The American Marketing Association (an organization you would think would have a handle on dealing with e-marketing) is driving me nuts. I originally had signed up for their newsletter and received it for a while, reading it with varying levels of interest. It became one of those in my in box that was surplus and so I unsubscribed.
Since then I have tried to unsubscribe several more times, each time it stops one of their various publications and announcements reaching my in box but apprently registers me for another!
I have finally (as far as I can see) unsubscribed from everything and so should expect never to see them in my in box again - I will let you know
