The company’s secure, user-friendly Web site also enables its clients to compile profiles of customers in their loyalty programs and conduct highly personalized marketing campaigns via e-mail and text message.

E-mail marketing can give businesses a substantial return on investment if done right, providing returns of $51 for every $1 invested, as opposed to an average $12 for every $1 invested in traditional direct marketing campaigns, according to a recent study by the Direct Marketing Association of America.
