My given name and my surname are both well-known given names. Hence, many people use my surname as my first name mistakenly. This occurs especially in mail conversations when I cannot introduce myself face to face.
Usually, I use polite and subtle ways to correct people, e.g., using "P.S.: XXXXXX is my first name. ;)". However, in the last few months the number of people addressing me by my surname increased a lot and it started annoying me. As an academic advisor, many students consult me using mail. I don't want to correct people all the time, especially in the consultation context, but I want to be addressed using my given name. I fear that my "wrong" name naturalizes among students and other members of my institute. It seems like the conventions "[given name] [surname]" and "[surname], [given name]" don't point out my given name sufficiently.
How should I deal with this problem? Is there a way to prevent people from confusing my first and my surname in the first place, maybe by highlighting it using a specific notation?
