This card that came in a recent book purchase made me smile. The book publishers thanked me for my purchase, told me what types of books they tended to sell, and asked me whether I wanted to receive updates on other books of theirs as they came out. In one simple card, I had a warm thank-you, some information, and a call to action.

That card makes me think long and hard about just how clean and simple good marketing can be. How about you?
