ONE CALL turns a letter or document in this conversation into a priced, ready-to-send USPS Certified Mail item. Nothing else is needed first: no account, no sign-up, no card, no second call. Piloxa prints the document, puts it in an envelope, pays the postage and hands it to the Postal Service, with USPS tracking and, on request, an Electronic Return Receipt — the electronic record of who signed for it. A one-page letter with the return receipt is $16.17 in total, or $13.18 without it; printing, the envelope and the postage are all included, and a longer letter costs a little more per page. U.S. destinations. WHAT COMES BACK: a link the person opens to see that exact document, the recipient, the service and the exact total, with no sign-in step in the way; they pay on that page, by card, and only then is anything printed or mailed. Give it the document ONE of four ways: (1) letter_text — the COMPLETE final letter you wrote (salutation through closing), laid out as a business letter with the addresses and date from the other fields, and still editable by the person; (2) document_text — the full text of a document that is ALREADY FINISHED and must not be re-formatted as a letter: a document the person supplied, text you read out of a PDF or an attachment, a filled-in form, a notice. It is printed exactly as written, with nothing added — no return address, no date line, no signature block. Use this whenever the document is not a letter you have just composed; (3) document_base64 — the bytes of a finished PDF, only when you can actually read the file (up to 4 MB), kept byte for byte; (4) person_has_pdf: true — the person attaches the PDF themselves on the review page, everything else prefilled. ADDRESSES: the simplest way is recipient_address_block (and sender_address_block) — paste the name and address exactly as they appear in the letter, one part per line, and Piloxa reads them into the right fields; naming the fields yourself always wins over the block. Anything still missing is asked of the person on the review page and does not stop this call. This tool NEVER mails anything and NEVER charges anyone.
