Definitely phishy.
I can only repeat what I said in another thread: Customer Support is not sending out warnings that accounts will be suspended or terminated. If we need to block an account, we just do it without any warning.
Gailes Post in this topic suggests a change in that policy, though.

This e-mail and I’m flagging this one only it not a phishing attempt. It’s a legitimate e-mail from one of our CS Agents. Please continue the discussion in the e-mail, as this is not a suitable topic for the forums (for your privacy if for no other reason).
Thanks.
Gus, who is part of our CS team here at ANet, did create a support ticket for the player (ie send an email). That player posted the email in the thread mentioned. And if you are reading the message thorough enough, then you realize that it is not quite a warning that we are going to block his account. It is more a request to stop certain actions. As you may also notice, we did not request ANY sort of personal or account information, or action from that player, except a simple email reply. Please note that we also did not send a link either. And as I said, when Gus sent this message, a ticket in our ticketing system was created for this customer.
I want to point out that this message was an unusual exception and probably will not happen again. We are not changing our policy in that regard. However, there can always be very unusual circumstances which call for a brief deviation from our policy.
To reiterate what I said earlier, we are not sending warning emails about accounts being blocked, we generally speaking just block the accounts without any notification.
Hope this helps to clear this up a bit.
