Really good idea, given that they *probably* are on their summer breaks. Some won’t check work emails. Or wouldn’t know to expect the email and may miss it.My DS emailed his teachers and the counselor first to ask them if they would be willing to write the recommendations, and if so, which address, email, and phone number they would like is to list for them (which usually was the school info). As a courtesy, before we supplied their contact information, we let them know whom to expect emails or recommendation requests from.
What about phone numberSchool address and the recruiter in charge of your application should send it to them.
