Atomic List Manager can split and merge email mailing lists containing multiple data parameters. Our mailing list software can split the list using some common-sense filters, like excluding invalid and duplicate e-mails as well as free e-mail addresses (Hotmail and Yahoo!, for example). A number of "mix-and-match" and filtering tasks can be done with Atomic 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, and can add the name string to it automatically. Plus, the program can purge the list of "suspicious" e-mails, like NULL@, REMOVE@, SUBSCRIBE@, UNSUBSCRIBE@, CANCEL@, NEWSLETTER@ etc.
