Closed Beta In-game Mail?

Q u o t e:
One of my toons got a mail saying I am eligible for closed beta, and includes a link.

I was wary it was phishing/hacking since it didn't have a blizz icon in the mail, so I clicked on the Report Spam button. The mail vanished.

But then it came back. Is it legit? I thought it usually goes to the account email.

You might have gotten a second one - or you could have logged out and back in again before the item in question could be purged from your mail.

There are certainly no plans at this time to send notification of eligibility for the Cataclysm beta via an in-game mail.

Q u o t e:

I seem to remember there being some sort of glitch that makes the mail show up again instead of being deleted after they address the [Report Spam] side of it. If it's definitely the same mail (maybe check the days remaining), you can probably delete it if it shows up again.

Actually, please continue to use the Report Spam button in each case, in the event that the message arrived from a new sender =).
