What is Mails.ai?
Mails.ai gives an AI agent its own email address through one API call, so it can send, receive and reply. Replies, deliveries and bounces reach your code as signed webhooks or a live stream, and incoming messages are scored for prompt injection before your agent reads them. It works through SDKs for Node.js and Python, a REST API or an MCP server, so coding agents like Claude Code and Cursor can use it directly. A test key runs the whole API without sending real mail. The free plan covers 3,000 emails a month with no card; Pro is $20 a month and Scale $99.
