What to write for subject when contacting potential supervisor? I am trying to contact a potential supervisor about doing a master’s by research. I have already wrote my email by I am unsure about what to write for the subject box of the email. Different people have advised me on different things and I am unsure what do. Does anyone know what is a good subject line?
When I was applying for PhD, I used "prospective graduate student" as a subject line, which was quite sufficient. If your potential supervisor accepts students for different programs, you can specify the degree you are seeking (Master's) in the subject line. 

The rest of the information (your background, interests, etc.) should be in the email body. 

Good luck :)
