Short answers is to make sure that $email is not changed or corrupted on the way from sender to receiver. There are attacks that does it such as "man in the middle".  Sender and Receiver both know the secret key ($mysecret). Sender sends data ($email) itself and message digest ($key). When receiver receives message he checks if data is changed or not by performing same operation $key = sha1($mysecret . $email); and comparing computed $key with the one he received. 
You need to research for further information. Search using "message authentication codes" or "message digest"
