I am PhD applicant in mathematics. One of my recommender refuses to make an account on webpage for recommendation submission and he wants me to find a way to submit it via email.
Is this okay and possible? I know some schools require recommender to fill out the survey when submitting the letter. Will this hurt my application? Whom should I email to? a graduate program assistant or graduate program director? How can I politely ask about email submission? I know they are receiving many emails from applicant so I don't want to be another burden but want to make the process simple so that my recommender don't get frustrated again.
P.S.: also some school explicitly said on their webpage that they do not receive rec letters submitted by email. In this specific case, what should I do? I don't have alternative recommender and the deadline is approaching.
