AgentMail is an email service API built for AI agents that gives each agent its own real inbox that it can create, use and keep over time. Instead of plugging an agent into your personal Gmail account, you set up a fresh inbox with a single API call, and the agent can then send messages, receive replies, handle attachments and keep conversations threaded, with webhooks alerting it the moment new mail arrives. The platform offers a generous free plan with 3 inboxes and 3,000 emails per month – paid tiers and enterprise options are available for larger teams.
