Mails.ai

Self-serve AI email API for agents. Drop ~6 lines into your agent program — it gets a working email address with parsing, identity, and reputation built in.

A real address in one API call — send, receive, reply. Every sanctioned agent path stops at a draft — Google’s own Gmail MCP ships eleven tools and no send. Not a setting you can forget to switch on, and not a clause in an acceptable-use policy. Every inbound is scored for prompt injection and flagged before your agent acts on it. The email leaves the scanner as data — injection score and sender reputation on every event, intent and entities when you opt in.
