The email that you received and depicted in that screenshot is a fake/scam.
This is a 'phishing' website, pretending to be a Blizzard site asking for your username and password for "log in purposes". Instead, upon entering your information here, it will save the information and give it to the creators of the fake website, granting them access to your account.
Please be sure to note that
we have not started the Wrath of the Lich King beta program for public play, only the opt-in for a
chance of winning access to the upcoming beta. More information about this opt-in can be found here:
