According to NCAA recruiting guidelines for high school juniors, coaches can phone, text, email, DM, and contact players via most private, digital communication channels. In other words, high school seniors who have been diligent in their recruitment should have a busy year ahead of them responding to college recruiters' letters. The only limitation on how often you can contact a prospect is whether it constitutes "impermissible inducements" under the law. For example, if a coach tells a player that he or she will be given a full scholarship if they attend a certain school, then that is an impermissible inducement and can result in jail time if reported by the player. The same goes for any promise of academic credits, on-campus housing, or other benefits that are not available to everyone. Generally speaking, recruits can be contacted no more than five times per year. It is important to note that just because you can contact a prospect does not mean that you should. If a player doesn't want to be recruited then it isn't worth your time to pursue him or her. Also remember that the more you contact a prospect the less time there is for him or her to respond positively. High school players need time to think about what schools are interested in them and make a decision about continuing their recruitment. Do not call or write repeatedly if all you want is for them to tell you yes so you can move on to the next prospect.
