I have had a surprisingly easy time getting in touch with the senders to remove my address from their lists. I decided to tear off the address portion and contact portion of all the junk mail circulars that arrived in January. I discarded all duplicates and came up with four publishers so far.
Advo publishes ShopwiseNote: I called Penny Saver first (in December) and left removal instructions. Their outgoing message states that it takes them 2-3 weeks to purge you from their system, but I was still receiving their circular five or six weeks later. I called the same number and requested that someone call me back with a confirmation, which they did. I was told that they took me off on my first request, but that they use an "address card" that is separate from the circular. She told me that I am certainly not receiving that, and I should "inform the mailman" to stop delivering the circular. I taped a little note on the inside of my mailbox door addressed to Letter Carrier. We'll see if that works.
They have a web form. I filled this out and promptly received a confirmation postcard informing me that it could take 6-8 weeks to be purged from the system, and that the removal was good for five years, at which time I assume I will have to remove myself again.
