Three steps of verification include:

E-mail addresses syntax check. AMV marks invalid addresses such as bill#yahoo.com, kate!@$aol,com etc.
Availability of the domain of e-mail addresses. AMV checks the availability of the domain, i. e. it marks valid such addresses as bill@yahoo.com, kate@hotmail.com and marks nonexistent domains as invalid.
Existence of e-mail addresses on their mail servers. AMV tries to establish an SMTP connection with the mail server and tests the addresses.

To verify each email address in the list you may complete all the steps or only some of them.

For example, if you have a huge mailing list with hundreds of thousands of addresses then you only need to do the first two steps because checking each address on its mail server takes much time. This type of mailing list verification usually removes one third of all "bad" addresses.

If your mailing lists has several thousand email addresses then you may complete all the steps of verification. All three steps guarantee removing most non-existing addresses.

Atomic Email Verifier is fully integrated with other Atomic e-marketing tools. So, you can collect the email addresses using our email extractors (e.g. Atomic Email Hunter), transfer gathered emails to AMV to remove obsolete addresses and then use our bulk emailer - Atomic Mail Sender to send out mass mail. Optionally, Atomic Subscription Manager can automatically manage the mailing list and track all subscription instructions.
