Gmail for AI Agent

Gmail can work for an AI agent that needs existing conversations or must send from a Gmail address. The setup needs appropriate OAuth permissions, quota handling and a clear boundary around the messages the agent may access. Google documents both the Gmail API and a Gmail MCP Developer Preview.

Give each AI task its own receiving address with Revdoku. Give each agent access to the mailbox it needs and receive messages and attachments there. See email capabilities.

What the Reddit suspension story tells you

In a Reddit report about an agent’s Gmail account, the author reports that a new account was disabled on day three despite sending below the headline limits; the title says 48 hours. We cannot independently verify either.

This anecdote does not establish Google’s enforcement policy. It establishes neither that Gmail prohibits agents nor that sending below limits guarantees continued account access.

For AI integrations, Google documents a Gmail MCP server in Developer Preview. Distinguish connecting an existing Google identity from provisioning separate inboxes for agents and applications.

Separate Gmail sending limits from Gmail API quotas

Google says personal Gmail may show sending-limit errors above 500 emails daily or 500 recipients per message. Sending may resume within 1–24 hours. This is a sending restriction, not an account-ban threshold. Personal Gmail limits.

Paid Google Workspace allows up to 2,000 daily messages per user; trial accounts allow 500. Recipient limits and account context matter. Workspace sending limits.

The Gmail API separately applies method-weighted project and user quotas. These changed in May 2026; qualifying older projects retain previous quotas. Check your project’s allocation. Handle quota errors with bounded exponential backoff and jitter. Jitter staggers retries to avoid synchronized load. Gmail API quotas.

Reduce backend polling with Gmail’s watch notifications through Cloud Pub/Sub. Renew watches before expiration and maintain synchronization, recovering from missed notifications. Gmail push notifications.

Choose Gmail OAuth scopes for the task

Google documents these scopes (names shortened):

Your app’s label or search filters do not narrow token permissions. Request the broad mail.google.com scope only as needed. Gmail add-ons offer current-message scopes for distinct interactive use. Gmail scope reference.

Scopes can change after app creation. Google supports incremental authorization: add access as needed, with appropriate user consent and applicable verification. Google OAuth best practices.

An agent sending only approved notifications can request gmail.send. Reading a user’s inbox requires an appropriate reading scope, even when code selects only invoice messages.

Extra addresses are not separate agent inboxes

Gmail plus addressing sends address+tag mail to the same inbox. It organizes arrivals without creating an independent account or agent permission boundary. Gmail address variations.

Workspace administrators can add up to 30 free aliases per user. These route to that user’s mailbox. Workspace aliases.

Google’s separate 12-month rule covers creating primary @gmail.com addresses on eligible existing accounts, at most three times total. The old address remains an alternate; both share an inbox. It is not a blanket alias limit. Google Account address changes.

Revdoku aliases likewise share mailbox history, quotas and permissions without changing the primary address. They require administrator permission and available alias allowance. See mailbox aliases and account limits.

For different agent access, use separate mailboxes.

A three-inbox Revdoku agent architecture

For example, create three Revdoku mailboxes with separate receiving addresses, and three separate agent connections:

Use the email addresses returned when you create the mailboxes.

Authorize each Revdoku agent connection separately

Use the Revdoku skill, CLI, MCP or API and follow its authorization flow. Select only the required mailbox and permissions; grant write access to save output. Revdoku permissions cover accounts or selected mailboxes, not arbitrary folders. See connection setup and the API guide.

Keep the original message available

Keep the original email and attachment alongside the agent’s result so a person can check its interpretation. Revdoku stores decoded messages and files; your agent or application performs document extraction. Link the result to its source message and attachment. Email and file API.

Choose an AI agent email inbox for the job

Keep Gmail for existing conversations or a Gmail sending identity; choose Revdoku for separate intake workspaces. Combine them: review a proposed reply in Revdoku, then send through a separately authorized Gmail integration or outbound provider.

For selected messages already arriving in Gmail, follow the Gmail forwarding guide.

See Gmail vs Revdoku. For a separate receiving workspace, create a free inbox.

Look at inbox workflows for Meta Muse, Instinct, and ChatGPT dots.
