Reacher

Reacher is an open-source email verification API that is suitable for both personal and professional use. The solution promises world-class email verification technology that brings down bounce rates in real-time. Moreover, as a stateless solution, Reacher is an appropriate choice for horizontal scaling technologies, enabling businesses to restrict spam sign-ups on their websites and clean large lists on the go. The Rust programming language, based on the Wrap web framework, makes the software run appropriate email verification campaigns with speed and gain adequate results accordingly. The fully-featured portal does not rely on historical data to provide adequate results; it connects with the businesses' mail server in reality to check out the availability of the mail. The software looks out for hard bounces, MX records, SMTP, MTA, disposable emails, catch-all, and role-based accounts accordingly. Reacher also has a powerful REST API of its own alongside a JavaScript SDK that can perform email verification in bulk. Privacy is fully guaranteed
