When students submit an assignment via Turnitin, the student receives a notification of their submission and the tutor also receives a notification that a student has submitted to the assignment.
Unfortunately due to the fact that many tutors on college have teacher access to many course pages this can get out of hand. In this case it is often better to stop receiving these notifications. Fortunately there is an easy way you can do this.
Click on your name at the top right of Moodle
Select Notification Preferences
Scroll down to Turnitin Assignment Instructor Digital Receipt Notifications and select off for both online and offline under the email column.
