Mailing Lists

A list can be used as a contact address that directs mail to one or more individuals who handle inquiries for a larger entity, or as a distribution list to communicate with a larger group. CUIT provides mailing lists and Google Groups/Collaborative Inboxes for Columbia departments and recognized clubs.

Note: All CUMC clients must contact their CUMC IT Support Desk for new mailing lists requests. Learn more by visiting the CUMC mailing list webpage

Grouper Mailing Lists

A Grouper mailing list is created by CUIT, who will assign one or more individuals as administrators based on the request. The list administrators can then manage membership using the Grouper web application. Grouper mailing lists are best used for smaller lists with fewer than 30 recipients. With Grouper, you cannot manage who can send mail, there is no mailing list archive, and there is no automatic handling of subscribing.

Managed Mailing Lists

Managed mailing lists provide more features than Grouper lists, such as subscribe/unsubscribe functions, archiving, and moderation. Lists are run using the Mailman software package and owners can use a web page interface to do list management. Once CUIT creates a managed list for you, you will be able to manage a number of features yourself.

Simple Mailing Lists

Simple mailing lists have been replaced with Grouper mailing lists. You should now request a Grouper mailing list instead. All Simple mailing lists will be converted to Grouper mailing lists during the last two weeks of January 2017.
