I just had to share this one for everyone. Cambridge University did a marketing study a few years back. It went like this: 10,000 flyers were sent out to a specific mailing list and the response rate was 1-2%. 10,000 of the same flyers were sent to the same people 3 months later with a big red dot on it. This generated 3-4% return calls. As you can see, it is ALL about what is on the flyer itself.
