Multiple Gmail accounts, one AI agent

How it works

1. Connect FGAC once ( three-step setup). Your own inbox works immediately, read-only by default.
2. Click + Add accounton your Accounts page and open the link it gives you signed in as the other Gmail account — your own second inbox, or a teammate's (send it to them). One click there delegates that inbox to you — no password sharing, no Google Workspace admin, no second FGAC account.
3. That's it — the delegated inbox attaches to your Default Profile automatically, read-only like your own. Your agent targets any inbox with the account parameter: “Check my work email”, “Summarize unread mail in the support inbox”.

Building a custom profile instead? Delegated inboxes stay opt-in there — pick the mailboxes when you create the profile. And when a delegation is revoked, the inbox disappears from every profile immediately.

Things people run across their inboxes

• Morning triage across work + personal email in one prompt
• An EA-style agent over a delegated executive inbox
• A support agent reading a shared team mailbox, send-restricted to your domain
• Sweeping receipts and travel confirmations from every account into one Google Sheet

Each inbox keeps independent guardrails: read rules that hide sensitive mail, send whitelists per profile, and one-click revocation of any delegation.
