LetterAgent
Mail physical letters by just asking your AI assistant.
Home > Guides > Who can read your letter
When you use an online mailing service, the service's own staff and systems see your letter during printing and handling, but the postal workers and machines that carry it see only the envelope. LetterAgent keeps this circle small: your letter is printed exactly as quoted, handled only for printing and mailing, and your data is not used for anything else.
| Who | What they can see |
|---|---|
| The mailing service's production staff | Your letter's content while printing, folding, and inserting |
| The service's computer systems | Your file while it is being processed |
| Postal workers and sorting machines | Only the envelope: addresses and postage |
| The recipient | Everything, once it is delivered |
Someone has to print it. The service's production staff and its automated systems handle your file to print it, fold it, and get it into the envelope. Your document also passes through the service's servers on the way there. This is true of any online mailing service, and it is the main privacy difference between mailing a letter yourself and mailing one through a service. When you mail it yourself, nobody sees the contents between you and the mailbox. When a service mails it, the service is part of the chain.
What varies is how seriously the service treats that position. A good one limits access to the people and systems that do the actual printing, keeps documents only as long as the job needs, and does not mine your letters for data. A bad one might keep copies indefinitely or share data with third parties. This is worth checking in any service's privacy policy before you send anything sensitive.
Only the envelope. Postal workers and sorting machines read the addresses and the postage, never the contents. In the US, sealed first-class letters are protected from inspection: postal inspectors need a warrant to open one, which is a stronger protection than most people realize. In Canada, mail is similarly protected while it is in the post. Once your letter is sealed in the envelope and in the mailstream, it travels like any other letter. The postal service does photograph envelopes for its sorting and tracking systems, but those images show the outside, not the pages inside.
LetterAgent runs on a minimal-data principle: your letter is printed exactly as quoted and handled only for printing and mailing. There is no account holding your documents, no subscription profile building up a history of what you send, and no use of your data beyond completing the job itself. You describe the letter to your AI assistant, approve the exact quoted price, pay once, and it is printed and mailed. The status box at the top of this page notes the service is in private testing; the same careful handling applies now.
First, use the envelope properly. LetterAgent's standard double-window envelope shows only the addresses through the windows, so nothing about the contents is visible from outside. Second, consider the registered option: US Certified Mail or Canada Registered Mail adds tracking and proof of delivery, so you know exactly where the letter went and who signed for it. Third, keep your own copy of exactly what you sent. And be honest with yourself about the limit: if a letter is too sensitive for any third party to see at all, the right move is to print and mail it yourself.
