About Emailvalidation

Emailvalidation.io provides a REST API for validating email addresses in real time. The API returns a JSON response for each submitted email containing fields such as SMTP check, MX record lookup, a "did you mean" suggestion for typos, disposable-address detection, a score, and whether the address belongs to a free email provider.

The service also offers a web-based email validation tool for uploading files and checking addresses in bulk, an email finder for locating professional email addresses, and a LinkedIn email finder available as a Chrome extension. Documentation and a Zapier integration are referenced on the site.

The API is aimed at developers integrating email verification into their own applications, with a free tier for initial testing before sign-up is required for continued use.
