1. Disabled notifications
The default notification setting for Announcements and Conversation Messages is Notify immediately. However, students can adjust the frequency of notification emails, including Notifications off.
We recommend instructing students to leave notifications on for these two categories, particularly to Notify immediately. If you plan to utilize the Announcements tool, you can make it clear in the course syllabus that students are responsible for receiving communication by teaching staff, including Announcements from Canvas.
2. Delays due to high traffic
Canvas can experience delays in sending notifications when there are extremely large message queues, especially during the start of a quarter. You can check Instructure's Status page to see if there are any performance issues.
For time-sensitive messages that must go out at a time Canvas is experiencing delays, emailing students directly instead of relying solely on Canvas Announcements is recommended. Student email addresses can be downloaded through Roster Photos.
3. Emails in Spam or Clutter folders
It is possible for notification emails end up in a student’s spam folder. Student scan add firstname.lastname@example.org to their address book to help prevent emails from going to spam.
4. Course is unpublished
Announcements posted before the Canvas course shell is published do not generate notifications. Notifications do not go out for unpublished courses and are not queued up to be sent once you publish the course. If you have already posted the announcement and your course is not yet published, publish the course (once it's ready to go live to students) and then use the Delay posting feature to trigger another notification.
5. Specific students didn't receive a notification
If only one or a handful of students claim they did not receive a notifications, it's possible that their email address was added to Instructure's suppression list at some point. Students can check to see if they are part of this list by following the steps below.
- Click on Account > Settings
- An exclamation point next to the email address means Canvas has tried to send an email to the address but it failed.
- Hover over the icon to read the error message.
- Students should contact email@example.com if their email is on the suppression list.
