What do we validate?


Detect if user mistyped their email or someone trying to use random/incorrect email.

MX Records

We check if MX records exist. Missing MX records means email won't be delivered.


We ping the SMTP Server to validate whether the email exists. We do not sent email. This is the most important and tricky step.

Accept All

This is an Email Server configuration where all emails are accepted or at least pretends to accept.

International Email

API is capable to validate International Emails (Other languages) like Hindi (India), Russian, etc. Note: Cannot validate right to left written languages.


Detection of whether email is from popular free email service providers or professional (custom domain).

We rely solely on SMTP verification. Some free email providers like Yahoo, Aol, are all Catch All servers. We cannot provide the accurate status. Other providers like Gmail, Rediffmail are not catch all, so we can accurately verify them. Our best results are for professional email verifications.
