Chris Baggott, author of Email Marketing by the Numbers, knows his stuff when it comes to email marketing. In 2001, he set up a desk in his friend's garage and worked alongside Scott Dorsey and Peter McCormick to build ExactTarget, which has since grown to become a world-leading, multi-national email service provider. In 2007, Chris created Compendium, a business blogging platform with the software, tools, and services that enables companies to create, capture, moderate, and broadcast their message online. Two years ago, Invesp dubbed Chris one of the 25 most influential marketers in the world.
