Most online training is self-paced, but many institutions expect Learners to complete that training.  Currently, the system enables Admins and Instructors to send a custom reminder message after X days of inactivity.  However, it does not enable you to send additional reminders should that user remain inactive.

You offer the ability to schedule multiple custom messages off the inactivity trigger, but those messages cannot be turned off should the user become active in the course.

Providing the capability to stop inactivity-triggered messages that are on a X-day delay would enable Admins and Instructors to set up a multi-touch campaign that will help to boost activity and overall completion rates.
