I got one today ostensibly from "youtube services" with the subject line "your video has been approved". I didn't upload a video, so I googled around and verified that it is a scam.
Be careful out there. If you get emails from companies that normally don't send emails asking you to click on links, don't click. You can go to their website directly through your address bar and find out if the message originated from them. Snopes.com is a good place to check whether anything is for real or not.
