I assume this is a phishing attempt.

Howdy all!

Just talked to Evan about this and yes, it’s legit. Invitations have been sent out and you should have received more than one email about the topic. It’s imperative that you read all these emails so you know more about the process (and how it’s not phishing/spam/et al).

This email is legit, but like it says, if you’re not the one that changed the email address, contact support immediately (and change your password) because it means someone is trying to steal your account.

Precisely. If you did not initiate a change of e-mail address, please contact Support. However, if you were informed about the possibility of receiving this e-mail from a proven representative of ArenaNet, please review that communication for more information.
