Apparently a Canadian ad agency did this for a Porsche dealership some years ago, and the campaign is often hailed as a success in the marketing world because a lot of people went to the website listed on the card. In marketing, mailers almost always get under 10% response rate- some hover between 2-5%, and this campaign got 32%.
But, to me, the idea seems really intrusive, and would be a guarantee that I'd never do business with the company. I might check the website to see who the heck was at my house (which for their statistical purposes counts as a response), but I'd be really put off by the company. The advertising agency says not one person called to complain.
How do you think you'd respond to an ad like that?
