Yes, to me it seems arrogant. So does “onthestage.” It comes across as “look at me!” Most likely your email address doesn’t matter but I always error on the side of being professional.
I would choose something witty and clever. None of these are witty or clever. And so sound pushed.
It will be hard to think of something witty and clever–which is why it’s called “clever”–but if you can do that, then it will make reading your handle a good experience for others.
Since you’re interested in theater, how about adopting and adjusting a Shakespeare quote of some sort? for example.
I would use something professional like FirstNameDotLastName@gmail.com. I think it’s helpful to get your full name in front of people as often as you can. It’s not so helpful for them to have to say “Sally who?” whenever they talk about you.
@NotLeviosaaa - If you are primarily concerned about separating all of the college correspondence from your other emails, make your new account with a different service than you normally use. For example, all the college stuff could be going to firstname.lastname at Yahoo, while your regular professional account is firstname.lastname at gmail.
You received two good suggestions… First, use separate servers for personal versus admissions or business emails. Second, use your name for your email by using your first and last names. Make up very unique password using something very personal such as grandparents phone when you were small with your first dentists initials or team colors in elementary school. I like going very personal combined something really remote. Use the same or similar passwords and stow a copy in a unique place like a Bible or favorite child’s book.
Third reason for a formal email address. Someone from the admissions office may need to reach quickly. Sorting through lots of addresses to find you is a problem when the name is too unique. If I needed to reach you, I would so prefer sally.jones.
