Plus, the program can purge the list of ?suspicious? e-mails, like NULL@, REMOVE@, SUBSCRIBE@, UNSUBSCRIBE@, CANCEL@, NEWSLETTER@, ACCOUNT@, MAILER-DAEMON@, BOUNCE-MAIL@ The program can process mailing lists that contain multiple data parameters, like in em@atompark.com, Evgeny Medvednicov, 23, AtomPark Software gates@microsoft.com, Bill Gates, 48, Microsoft Corp A number of ?mix-and-match? and filtering tasks can be done with List Manager based on parameters other then e-mail address.

For example, the program can personalize mailing lists.

It finds an entry that has both an e-mail address and a name (as in ?John Smith? jsmith@e-mail.com).

If the program locates the address jsmith@e-mail.com, it can add the name string to it automatically.

Another great option is a ?repair e-mail? feature.

Frequently, users misspell part of e-mail address, when entering it.

The program employs a unique algorithm that tries to repair invalid e-mails and checks the validity of the ?repaired? version.
