Comprehensive email validation and fraud detection

Email Intelligence API

The Email Intelligence API is designed to provide an extensive analysis of email addresses, helping businesses and developers gain deeper insights into the emails they encounter.

This API validates email addresses, checks their domain's DNS records, detects disposable or temporary email addresses, and determines if the domain belongs to a government or educational institution with enterprise-grade accuracy.

Free tier included, no credit card required. One key works across every API.
