The old way
Certified Mail, at the counter
- Write the letter, print it, and find an envelope that fits it.
- Address it by hand — including a return address, which USPS requires on every certified piece.
- Drive to the post office during opening hours and join the line.
- Fill in PS Form 3800 at the counter, peel it, and stick it on the envelope yourself.
- Decide at the window: the paper green card (PS Form 3811) or the electronic Return Receipt.
- Pay at the window, in cash or card, plus your own printing and envelope.
- Keep the stamped Form 3800 somewhere you will still have it in a year. It is your only proof of mailing.
Ten minutes at the counter with no line. Then do it again for the next recipient.
This way
Certified Mail, from where you are
- Paste the letter, or upload the PDF.The composer renders the exact pages that will print — fonts, pagination, everything.
- Type the two addresses.Both are checked against USPS data before you are asked to pay.
- Pay $12.99, or $14.99 with the electronic Return Receipt.We print it, seal it, and hand it to USPS the next business day. Tracking number by email.
About two minutes. No form, no line, nothing to lose.
Or hand it to an assistant: the same send runs over MCP, the API, or the CLI.

People who need it to hold up
The letter is the evidence: Certified Mail, a checked address, and a tracking page you can hand to a lawyer.

What a send actually looks like
We haven't launched, so there is no one to quote yet. These are written examples of jobs the product does today: the people are made up, the capabilities are not.
A solo founder sending a contract notice
The agreement says notice by certified mail, return receipt requested — so that is exactly what gets picked, and the receipt records both the mailing and who signed for it. Certified envelopes never carry our mark, so the letter arrives looking like it came from the company that sent it.
A property manager mailing 40 tenants the same notice
A CSV export becomes 40 individually addressed First-Class letters in one pass — no mail-merge document, no campaign platform. Rows with a repaired ZIP or a missing city are flagged before anything prints, and each letter is tracked on its own afterwards.
A tenant chasing a security deposit
The demand goes Certified with an electronic Return Receipt, which is what makes the statutory clock provable rather than merely started. That receipt records who signed for it and when — the exact record a security-deposit dispute turns on.
An engineer wiring mail into an agent
The agent quotes the letter for free, then calls send and gets back a payment link for a human to approve — it cannot spend on its own. The same path runs end to end in the sandbox, free, with nothing printed.
One price. Postage included.
Printing, the envelope and USPS postage are in the number, no matter which surface you send from.

Send a letterCommon questions
Do I need an account?
No. Pay per letter with a card or Apple Pay. Your email gets a receipt and a private tracking link, and that is the entire relationship.
Can I see the letter before I pay?
Yes. The composer renders the exact PDF, fonts and pagination included, for free. You pay once you are ready to send.
What file types can I upload?
A ready-made PDF, or paste plain text and let the composer typeset it.
How fast does it mail?
Usually the next business day — printed, sealed in a windowed envelope, and handed to USPS.
What does it cost?
One all-in price: $1.99 First-Class (extra pages $0.25, color $0.50/page, tracking $0.99), $12.99 Certified, $14.99 Certified with the electronic Return Receipt, $24.99 Priority.
Other ways to send
We support your method too — web, email, text or the CLI, one all-in price either way.
