Wierd Email

Unless the body of that email had something important in it I would have to say it is most likely a spam or spoofed email and may have even had malicious content embeded in the headers or body and your email client stripped and blocked parts of the email of that content resulting in you seeing all of the normally hidden content.

The snip you posted looks like a crummy commercial for something like a program or app as it mentioned googleplay and appstore..
