I just received an email, purportedly from ZoneAlarm, headed "Last Chance to Save - Summer Heat Sale ends Tuesday 7/30!". Is this really from ZoneAlarm? According to the ZoneAlarm Terms and Conditions, I can unsubscribe from such emails by clicking on the "Unsubscribe" link at the bottom of the email. There is no such "Unsubscribe" link.

Does the lack of this necessary link show that this is a fake email of some kind?

If not, how do I unsubscribe from these spam emails? I've not used ZoneAlarm for years, but it appears I still have an account - I successfully logged in. However, once in, all I got was a "Web session expired" notice, "please proceed with purchase ........." - what purchase? Nightmare.

ZoneAlarm website seems to have me trapped in an endless loop.
