LISTSERV is an email list management software program that makes it easy to manage electronic mailing lists. It handles the tasks that would take hours or days to do manually, in seconds.

It’s been used since 1986 to let people discuss ideas, stay in touch, and share information. Groups of people — universities, interest groups, even politicians — use LISTSERV lists to communicate with each other.

People often refer to any group email discussion tool as a Listserv, even though the term is actually a trademarked name owned by the company L-Soft international, who built one of the earliest Listserv programs.

A hybrid Listserv allows you to keep your existing discussion, moderation and list archive features while adding the powerful database, targeting and analytics capabilities of LISTSERV Maestro. You can also create responsive landing pages directly in Maestro, and track subscriber activity on those pages for a fuller picture of your email marketing results. Using this information, you can tweak your messaging based on what works.


LISTSERV Maestro is the most advanced email marketing software available for managing and delivering communications with your subscribers. Its powerful tools and tried-and-true delivery process will ensure that your messages reach the right people at the right time.

Subscriber accounts are uniquely associated with a list group, which carries important system information including the secure hash of each subscription password. This means that each list in a list group can have its own public subscriber website and each subscriber can be separately identified by his/her unique subscriber account.

In addition, each action that can be triggered externally has a special download security token attached to it (see the description of each action for details). This token needs to be entered on the screen when accessing this URL in order to trigger the specific action. Only users who are in possession of this security token can actually download subscribers using this method. This prevents unauthorized users from downloading your list groups’ subscribers.


Whether you want to host your own LISTSERV instance on your servers or use our hosting services, the software can be configured to meet your specific requirements. There are benefits to each, but the decision ultimately comes down to your own unique circumstances and budget.

The first LISTSERVs were invented in the 1980s and allowed groups of people to discuss topics online, such as universities, interest groups and political organizations. They continue to be popular today, especially among politicians and businesses who use them to stay in touch with their constituents.

When you send a command that refers to a global list, LISTSERV will search for all lists that have the same name. It will then send you a copy of those lists and, if the list owner chooses to do so, an index of all the messages that were posted to that list on that day. These large files are normally broadcast during the night, to reduce network traffic.


LISTSERV is a piece of software that runs group email discussion lists. It’s also a popular way to keep in touch with a community of people who share a common interest, such as a condo association, book club or religious group.

Each list has an owner who takes care of administrative issues. Some lists are open and allow anyone to subscribe, while others are closed and require permission from the list owner to join.

The list service is a free tool for UVM students, faculty and staff. A web interface allows you to maintain lists, manage users and set personal preferences including start page, experience mode and navigation styles.

If you are a UVM student, staff or affiliate, use your UVM ID and password to log in. Non-UVM affiliates can use their email address and password to sign in. If you want to stop receiving emails from a list while still being part of that list, you can send a message with the command NOMail.
