Make it easy for me to unsubscribe please

I’ve had the same email address for about 10 years now.  As a result, it’s on a ton of mailing lists, marketing databases, and spam lists.  Google Apps does a great job on the spam, but I just spent the last 30 minutes unsubscribing from about 30 email lists.
Some were easy to get off of.  Kudos to 37Signals and Facebook.  Others were almost impossible.  If you’re an email list admin, can you do the world a favor and make it as easy as a single click to unsubscribe?

Please!!
