As an instructor, Banner allows you to email all the students on your advising page or on a class list at one time. You will see the email icons on each of these Banner pages.
Course email lists
With a single email address, course email lists allow you to broadcast messages to all students in your course. Registration for this list is automatically updated to match course enrollment throughout the semester. You can also add your TAs or other instructors as recipients or senders of email. This email list can be set up as an announcement list where only you can post messages (and others as you specify), or as a discussion list where students can also send email to everyone in the class. To send to your course email list(s), go to Banner.
Note: Once you go to your course in Banner, you must send the initial message from your brown.edu address, or from the address where your brown.edu mail is forwarded. After the initial message has been sent, you can use the list management tool at http://lists.brown.edu/ to add other e-mail addresses.
To add other list owners or moderators (such as additional instructors or TAs) to post to your list, see instructions here: Course Email Adding Users
Your brown.edu email is automatically added to your Canvas profile. Canvas will use this email to notify you of different types of events that happen in your course. You can add other notification types as well as adjust notification preferences. Read more at the Brown Knowledgebase.
To set up an email list for a group that doesn't have to be linked to course registration, Brown has a list server tool. Listservs allow you to easily manage opt-in email lists, such as email newsletters, announcement lists and discussion groups. The disadvantage of Listserv is that the list of subscribers is not automatically updated to match course enrollment. One of the list owners has to do that manually.
