I am currently a master's student outside the U.S., and I plan to contact professors in U.S. universities for PhD applications. I have a bunch of email addresses available, and I don't know which one is the most appropriate for communication.
My main objective is to make sure my email doesn't get lost in the spam folder, and a decent first impression would not hurt.
email@example.com: Email given from the current institution where I attend.
firstname.lastname@example.org: Alumni email from the university where I got my undergrad degree.
email@example.com: Email from a well known U.S. university where I spent a year as an exchange student.
firstname.lastname@example.org : Private email address
My question is, do you think the possibility of getting a response depends on the email domain? What email domain should I use?
A friend of mine who ended up at a top-5 grad program suggested me to use (3), saying that it could increase my chances of getting a response. However I am cautious that it may look pretentious or delusional, considering I had been there some time ago.
Am I overthinking this?
