Up front, text messaging is like e-mail—boring, yet incredibly effective. Even though there are numerous options for mobile communication, the good old text message is still a surefire way to reach the masses. According to Clickatell, 9 out of 10 Americans can receive text messages, when, for instance, Twitter reaches only about a quarter of the population. And, in 2010, around 6.1 trillion text messages were sent globally. The astonishing number (that’s thousands of billions) also represents steady growth, as it is triple the amount of text messages that were sent in 2007.
