A mailing list is a distribution list that provides a way to communicate electronically with a group of people through one email address.
When someone sends an email message to a mailing list address, the mailing list server sends that message to the people currently subscribed to the list.
Mailing lists allow people to join, also called subscribe, or leave, also called unsubscribe, at any time depending on the list settings.
Example: If a list address is listname@lists.fau.edu, sending a message to that address can distribute the message to the list’s subscribers.
