Something lumpy in your direct mail
When you receive an envelope in the mail that is lumpy, it makes you want to open it. You cannot help yourself. We did a direct mail campaign with a goldfish with a clothes pin on his nose. A real, 3 dimensional clothes pin (small). The message was: Does your marketing stink? We gained several new clients. They actually saved the direct mail piece and brought it in with them for the appointment. I was reminded of this when I ran across this story online: http://bit.ly/1SUGdF
