how to address a professor in email
1 If your professor signs the reply with a first name, it is still best to address him or her as Dr. Last-name or Professor Last-name in an email. 2  Do not use the professor's first name unless you have been explicitly invited to do so. 3  You should also be sure to spell your professor's name correctly. Make use of the professor's office hours-you can phone and/or show up-and most likely get an immediate response. 2  Or, if the office hours don't work for you, make an appointment to visit either by phone or in person at another time. 3  Reserve email for short exchanges.
