# Agent Mail

Agent Mail gives an AI agent a permanently reserved inbound email address through the mobilerun API. It is a first-party mailbox service, separate from controlling a user's Gmail account on a phone.

- Paid plans include mailboxes (Developer 10, Startup 25, Scaleup 100). Claim an included mailbox while capacity is available, or rent an extra one.
- Extra mailboxes are $2/month each and include 1,000 inbound messages per month.
- Choose a custom local part or let mobilerun create a random, non-guessable address.
- List messages with time, sender and OTP filters; retrieve sender, subject, text body and attachment metadata.
- Ask for the highest-confidence recent OTP, optionally filtered by sender, time and code length. Clients repeat the request from an SDK because the endpoint does not wait server-side.
- Archive or cancel without deleting the address or messages. Restart later with the same permanently reserved address.
- The documented Agent Mail API is inbound-only. Sending and replying belongs to Gmail app automation. SMS belongs to the eSIM messaging API: receiving on every plan, sending on Enterprise.
