By default, instructors in a course will receive an email every time a student makes a Turnitin submission within Moodle. If you'd prefer not to receive these emails, you can adjust your settings to stop any emails. This is a Moodle-wide setting and will affect all of your courses.
Instructions
To change your notification preferences, click on your initials on the top right of any Moodle page → Preferences → User account → Notification Preferences. Scroll down to the appropriate sections for Turnitin Assignment 2 and Turnitin plagiarism plugin and click each option to set them all to "Off" to prevent emails being sent whether you are online or offline.
