Use the data you collect from customers to help customers

I was poking around a clothing company site this morning, checking out a few cool looking items, but I didn’t buy anything. Soon after, I received an email “Exclusive 10% off for you” with an image of one of the products I looked at and a coupon to get that item at a special discount. Retargeting once felt creepy, but now we’re used to the companies we do business with knowing a ton about us and using that information to market to us.
