If unmoderated, all messages immediately get sent to everyone on the list. If moderated, messages first go the list moderator who must approve the message before it is distributed to list subscribers. If a subscriber sends rude or unsuitable messages, list owners can destroy the messages and, if they choose, remove that person from the mailing list. Mailing lists can be configured to only allow subscribers to send messages to the list. This is useful if you wish to avoid spamming on the list.
Mailing lists allow for immediate delivery to subscribers.
Disadvantages Some mailing lists generate a considerable amount of e-mail, which can clutter up your mailbox. Subscribers have to regularly take time to read the messages and delete those that don't interest them. If you subscribe to several active mailing lists you could quickly reach the mail quota enforced on Netinfo and Interchange. If this happens, you could lose your ability to receive new e-mail until you clean up your mailbox. For this reason, it is a good idea to unsubscribe from mailing lists before going on vacation.
