Mail physical letters by just asking your AI assistant.
Every LetterAgent letter is a real, physical letter printed and mailed through our print partner. Here is exactly what shows up in the recipient's mailbox:
| Detail | What it is |
|---|---|
| Paper | 8.5″ × 11″ (US Letter), for both US and Canadian letters |
| Printing | Single-sided; black-and-white or colour, exactly as quoted |
| Addresses | The recipient's address and the sender's address are printed at the top of the first page |
| Envelope | Standard double-window business envelope. The recipient's address shows through one window; the sender's address shows through the other and acts as the return address — undeliverable mail comes back to it |
| Postage | First-class postage (or the fastest available non-express service for the destination) |
| Not included | No extra inserts, flyers, or return envelope — just your letter |
What about the preview? The preview your assistant shows you is the letter content. At print time, the address block is added in the top section of the first page (keep that area free of your own text), and the content is printed exactly as quoted — the page count the quote verified is the page count that gets printed.
Registered mail (US certified, Canada registered) uses the same physical letter and envelope; it adds tracking and proof of delivery.
Machine-readable version of these facts: llms.txt ("Physical format" section) and SKILL.md.
