California salad-bar chain Mixt Greens has used email and mobile to help drive traffic at local stores and increase revenue. The restaurant chain teamed up with mobile loyalty firm Thanx to
encourage restaurant visitors to sign up for their loyalty program while in the store. From there, customers are invited to opt-in to the chain's email newsletter where they are sent targeted offers
based on their location and past behavior. Customers can also add a credit card to the mobile platform to make it easier to pay in-store. Within three months of launching the program, Mixt
Greens signed up about 3,000 customers sign up, a 10 percent increase in its database.
