a mailing allowance. The current letter service permits at most six physical sheets including its address sheet; the selected mailing and printing options can have lower page limits.
  • A document that uploads successfully can still fail the service-specific quote checks. Follow the returned page or size correction before trying again.

Supported addresses

Letters, certified mail, and postcards currently require complete sender and recipient addresses in the 50 United States or Washington, DC. Include the name, street address, apartment or suite when needed, city, two-letter state, and ZIP code. International addresses and US territories are not supported by the current mail address validation.

  • A connected assistant can reuse your verified sender email for order updates. A new website session asks you to verify it securely.
  • Check the address in the final proof, including any postal correction returned during quoting.

A quote for your document

The current letter service has a fixed price within its eligible document and printing limits, before applicable tax. The quote checks your actual document, including the added address page. The selected mail product determines color, sidedness, and mailing class; custom options are not automatically available.

Review the exact order before payment

Review the final proof, recipient, sender, service, estimated timing, and total. Your connected account reuses its verified email; a new website session may require verification. Confirm the sending details and terms before continuing to payment. The normal website and assistant review flow uses hosted Stripe Checkout.

A draft, upload, connection, or quote does not pay or send. If the document, address, options, or price changes, request a new quote and review it again. An expired quote also needs to be replaced.

Timing and what the status means

Printing and postal transit take several business days. Use the estimate shown in your quote; it is not a guaranteed arrival date.

Order updates can show preparation, printing, and postal progress. A sent update or estimated arrival does not necessarily confirm that the recipient received the item. Read the sending record for the evidence actually available.
