For every waking moment, more than 4 billion people worldwide are inseparable from their mobile phones. The U.S. mobile market is growing rapidly and by the end of 2008 had over 270M subscribers. Even more interestingly, in 2008, 1 trillion text messages were sent in the United States—exceeding the number of mobile voice calls. Increasingly, a great way to reach your customers is via mobile texting, aka SMS marketing.

We’re not talking spam! When merchants, services, and brands let customers opt in to marketing programs, you’ve got marketing that strengthens customer relationships, builds loyalty, and fosters viral marketing. SMS marketing makes an offer you can’t afford to ignore: Unparalleled reach and timeliness, unparalleled cost-effectiveness, and unparalleled customer response—23% of U.S. mobile phone users remember seeing mobile advertising during a 1-month period, and over 50% responded to the ad, according to a recent Nielsen Mobile Report.
