One of the best way to market your product, is to keep your website simple and clear. Campaign Monitor has done just that. Their website looks fresh and clean, and certainly not cluttered. A big screenshot of the product shows you in a split-second what it looks like. Two big buttons for the main actions, and a clear navigation bar at the top. Simple and effective.

Campaign Monitor does what it says, it monitors your campaign. You can setup your own e-mail marketing there, and re-brand it as your own. Perfect for website creators who are looking for good marketing strategies.
