AgentMail

Email inboxes via API for AI agents

What it is

AgentMail is an email provider for AI agents where you create inboxes through an API, as many as you need. Agents use them to send and receive mail, threads and attachments included, and webhooks or WebSockets notify them about new messages straight away. Custom domains with DKIM, SPF and DMARC are supported, and besides SDKs for Python and TypeScript there is a CLI and an MCP server.

Install
npm install agentmail dotenv
Why it made the cut
