I would also suggest even if you aren't looking for a job and contacting a government agency or any profession, to use a decent email. I work for the state and we get all kinds of odd email addresses asking for information (we license professionals). I've gotten the sexykitty type emails and it's difficult to take them seriously. Also, sometimes when it comes through, it will be highlighted (if doing any contact through email) so if you use an _ as part of your email, it can be missed. 0 vs o also difficult sometimes to tell the difference. 1 vs l also. (the 1 vs l looks very different on here but on my email server, they are similiar).
I have to also agree with a pp, those who use another person's name, I'm thinking I'm not talking to them but to another person.
