- “Find the lease agreement PDF someone sent me in September and tell me the notice period.”
- “List every message from my accountant this quarter across all accounts.”
Good to know

- ChatGPT may ask you to confirm each tool call; all calls are read-only and appear in your Emailgents Activity page.
ChatGPT questions
Why not just use ChatGPT's Gmail app?
Use it if one Gmail account is all you need. Emailgents is for everything else: more than one account, Outlook and Gmail together, iCloud, Yahoo, Fastmail, AOL, Zoho, GMX and any IMAP server, with a read-only guarantee and an access log.
Which inboxes will it see?
Every mailbox you have connected in Emailgents: Gmail and Google Workspace, Outlook and Microsoft 365, iCloud, Yahoo, Fastmail, AOL, Zoho, GMX, WEB.DE and any IMAP server. Add or remove mailboxes in Emailgents and the agent sees the change on its next call.
Can it read several accounts at once?
Yes. search_messages and inbox_overview cover every connected mailbox by default. Pass account_ids to narrow to one; each result carries its account so the agent can tell them apart.
Can it send, delete or move my mail?
No. The tool set is read-only apart from set_flags, which toggles read and starred. An instruction hidden inside an email cannot make the agent send anything on your behalf, and every call is listed on your Activity page.
