Over 55% of Catalog Choice members are opting out of a catalog mailing because they either prefer to shop online or they want to help the environment. Another 40% are making the request because they have no interest in the products of the given catalog. These survey results are based on responses from over 6 million surveys.
I think the 40% indicating no interest in the products says a lot about how bad direct marketers are in “guessing” people’s desires. Seems like after decades of trying they still aren’t much better than a coin toss :-)
