Sure, this direct mail piece probably cost a lot of money to make, but can you imagine receiving one of these postcards with a picture of a Porsche in YOUR driveway? Albeit slightly stalkerish, this clever campaign for Toronto’s Pfaff Automotive entailed parking one of their Posche’s in affluent peoples’ homes and taking a photograph. Each home received a postcard with this image and a headline reading, "It’s closer than you think." Pretty savvy, if you ask us. A 32% response rate indicated an immensely successful campaign. For comparison, an average successful direct mail response rate is 3-4%. While the campaign was definitely pricey compared to normal direct mail, it appears that it was worth it and more.
