eMail Verifier is your powerful solution for the standard "message delivery error.; Email Verifier verifies every email address from a given mailing list, allows to determine 80-90% of "dead" email addresses.
It works on the same algorithm as ISP mail systems do. Addresses for email are extracted from a Domain Naming Server (DNS) and eMail Verifier tries to connect with SMTP-servers and simulates the sending of a message. It does not send the message though - eMail Verifier disconnects as soon as the mail server informs the program whether the address exists or not.
eMail Verifier is a very effective piece of software that can verify over 10 emails per second. It can verify single emails or huge lists. eMail Verifier is multithreaded, providing high speed verifying.
