Here is a topic troubling email marketers, template designers, and business owners since its pitiful release. Outlook 2007 is beyond frustrating for all of us, why? If you’re asking why, allow me to introduce you to the most unpredictable aspect of email marketing:
Email Rending Problems.
Outlook 2007 has essentially gone back in time to the year 2000, crippled with multiple email rendering issues and stripped of its credibility among email marketing professionals.

When an upgrade is released for a software program, it is supposed to be a step up from the previous version…hence the word “upgrade”,…Right?! Many people claim Outlook 2007 is anything but an upgrade. Apart from it’s painstakingly slow loading time, and bulky user interface, Outlook ’07 is destroying beautiful HTML emails worldwide! As a direct result, Outlook 2007 is rapidly driving up email template prices. I wouldn’t blame the template price increase on sheer frustration, but rather on of the extra time it takes an email designer/developer to get their email to render properly in Microsoft’s Outlook 2007
As an email marketer/template designer you need to be constantly ‘digging’ for email compatibility issues and solutions.
