Yes I got that one about 6 months ago and did not do a thing about it. My thought was If "they" contacted me then "they" must know my account is active and if "they" would just look at all the activity that goes on with my account "they" would not be sending be this "letter". I believe I sent it to the scam link on Hotmail, too.
So many dishonest people out there anymore. :-(
