Hi my fraternity is currently on the fast track to being a big fraternity on our campus, but we have a problem that I would see if yall have any suggestions.

Our nationals have a list of alumni that have addresses, phone numbers, and emails, but some of the alumni that we would like to get in touch with have not updated their profiles in awhile. Do you have any suggestions on how to try and update these contacts?
