I'm thinking about making a direct mail campaign with promotional items (such as pens, flash lights .. ). So I would like to know if somebody have done it and what kind of promotional items did he/she used. Did you engrave the items? Which company did you use to purchase your promotional items? Did you mention something about the item in your letter?
I know Gery Halbert used quite effectively promotional items in combination with his letters. Something like:
"Do you know why I attached this one dollar bill? Well there is a reason. I know it will grab your attention"
I would appreciate if you share similar experience with direct mail campaigns.
