I'm sorry but they're relatively useless. Focus on delivering a great product. Interact w/ your customers through gaining feedback and providing support. Deliver messages to your customers through a single channel. Spread the word about your product by participating in communities that could take advantage of your product. So for example if you're an auto parts maker. Heavily participate in local racing leagues and drag clubs. Setup shop on the weekends at local auto parts retailers offering free install lessons. Create a an opt-in mailing list, only email customers when you truly have something new and valuable to offer them. Actively seek out customer feedback through the events mentioned above. Likewise support channels should serve to notify customers of additional products in your lineup that could benefit them. None of these methods require a separate marketing person. The only requirement is someone who is knowledgeable about your product lineup and community and is a good people person w/ decent writing skills. My 2 cents, thanks :)
