Use your Notification Preferences to set how Canvas notifies you of course events -- ASAP (near real-time), daily, weekly, or never. By default, all types of notifications will go to your University email address, but you may also receive notifications via additional email addresses, text messaging, or web services.
Do I get a notification about Announcements I post?
You can choose to be notified as the creator of an Announcement. If you don't currently receive these notifications, update your notification preferences and choose your desired setting for the "Announcement Created By You" notification. (Choosing ASAP for that type of notification will send you an immediate message in your chosen channel -- typically, an email message.)
