Why Use an Email Validator?

Our email validator cleans your list,

enhancing marketing and boosting clicks.
Real-Time Validation

Verify if an email address is valid and active within milliseconds via the API. This helps you catch invalid emails before they hit your database or mailing list.

Spam Trap Detection

Automatically detect throwaway email addresses and known spam traps. Removing these keeps your list clean and protects your sender reputation (no more emails going to blackholes or spam honeypots).

Catch-All Domain Handling

Recognize domains that accept all emails (catch-alls) so you can flag or double-check those addresses. This prevents false positives and lets you handle uncertain addresses appropriately.

High Accuracy

Enjoy 99% accuracy in verification results, so you can trust the API's responses when cleaning your email list. Fewer false results mean more confidence in the emails you keep.

Easy API Integration

Developer-friendly REST API with clear documentation and examples. Get up and running quickly in any language or framework without unnecessary headaches.

Email Finder

Provide a name and company domain, and our AI-powered system will find the correct work email if it exists. This is a handy add-on to grow your contact list with verified emails (seamlessly integrated into the same API platform).
