Email Remains a Top Mobile Activity

While just over a quarter (28 percent) of non-smartphone users said they check their email "constantly" throughout the day, nearly half (45 percent) of smartphone users do so, according to ExactTarget.

In fact, checking email is a more common mobile web activity than visiting Facebook (23 percent) or Twitter (five percent) among smartphone users.

Overall, the home PC remains the top location from which consumers constantly check email (24 percent) with 63 percent using it to check email daily. Meanwhile, 16 percent of email users overall constantly check email from a work or school computer (22 percent daily).

Eleven percent of email users check constantly from a mobile phone (15 percent daily) but the numbers are minimal for iPad/tablet users with two percent constantly checking and three percent checking daily.

Even App Store "Marketing" Apps Must be Marketed

Despite the hype about mobile apps, it remains difficult to "monetize" them, for several reasons. Most apps sell for low prices, so a developer needs huge volume. But volume means getting noticed, and simply creating an app and listing in on an app store does not guarantee attention.

That increasingly means a successful app not only has to provide value, but has to be promoted. And that means all the traditional thinking about traditional marketing still holds. Developers have to take affirmative steps to promote their apps; they won't sell themselves.

"The App Store is not a marketing vehicle; it is a distribution vehicle," said Raven Zachary, president of digital creative firm Small Society.

Of course, not all apps are sold. Some are themselves marketing vehicles. But an iPhone app can cost $50,000 or more for an agency to develop. So even the marketing vehicle must be marketed.
