I've gotten an email like this. I believe it was when I ordered the 70s, 80s, 90s Stuff Pack. In my case, the money had not been taken from my account and I simply placed my order again. Glitches like this can happen from time to time. I don't think findmyorder.com is spam. It's got the Digital River name and logo on it. They are the people who process EA's online orders. As long as you don't give any financial information, I think you'll be fine using it to check on your order. Also, check the email address the email was sent from. Does it look legitimate?
Also, I'm moving this to the Technical Help board because it's not really about University Life game play.
