An often overlooked albeit critical aspect in generating increased sales is a focus on customer retention. Marketers all too often focus too greatly on customer acquisition and forget that on average 80% of a firms revenue is derived from 20% of their customers. Providing E-Newsletters to your most valued and profitable customers is extremely advantageous as it ensures that these customers are notified of all current and upcoming promotions. In addition, special coupons and shopping incentives not only condition valued customers to look forward to receiving newsletters, but prompt additional purchases. Hyperlinks to your website or online articles provide readers with easy access to additional information or immediate purchases. Newsletters also provide a great opportunity for brand promotion as they are delivered directly to your target market.
