MyEd: Inactive Users

Most of our parents are MyEd users and we try to keep the number who are not users below 3%. We spend a lot of time every week contacting those who have become inactive by not opening the app for a month, so that they can receive our in-app messages (we don't send texts at all to reduce costs). It would be really helpful if this inactive issue could be changed. For example, could the inactive time limit be removed completely, or could parents about to become inactive be sent an alert that they just have to tap to stay active? It would be REALLY helpful and save us a lot of time.
