In today’s mobile world, the smartphone has become a modern-day equivalent of the Swiss Army knife. People rely on it for web browsing, email, text messaging, social networking, entertainment, navigation, and so much more. In fact, a recent survey by ExactTarget reveals that 78% of US consumers use their smartphone for texting at least once per day, 66% check email at least once per day, and 50% check Facebook at least once per day.

And here’s a really important statistic for marketers: 16% of consumers say they’ve completed a purchase as a direct result of a message received on their smartphone. That’s not just text messages—other messaging channels like email, Facebook, and Twitter are also effective at driving purchases.
