Before you begin

The person (or account) who creates a new IU List mailing list is the list's privileged owner. Lists may have multiple owners and moderators, but only privileged owners with a valid University account can rename or close a mailing list.

Each list should always have at least one privileged owner with a valid University account. A list without a privileged owner with a valid University account is considered inactive, and if a new privileged owner is not set, the list will be removed, see About inactive IU Lists.


If an IU List mailing list has had no correspondence activity for at least 18 months, or if the list has no privileged owner with an active University account, it is considered inactive; see About inactive IU Lists.

As the owner of a mailing list at Indiana University, you have full responsibility for actively monitoring and maintaining the list. The subject matter covered by the list is up to you. By agreeing to own a mailing list, you assume the responsibility of day-to-day monitoring and operation of the list. It is your job to ensure that the list continues to run smoothly and that all participants adhere to university policies and follow the list's stated objectives. You will be expected to subscribe to the list and monitor the discussions to ensure that the list is serving its intended purpose.

As a guideline, IU List mailing lists should have no more than 30,000 subscribers; also, the more active the list, the lower the number of subscribers should be. To ensure mail delivery, the IU List system administrator may throttle any list that causes excessive load on the mail relays. If you need to send communications to more than 30,000 people, you may want to consider using Salesforce instead.

To request a new mailing list:

  1. Go to IU Mailing Lists.

  3. In the upper right corner of the screen, select +Request a List.
