If you are simply looking for a simple bulk e-mail solution, you may not need the extra functionality (archives, subscription, etc) that LISTSERV provides. If you need a small, internal group communication list, you can request an Active Directory (AD) group.
An AD group will allow you to send to a group of UT users using a single ‘firstname.lastname@example.org’ address
To request an Active Directory group, contact the HelpDesk at (865) 974-9900.
LISTSERV is a system that makes it possible to create, manage, and control electronic mailing lists on the UTK network or on the Internet. A listserv may be used for sending individual announcements or for group discussion among subscribers. Discussion can be archived for later viewing.
While LISTSERV use is free, there is a $50 fee to set up your LISTSERV.
When a LISTSERV is public, it is listed in the email list at http://listserv.utk.edu. Public users can freely access the LISTSERV’s page and subscription options.
Private LISTSERV’s are used for internal lists that aren’t available via the public website. Use private LISTSERV’s when you want to set up your own subscription to the list.
LISTSERV’S can be moderated by assigned owners and moderators and be private or public.
Owners may approve and add subscribers or allow potential subscribers to join the list themselves.
