What it does
The specific capability behind this listing, and where to get it.
Connect the mailbox you already own, on Microsoft 365, Gmail or any IMAP host, and your AI can genuinely use it: read, search, draft, reply in thread, forward with everything the original carried, and file mail away. **It behaves like a mail client, not an API wrapper.** Replies carry In-Reply-To and References, so they nest inside the conversation in the recipient's client. Reading a message does not mark it read. Exactly one copy is filed in Sent. Moves use IMAP MOVE, so read state, flags and original dates all survive. Deletes go to Trash. **Batches are the economics.** Up to 500 messages moved, filed or flagged in one call, and 501 is refused rather than silently truncated. A call is the metered unit, so triage does not burn your quota a message at a time. **Attachments never pass through the model.** A file already in the mailbox, one at a web address, or one uploaded from your own computer is streamed at send time, so a 6 MB PDF costs the same as a sentence. **Nothing of your
