API Documentation

Keeping your email lists clean starts at the source. The EmailVerify.io API lets you verify email addresses in real time, ensuring only valid contacts enter your system. With easy integration and detailed results, you can build applications, forms, and workflows that maintain accurate lists from day one.

Our fast, reliable, and developer-friendly API supports everything from validating a single signup to enriching an entire contact database.

• role_based: Functional accounts (support@, info@)
• do_not_mail: High-risk addresses to avoid
