LetterAgent
Mail physical letters by just asking your AI assistant.

LetterAgent prints letters only, so it can't send your original documents: a passport, birth certificate, or deed that exists on paper. Mail copies whenever you can. If you must send the original, use USPS Registered Mail or Canada Post Registered Mail, keep copies of everything, and never mail your only copy.
No. LetterAgent prints your letter text and mails the printout, which covers anything where a printed page is the document: a contract you drafted, a cover letter, a demand letter. It can't mail an original that already exists on paper: a passport, a birth certificate, a vehicle title, a naturalization certificate. Those need the physical item in an envelope, which means a trip to the post office or a courier counter.
One gray area: signed contracts. If both sides accept printed copies, a freshly printed contract works fine. If someone needs the page with the wet-ink signature, that page is an original and it has to travel physically.
| Document | Can you send a copy? | Safest way to mail it |
|---|---|---|
| Passport application supporting documents | Usually no: agencies want the originals | USPS Registered Mail in a rigid mailer |
| Court filings | Often: many courts accept certified copies | Check the court's rules first, then Registered Mail |
| Signed contracts | Often yes, if both sides agree | Regular or tracked mail is usually fine |
| Vital records you already hold | Send certified copies instead of the original | Order certified copies from the issuing office |
Ask the recipient before you risk the original. Many agencies accept certified copies: copies stamped or sealed by the issuing office, which carry more weight than a photocopy you made at home. Passport offices are the classic example. They ask for an original birth certificate, examine it, and mail it back to you, usually in a separate envelope that arrives days after your new passport. Knowing the original comes back on its own takes some of the fear out of sending it.
If you own a vital record outright, like your own birth certificate or marriage license, the safest move is to order two or three certified copies from the vital records office and mail those. They cost a small fee each, and if one goes missing you order another instead of replacing an irreplaceable document.
Before anything goes in the mail, scan or photocopy both sides. If the worst happens, a good copy turns a disaster into paperwork.
USPS Registered Mail is the gold standard. Every person who touches a registered item signs for it, creating a documented chain of custody from drop-off to delivery, and registered items travel separately from ordinary mail. Canada Post's Registered Mail works the same way. For documents, the custody chain matters more than speed: it makes loss close to impossible because the item is never anonymous in the system.
Packaging matters too. Use a rigid or padded mailer so sorting machines can't bend the document, and don't fold anything that shouldn't be folded. Write the address clearly or print it: a misread address is how originals end up in the wrong hands. Keep the mailing receipt and tracking number somewhere you can find them, and not inside the envelope.
With Registered Mail, true loss is rare precisely because of the custody chain: the tracking history shows the last person who signed for it, which gives the post office a place to start looking. For ordinary mail, file a missing mail search with USPS or a service ticket with Canada Post, and give them a precise description of the document. Then start the replacement process with the issuing agency right away instead of waiting. This is the whole point of the copies you made: with a certified copy or a good scan on hand, replacing the document is an errand, not an emergency.
