Decide’s Email Verification solution allows users to verify email addresses in real-time or in batch processing. We do this through our single and easy-to-integrate API. We identify invalid email addresses by checking the domain and the username of an email address.
1. Is this a well-formed email address?
Not Well-formed: Jfirstname.lastname@example.org
2. Does the domain exist?
Not Well-formed: Jsmith@gmil.com
3. Does the user exist at the domain?
