DS’s high school and teachers did nearly all their communication through email. 9th grade was ROUGH for DS while he adapted, but finally as a senior he’s pretty good about at least keeping up with his school mail.
The big regret I have though is not creating a completely new and shared account just for college stuff. Right now it’s going to his non-HS account which also gets a ton of other junk because he uses it for signing up for everything. Between that and all the spam college emails it really is a PIA to find pertinent emails. I’m glad several of the portals of the schools he’s been accepted to keep a record of messages sent out.
