I’ve written a fair amount about delivering engaging emails - and just provided a great example of how not to… ironically as demonstrated by Apple.

AdMob is among the best at delivering valuable, insightful emails about the industry and their platform. Each month, AdMob sends a “Mobile Metrics Report” which really distinguishes them as leaders in the mobile space – both as thinkers and ad providers. The September report is available online and there are some fascinating nuggets. I encourage you to read the full report as it is clear that the mobile advertising space is growing remarkably fast – and it is being powered by smarter phones, bigger screens and better bandwidth. These trends will continue:

* The number of monthly ad requests in the AdMob network tripled over the past 12 months from 1.6 billion in September 2007 to 5.1 billion in September 2008. This growth is widely distributed with 34 countries sending more than 10 million requests in September 2008, compared to only 16 countries in September 2007.

* In the US, 16 of the current Top 20 devices are new from September 2007. These new devices, such as the Samsung Instinct and Apple iPhone, deliver an improved mobile web browsing experience including larger screen sizes, faster network connections, and other enhanced capabilities. However, the Motorola RAZR and KRZR are still the top two handsets in the United States today.

* Worldwide, the Apple iPhone is now the number 4 handset after the Motorola RAZR, Nokia N70, and Motorola KRZR. There were 103 million requests from iPhones worldwide in September 2008.
