Tom Lindmeier’s Blog @ MarketPlanB

I track the emails of dozens of retail marketers to get a grasp of new developments and take note great ideas. The result is that my in box is flooded with emails on a daily basis.

But there is a better method to track the competition.  The Retail Email Blog has a “search by retailer” function on the left navigation that allows you view the emails of most major retailers.
