I DON'T BELIEVE THIS

My brain must really be in a coma. I've updated my resume so that it's in tip top shape to hand out to possible employers, but like a week ago when I tried emailing my resume for a summer internship I came across a problem. I listed what I thought was a functioning email address, but to my surprise it's not. Apparently it's just to use as an identity when I log onto my email account. It doesn't function as an email address. Am I right? Please someone tell me if I'm wrong. I've passed out my resume to a few companies at a job fair and now I feel so stupid because I gave what I thought worked as my email but it doesn't. No wonder why my inbox has been empty lol!
