1st Email Address Verifier (EAV) is a program that
verifies the validity of e-mail addresses in mailing
lists.The program works on the same algorithm as ISP
mail systems do. Mail servers addresses for specified
address are extracted from DNS. The program tries to
connect with found SMTP-servers and simulates sending
a message, but does not send the message out. EAV
disconnects as soon as mail server informs whether
this address exist or not. EAV can find about 90% of
dead addresses - some mail systems receive all
messages and only then see their addresses and if the
address is dead send the message back with remark
about it. 1st Email Address Verifier can save time and
money for businesses who send newsletters to their
clients, nonprofits who send bulletins to their
members, or any person or business that needs to
maintain a clean e-mail contact list. It supports to
save verified result to Text, CSV, TSV and Microsoft
Excel files. Allows you to save successful or failed
email addresses to separated files, it supports to
remove duplicate email addresses automatically.
