This is a well known bullshit email. They are fooling you and haven't hacked shit. I got one, too and all spam I get in this one email address I use gets promptly reported to spam cop. This one email was used for PayPal, my bank, ebay and a few other high risk accounts, nothing more. So I think now that I've gotten a few spam emails in this one addy was probably due to some asshole at ebay I bought from. Either he sold my PayPal email address that he can see when I buy something, or his dumb ass gone done and got his contacts list jacked. So now this one damn email is on a spam list. And I've never got spam to that account.
Just ignore it. Don't respond to it or anything. In fact, with stupid crap emails with links which you should NOT open, use this site:

If you use Thunderbird, turn off image loading and HTML parsing or what ever it's called. Especially if you use PGP like I do. If you're using Outlook... LMUHAO.
