There are a couple of possibilities for why students might not be receiving your course Announcement:
- Course Status: Please make sure your site is published before sending or scheduling Announcements. Announcements cannot be sent from unpublished or concluded course sites. Canvas Guide: How do I publish a course?
- Spam Folder: The notification may have gone into the Spam folder of the students' email, so they may need to check there. Also, if students have email filters set up in their email application, it's possible that some messages may be getting inadvertently caught in that filter, depending on the filter's settings.
- Notification Settings: Students may have changed their default notification setting in bCourses, which, by default, is "Notify immediately" for Announcement postings and Inbox messages. Please keep in mind that students, as well as all users, have the ability to change the frequency of how often they’d like to receive Announcements, or any notifications from bCourses, by going into their User Settings — see Canvas Guide: How do I manage my Canvas notification settings?
While we can recommend to students that they leave their Notifications Preferences as they are, ultimately, each person decides how often and where they will receive messages sent from bCourses. Therefore, it is important to have a discussion and/or a written statement in your syllabus about your class communication policy so that, regardless of their preferences, they are aware of their responsibilities and alternate ways of contacting your and/or your teaching team should they experience any issues. - Delayed Notification: Notifications set to "Notify immediately" may be delayed by up to one hour. Additionally, to prevent users from being spammed by multiple notifications in a short amount of time, some notifications may be temporarily held in case an instructor makes additional changes — see Canvas Guide: Canvas Notifications.
