What is Reacher?

Reacher is an open-source email verification API that allows developers to prevent bounced emails by verifying email addresses in real time before sending messages. This API, developed by Paris-based indie developer Amaury, connects directly to mail servers to validate email addresses. Reacher offers free usage for up to 50 email verifications per month, with paid plans available for higher volumes. The API can be self-hosted or used as a cloud service. Built in Rust using the Warp web framework, Reacher is designed for speed and scalability.
