client = AgentMail()

inbox = client.inboxes.create(
    username="hello",

)

[ FAQ ]

Frequently asked
questions.

AgentMail is an API-first email platform designed specifically for building AI agents that can communicate over email. While traditional email APIs are built for sending one-way notifications, AgentMail is built for two-way conversations, making it easy to create agents that can read, understand, and reply to emails in a thread, just like a human would.
