Send E-Mail Bounce-Backs to Get More Sales

Here’s one company that knows the best person to sell shoes to is . . . someone who just bought shoes. Literally.

About two months ago, I bought a pair of Doc Martens on sale at Zappos.com. They’ve got an extremely shopper-friendly website — and good prices too.

Last week, I received this e-mail:

"Just wanted to let you know, we’ve got just one pair of your shoes remaining in stock. After that, we’ll never have these again."

I ordered them that minute.
