Applying to same companies for different positions over months/new email address?

Is it wise to create a new email address and submit applications using the new one after a period of time?

I've been applying for different job postings to the same 4 or 5 big aerospace companies for the last year. I have more experience now, so my resume is better than when I first graduated from college. I'm worried that I'm being looked over because HR sees my name/old email address and assumes I'm not qualified.

I'm not even sure this happens, but I'm hoping that I'm being considered each time I apply.
