What’s the difference between a discussion and an announcement list?
Discussion lists:
Discussion lists, on the other hand, are more like forums – while one person may start the conversation, list subscribers are all able to contribute and reply to everyone else on the list.
Email that is sent to the list will then be distributed to everyone else on that list via a moderator. For a large list, this may mean a single message being re-distributed to several thousand people, so it’s worth thinking about what you put in your message and only including as much of the message you’re replying to, if necessary.
Announcement lists:
An announcement list essential functions like a newsletter – information is distributed in one direction to people who are subscribed to the list. They are used for breaking news, announcements and special offers, campaigns etc.
