AgentMail
AgentMail is an API-first email platform that gives AI agents their own email inboxes to autonomously send, receive, reply to, and act on email. Unlike traditional transactional email APIs built for one-way notifications, AgentMail is designed for two-way threaded conversations: agents create inboxes on demand, read and semantically search messages, manage threads and drafts for human-in-the-loop review, apply labels and allow/block lists, and react to inbound mail in real time over webhooks or WebSockets. It ships a REST API (OpenAPI 3.1), an AsyncAPI 2.6 WebSocket surface, Python/Node/Go SDKs, a CLI, a hosted MCP server, and IMAP/SMTP bridges, with API-key permissions, idempotency, multi-tenant pods, custom domains, and SOC 2 Type I/II compliance.
AgentMail publishes 28 APIs on the APIs.io network, including agent API, api-keys API, auth API, and 25 more. Tagged areas include Company, Ai, Email, API, and AI Agents.
The AgentMail catalog on APIs.io includes 1 event-driven AsyncAPI specification.
AgentMail’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 27 more developer resources.
