Google Apps decides to include me in this email because some random person has decided to use my email ID as part of the sign-up. I keep getting these messages and I have no way to unsubscribe.<p>At least in other Google emails, there will be an option to disconnect but this one doesn't have it. The fine print at the bottom says this is 'mandatory'. I know I can apply a filter to get rid of it but that's not the point.
