I occasionally deal with being mis-gendered as female by clients at work with whom I only ever correspond with through email. Since their only interaction with me is seeing my name, Alister, and the tone of my message, I'm actually somewhat confused about why this happens so often. (Is Alister sometimes mistaken as a traditionally female name??) I actually AM transgender, however, so I'm rather used to correcting people face to face, although it happens very infrequently now if I'm meeting with someone in person. The problem only seems to occur through email.
I've just had someone respond to an email with "yes ma'am" and don't know how, or if, I should correct her. Is there a professional way to bring this up, or should I just disregard it and hope that it doesn't cause problems down the road if, say, we have to have a phone call?
