Notify enrollers / students by email when course is updated


Was wondering whats the best way to notify only the enrollers of a course by email when i make an update to the course like adding a new section or unit? From what i dug around i found “Course Highlight Emails” but I’m not certain if that only notifies when first making the course only or not, and looks like a workaround from what I’m trying to do. (best would be an automatic system that send emails to all enrollers when an update is made)

Thanks in advance!
