Cross-language email validation. Backed by a database of over 55 000 throwable email domains.

  • Validate the format of your email (uses validator.js email regex underneath and FILTER_VALIDATE_EMAIL for PHP)
  • Validate if the email is not a temporary mail (yopmail-like..., add your own dataset to list.txt)

This will be very helpful when you have to contact your users and you want to avoid errors causing lack of communication or want to block "spamboxes".
