The reengagement plugin provides a way for you to remind students to return to the course and complete activities.
The email is sent a specified period of time after a starting event, which may be enrolment in the course, or completing an earlier activity.
If the user has already completed the target activity, no email is sent.
You can also use this plugin to selectively release timed content in a course.
This plugin is developed by the Moodle Partner Catalyst IT
