Mailing Lists and Targeted Messaging
Mailing lists provide an easy method of communication among groups of people. Instead of typing hundreds of addresses, you can simply type one, and all those subscribed to the list will receive your message. There are a variety of options, please see below.
All lists are subject to the Yale University Information Technology Appropriate Use Policy into and without reservation. Potential owners and subscribers must read this policy. List ownership or subscription constitutes an agreement to abide by Yale University policy. Lists which are not maintained properly, or which breach the University Appropriate Use Policy may be suspended or closed.
