There are indeed phishing emails in circulation right now that mimic
World of Warcraft: Cataclysm closed beta invites, and players should always remain cautious when responding to or clicking on links contained within emails that appear to be sent from Blizzard Entertainment.
That said, players who are selected to participate in the beta will receive a notification email. While the email itself isn't necessary for beta access, it does contain more detailed instructions for installation, common troubleshooting steps and helpful reminders, and customer support contact information—useful bits of data to have. So, be sure to double-check that you're not reading real email from Blizzard Entertainment before clicking that "delete" button. (If you're unsure how to tell a legitimate email from a phishing email, here's a good guide to reference:

You are definitely correct, though, Elbeghast. Players who are invited to the
World of Warcraft: Cataclysm closed beta will be able to tell by visiting their Battle.net Account Management page and checking the available licenses under the "Manage My Games" section. :)
