This is information that you've specifically asked us to tell them about, so we are happy to do it. And unlike most information that direct marketers pay for, it is under your control, and it influences them to behave in the way that you want them to. Some people who want to receive absolutely no solicitations are surprised that direct marketers might pay to learn this fact. But there are two good reasons why. A piece of junk mail costs more than a dollar on average, and if you just toss it away the sender has wasted a dollar.
Direct marketers are the greatest economic rationalists in the world.
When they hear a sales pitch, they know exactly how to cut through the puffery and sweet-talk and get straight to the value being offered, because that's the business they're in. All that matters to them here are whether they can save money by not sending their mail to people who wouldn't buy, and whether they can find more people who are interested in their products. These are the reasons they will decide to work with us, not because we tell them we love them. If our tone sounds slightly mocking at times, that's only to point out in a less monotonous way that the methods that direct marketers have had to use in the past could be improved. You don't seem to be maximizing your gains.
