YL Mail Verifier verifies every e-mail address from a selected database or mailing list, allowing you to determine up to 90% of “dead” mail addresses. After loading your mailing list for a cleanup, YL Mail Verifier starts verifying each email address for validity. All addresses are checked in the multithreaded mode, which speeds up the entire process. Three steps of verification include:
E-mail address syntax check
During this step, YL Mail Verifier marks invalid such addresses as username#gmail.com, john!@$gmail,com, etc.
The availability of e-mail domains
During the second step, the program checks the availability of domains, i.e. it marks valid such addresses as user#yahoo.com, user#hotmail.com and marks invalid any nonexistent domain (for example, user#hhfdjggyt1.com, user#jhhfuyq1lj.biz)
The existence of e-mail addresses on their mail servers
During the final step, the program tries to establish an SMTP connection with the mail server and checks each email address for validity there.
