Where is text marketing valuable?
It seems that an under-appreciated value of text messaging from a marketing perspective is the ability to provide the consumer with a sticky note. Texting becomes the analog to jotting things down. Too often I see billboards with a long URL that I never remember or I'm in places where doing something else is not going to happen (like being in a theatre) and need a means to capture information.
The use of a short code to retrieve a reminder (phone number, URL, event, location) is an interesting approach.
