Announcements allow you to communicate with your students about course activities and post interesting course-related topics. They are the Canvas equivalent of emailing the entire class.
Once you make an announcement, it is emailed to the entire class and also saved to the Announcements page on your Canvas site. Here is how to make an announcement:
1. Click the Announcements link.
2. Click the Make an Announcement button.
3. Type a title for the announcement in the topic title field , add content in the Rich Content Editor , and edit the announcement features .
4. Click the Save  button to post the announcement.
Note: You can also send announcements from your preferred email client by emailing the classlist alias. Classlist aliases follow the format of LAWemail@example.com where the #’s are replaced by the course number, section number, year and term letter. For example, a valid listname for a 2006 spring semester course number 999, section 001 would be: LAW999-001-06A@LAW.UPENN.EDU.
Emails sent to the classlist alias are distributed to the students immediately and archived on the announcements page in Canvas.
