I was one of the recipients of that T&Cs e-mail. As I recall, it listed British residency and having flown upper class as conditions. As of this morning, I'm still Gold, and I received my credentials last week. FWIW, I had transferred some points into my account before receiving the T&Cs e-mail.

Also, if you've still got the status, you may want to consider trying for a status match with someone else before they yank it. I was able to get one by sending in a printout of my account information page showing Gold. YMMV.
