As I am trying to reduce the email accounts that I need to check on a daily basis, I am unsubscribing from a ton of emails today and re-subscribing to some with another email address. Unsubscribe pages come in all shapes and forms. These ones are the best I've come across in my quest against inbox overload. Why? Because they make it easy for me to just change my email address or choose which newsletters I want to unsubscribe from.
I like this last one because it plays on my emotions. Almost made me feel guilty for unsubscribing. Almost. :-)
