Electronic mail lists allow the massive distribution of messages to multiple users that are included in a list. Cobian Herald allows the management of these lists and of the address of each of the contacts included.
To start off, you will have to indicate the electronic mail address of the administrator, so as to know who send the mail, because Cobian Herald isn't a mail server, and will require external POP3 and SMPT servers to work.

Cobian Herald will revise the incoming mail every certain amount of time, and will check if the people that have received your messages have answered. It is very easy to use, and you will be able to modify your lists to your own liking.
