What is Reacher and how does it function? Reacher is an email verification API that is open-source and can be used for personal and professional purposes. It uses advanced email verification technology to reduce bounce rates in real-time. Reacher is designed to be compatible with horizontal scaling technologies, making it a suitable choice for businesses looking to prevent spam sign-ups and clean large email lists. The software is built on the Rust programming language using the Wrap web framework, allowing it to efficiently run email verification campaigns and provide accurate results. Unlike other solutions, Reacher does not rely on historical data but instead connects directly with the business’s mail server to check the availability of each email. It checks for various factors, including hard bounces, MX records, SMTP, MTA, disposable emails, catch-all accounts, and role-based accounts. Reacher also offers a powerful REST API and a JavaScript SDK for bulk email verification. Privacy is ensured with Reacher’s GDPR compliant features.
