Instead of taking the list of addresses and mailing in one go, Mail*Wiz individually formats each message, using the recipient's address, and personal name if given, and sends it. While this makes the delivery a slow process, and hence unsuitable for very large mailing lists, for any site that has a relatively small mailing list (say less than 1,000) this Dienstprogramm offers a very effective and time-saving alternative to normal mailing.
