There's an important story over at Mobile Marketer about a recent InsightExpress report:

Digital marketing research firm InsightExpress found that mobile ad campaign norms were four-and-a-half to five times more effective than online norms.

...

“Far from being a one-trick pony, mobile is effective in rich environments like mobile video, minimal environments like SMS and the area in between covered by mobile display,” she said. “Add to this the findings that all verticals are seeing mobile impacts greater than online campaigns and the arguments for not adding mobile to a media plan fall away.”

Some more details about Text Message Marketing in particular:

SMS is also effective at increasing upper level purchase funnel metrics such as awareness measures.

SMS campaigns generated increases of 5 percentage points for unaided awareness, 10 percentage points for aided awareness and 18 percentage points for ad awareness.

Mobile video is still emerging, but shows campaign impact on par with SMS across most key brand metrics.

This channel drove especially strong results against brand favorability.

With an increase of 13 percentage points, compared to 12 percentage points for Mobile Internet and 7 percentage points for SMS, mobile video is demonstrating promise as a way to move the important brand favorability measure.
