What Are Email Discussion Groups?
An Email Discussion Group is a collection of people communicating online with each other by email through email server software specifically designed to foster communication and collaboration.
Email discussion groups help create communities, promote online discussions, and enable the sharing of messages and information by email with a group of people who have similar interests, goals or needs.
Normally, any member of the mailing list can submit an email message which goes to the entire group (unmoderated setting). The mail server forwards any message it receives to all people who have chosen to join (subscribe to) the discussion group. Members can respond and share feedback by replying to the message. In this way, a group discussion takes place online.
Email discussion groups were one of the earliest successful internet communication tools—popular even before the World Wide Web.
