The default notification setting for Announcements and Conversation Messages are “Notify me right away”. However, students have the ability to alter the frequency of how often they would like to receive notifications, including “Do not send me anything.” We recommend telling your students to leave these notifications on “Notify me right away” in their personal settings. You can also include in your syllabus that students are responsible for receiving communication by teaching staff. Please note if you posted an announcement BEFORE the course site was published, the notification did not go out, since unpublished courses do not generate any notifications.
For instructions on how to set up notifications, see the step-by-step guide below: https://community.canvaslms.com/docs/DOC-1286
It is also possible that the notification emails are going into a student’s spam folder. Please have them check there as well. If you have a particular student reporting the issue, please email us at firstname.lastname@example.org with the student’s name and which announcement/message they didn’t receive and we can investigate.
