Every week I get a marketing email from Quizno's. "More spam, how annoying..." you might say, and typically I'd agree and go straight for the unsubscribe link. However Quizno's is doing something very smart. They're regularly including real, honest to goodness value in their emails. Every week, it's a new coupon. Never an email without one. That's tangible value and it keeps me going there almost once a week when I otherwise wouldn't.

So, the person in front of me in line who isn't getting the emails isn't getting the savings that I'm getting. That makes staying subscribed a no brainer. Isn't that their goal? Saving some dough is definitely my goal.
