We hear this almost every day. They tend to target new sellers just hoping you will get excited and not know any better. Unfortunately, these scams are becoming very common, not just on Etsy, and they will only get worse during the holidays. If you haven't already, run a virus scan on your computer, and change your passwords everywhere, not just for that account.
When you get an email like that, don't click any links in the email because that will go to a fake site that looks like the real one, where they will try to steal identity or financial information. Instead go to the real site the way you always get there, and look to see if the notice is in your member's area. If it isn't, it is probably a scam.
Etsy will never ask for your email because they already have it. Anything from Etsy should be in your Messages folder under the From Etsy tab. If it is a real sale, it will show in your orders page.
