AgentMail
Freemium · $20/moEmail inbox API that gives AI agents their own addresses
What is AgentMail?
AgentMail is email infrastructure built for AI agents rather than for people. One API call creates a dedicated inbox, and the agent can then send, receive and reply to messages in threads, handle attachments and react to incoming mail through events.
Typical uses include agents that hold two-way conversations with customers, process inbound email, coordinate schedules or sign up for services on their own. Replies stay grouped by thread, and an agent can hand a conversation to a human when needed.
SDKs cover Python and TypeScript, with a CLI, an MCP server and agent skills for wiring it into coding agents. Permissions control what each agent can read or send, pods keep each customer's inboxes and domains separate, and the service is SOC 2 Type II compliant.
