If your database contains incorrect email addresses, this disadvantages you in two ways. First, you have to put up with annoying 'undeliverable' messages. And second, you lose the ability to communicate by email with your contacts. Email Verifier checks the validity of your email addresses without actually sending messages.
eMail Verifier 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.
Once you have verified your list you have the choice between saving the valid addresses and send your message directly to it or saving the bad addresses in order to clean your original list (recommended). In fact, if you use Maxprog Bulk Mailer, you can name your file "DELETE" or "UNSUBSCRIBE" and drop it over MaxBulk Mailer recipient list . All addresses from the file will be removed or unsubscribed from the list in a snap!
