Certified Mail from your AI

Your AI writes the letter. Piloxa mails it — and keeps the proof.

Paste your letter or hand it over from ChatGPT, Claude, Gemini or Grok. We print it, send it by USPS Certified Mail, track it, and keep the mailing record together with the exact document.

From $13.18 · $16.17 with Electronic Return Receipt

One letter. One payment. No subscription, no membership, no minimum, no trip to the Post Office.

Three steps

1. Write

   Draft anywhere — ChatGPT, Claude, Gemini, Grok, or your own document. Paste the text, attach a finished PDF, or let a connected assistant hand it over.

2. Review

   See the exact pages, the recipient address after USPS checking, the mailing service and one total. Edit it if you like, then authorize with your card.

3. Mail and prove

   Piloxa prints and mails it USPS Certified. The exact document, its fingerprint, your authorization and whatever the printing partner reports back stay together as one record.

What you hold afterwards

Four things, kept together and downloadable as one file. This is the chain the sample record shows, stage by stage.

1. The documentThe exact file you approved, byte for byte, with its SHA-256 fingerprint.
2. Certified envelopePrinted, enveloped and handed to USPS as Certified Mail, with the printing partner’s own acceptance kept verbatim.
3. The authorizationWhat you approved, what you were charged and the moment you agreed to it, in your own words.
4. Tracking, as it is reportedEvery scan and signature the printing partner passes back, each with its source — and a plain “no record yet” where none has been reported.

The first three exist the moment the letter is accepted. The fourth depends on what the printing partner reports back, and Piloxa never fills a gap by assuming the next step happened. See a sample mailing record — including what can be missing and why.

No team to name, no plan to choose, no case to open. One letter is the whole job, and pasting works with no connector — connecting an assistant only skips the copy-and-paste.

What you are paying for

USPS Certified Mail with electronic return receipt costs $9.28 in postage and fees at the counter, and that assumes you print the letter, drive there and stand in the line. Count the drive at the IRS mileage rate and an eight-mile round trip is $5.80 more, so the trip is about $15.08 before a single minute of your time is valued — the arithmetic is on the pricing page. Today a one-page letter sent Certified Mail is $13.18 all in — printing, the envelope, postage and the certified fee, with USPS tracking. Adding the electronic return receipt, which is the record of who signed for it, makes it $16.17 all in. Longer letters cost a little more. The exact total is on the review page before you pay, and there is no second charge afterwards. The receipt, tracking history and signed return receipt are stored with the letter, so nothing has to be saved by hand. See the price for every length of letter.

Three rules Piloxa never breaks

No accidental mailing. An assistant can prepare, explain and route. A person approves the exact, locked document before payment and before anything is printed.

No duplicate mailing. Every action carries a stable identity; an uncertain outcome is queried, never blindly retried.

Exact-document preservation. Every mailing references one locked version of the file, with its SHA-256 fingerprint and page count. What was mailed is never a matter of memory.

Common questions

Does the AI send the letter by itself?

No. The assistant prepares it and gives you a review link. Nothing is printed, mailed or charged until you open that link, read the pages and authorize the payment yourself.

Do I have to connect my assistant?

No. Copy the letter out of the chat, sign in to Piloxa with your email, press Paste the letter text, and fill in who it is from and to. Piloxa lays it out as a PDF you can still edit before you pay. Connecting an assistant only saves the copy-and-paste. Piloxa cannot read your chats — what you paste or hand over is all it ever sees.

Which assistants work with Piloxa?

Any assistant that lets you add a remote custom connector: Claude on Free, Pro, Max, Team and Enterprise plans (Free allows one custom connector); ChatGPT on Business, Enterprise and Education workspaces on the web; and Gemini custom apps inside Gemini Spark for eligible Google AI Pro or Ultra personal accounts. Piloxa has tested Claude, ChatGPT and Grok end to end. Availability changes, so check the linked official requirements on the send-a-letter page.

What proof do I get?

Always: the exact document that was printed, with its SHA-256 fingerprint, the addresses, the service you bought, what you authorized and paid, and the printing partner’s own acceptance of the job, kept word for word. Then, as they are reported back: the USPS tracking events and, if you chose that service, the electronic return receipt with the signature. Piloxa records those the moment they arrive and says “no record yet” until they do, rather than assuming. The sample record shows every state, including the incomplete ones.

Is this legal advice?

No. Piloxa executes and documents the mailing. What the letter says is yours, or your lawyer's. When a deadline or a lawsuit is involved, have a lawyer read it first.
