Are you one of those people who shares an email address with your spouse (like JohnAndAngela@email.com)? I don't understand why people do this at all. (Email accounts are free, after all, and even if you don't care about privacy, maybe your friends who are emailing you do.)
But if you're job seeking, you really should open your own account, with a name that doesn't sound like I'm emailing two people when I correspond with you.
Prohibitive? No. Slightly odd? Yes.
