Numo's SMS preview application has achieved 600,000 new registrations in the last two months. The application displays a preview of SMS messages of any inbound text messages.

The app is targeting Android and Symbian mobile devices, it is free and remains one of the most popular download at app stores. The app is available for download from Numo's website.

For those who are using SMS as a marketing tool this is not bad news - I promise! The previews, lets call them snippets, are just like a search engine result. The opening to your SMS message can give it context and appeal. So design you messages with this in mind, experiment with this application - for instance do attached images appear in the preview?

Developments and obstructions to existing strategies can be turned to your advantage and don't forget the iPhone allows SMS preview by default anyway, so make the first 8 words an encouragement to open the entire message.
