Newsletters  are one of the most cost-effective ways to communicate with customers and employees. Whether they are simple front-and-back laser-printed sheets or more elaborate graphic-intense, four-color eight-page  "mini-magazines" or timely on-line "web-zines," newsletters convey an organization's desire to stay in touch with customers and supporters, and for  that reason alone, they are indispensable public relations and sales vehicles. You  may be surprised to discover how inexpensively a good newsletter can be produced  and delivered.
