Gmail API vs Agentic Email: What Should AI Agents Use?
https://robotomail.com
Does your AI agent need access to someone's Gmail — or its own email identity? These are two different jobs, and picking the wrong one makes the whole build harder.
This video walks both rails fairly, straight from the source:
• The Gmail API rail — OAuth consent, scopes (gmail.readonly, gmail.send), and users.messages.send. Google's own docs call it "the best choice for authorized access to a user's Gmail data." That's exactly what it's for: an app acting as a guest in a mailbox a human already owns.
• The Robotomail rail — the agent's own identity. One POST to /v1/mailboxes creates a real address ([email protected]). You authenticate with an API key (no browser, no consent screen). A signed webhook fires message.received with the sender, subject, and parsed body, and the agent replies in-thread with inReplyTo. Receive → event → reason → reply, fully autonomous.
The verdict: choose the Gmail API for an authorized Google mailbox integration; choose Robotomail when the agent itself needs to be the email identity.
