I did a search on "iTunes scam" and the product name in your email "Co Pilot premium" and found this page.

Seems a lot of people are getting it.
I notice at the bottom of the email it says "If you did not authorize this purchase, please: Click here for Refund"
This is where the scam comes in.
When you go to the "refund" (scam) page they will ask for personal details and bank details so they can give you a refund (so they say).
If you fill this in then you have just given away lots of personal information including personal financial information.
If you get emails like this again just do a few Google searches on company name, product name and words like "scam" and you will find others have also got it.
