Edfinity allows students to send messages to instructors, which include direct links to their assignment (straight to the problem they were working on, their answer history, etc). By default, these messages go to the course owner and to collaborators with edit access to the course.
To opt out of student emails:
- Go to the course and select the Settings > Course Details tab.
- Deselect Allow students to email you. Note this will only disable emails from this course for your account. Other collaborators will not be affected.
