I’ve been subscribed to the Cool News of the Day newsletter (also available in convenient blog form) for several years. It’s the ONLY email newsletter that I read daily.
Cool News highlights innovation in marketing strategy and execution. A lot of the articles skew towards retail, but they is always some gem of information in each of the articles.
As an aside, I’m pretty sure that Tim Manners, the editor, is going to join us on the Advisory Board for the Marketing & Online Communities conference.
