Different phishing scam email
Actually, it might not be.

Those who have been invited into the test really need to read the first e-mail, so that they know to expect and ignore the “your info has been reset” second e-mail. But if that e-mail didn’t reach you, I can understand your confusion. So please read the thread linked in the post immediately above and that may explain things.
I believe this is not phishing, but part of the invitation and enrollment system for Edge of the Mists testing, but you are wise to be cautious and delete, as anyone should for an e-mail that requests confirmation of a process that the player did not initiate.
After all, if your credit card company wrote and said “Your account is now in the hands of Thadeous the Thief, please click to confirm” you’d delete (and not click) in a New York Minute, right?
