Dan Faggella sent me an email last month that essentially said, "Hey Nick, I'm a fan of the show. I have some expertise in email marketing, and I know many of your listeners are working to build their online presence and their email lists. Would it make sense to do an episode on some list building and email best practices?" And then he added the kicker: "I'm making $50k/mo selling martial arts training videos right now, and I have other businesses as well..." OK, I'm listening!
