If you're marketing to consumers, you may think your messages are being viewed at home on the family computer. But your customer may be sneaking a peek at Facebook on an iPhone during work hours - and then checking personal messages on Gmail. Prospects may be tweeting in front of the TV - and checking your website after seeing your commercial.
If you're a business-to-business marketer, you may imagine that your website or email message will be viewed on your prospect's 21-inch (or perhaps much larger) work monitor. But maybe that prospect is sitting in the airport with a much smaller notebook computer and is squinting at the 9-point type that looked just fine while projected on your conference room screen. Worse yet, she may be scrolling through emails on her BlackBerry during a particularly boring meeting - and your photos don't show up. Maybe your headlines have disappeared off the edge of the screen.
Remember, mobile marketing is not about a platform or list of devices; it's the way people are consuming your messages. Mobile does everything your laptop and desktop can do - and more - including SMS, MMS, email, voice, Internet, the mobile web, Bluetooth and apps.
