Mails.ai is a transactional email API for developers and AI agents. It handles the everyday emails that apps and automated agents need to send and receive, like sign-in codes, receipts, order confirmations, notifications, and password resets, and it captures the replies as clean, structured data your app can act on. It is built for transactional, permission-based email: the messages a recipient asked for or expects. It is not a cold-email, bulk, or marketing tool. Emails are properly authenticated with deliverability handled for you, and incoming mail is checked for security threats before it reaches an AI agent. Developers connect in a few lines of code and can give an AI agent its own working email address in minutes.
Mails (mails.ai) has 19 customer reviews on The Fair Hearing, with an average rating of 3.0 out of 5.

Do not even think of using this rubbish. basic front end with highly poor system design. you will be blocked and blacklisted by ISP. we tried it for 2 months and its a complete failure. its a 1 man show so expect no customer services. send a message and they will never reply for days. arrange a call and you might get one guy calling himself "Jeff" but not a solution for a business. don't waste time.
