How the verification works ?
  1. 1. Syntax Check.
  2. 2. Checks for the domain name existence
  3. 3. Checks that the domain has been configured to accept emails
  4. 4. Checks if the user(the part before @) exists.


Note :- Morphy Email Verifier desktop version cannot verify yahoo , hotmail , comcast and aol mailboxes but web version can verify all of the ISPs including hotmail comcast, aol and yahoo.

What is the accuracy of the verification process ?
Normally we get 98% accuracy rate. Sometimes the recipient’s ISP reports a false positive (i.e. says the user exists but actually it does not) . Since we use several layers of verification we are able to correctly determine the status of an email address in almost all cases.
Will a real email be send to each contact to test?
No emails will be send to the contacts for verification.
