Squidoo: Using newsletters to market your business. by Roger Parker
Consistency is the key to newsletter success. The best way to achieve consistency is to the number of pages in each newsletter. A single-page, two-sided newsletter that appears every month is preferable to a four-page newsletter that appears every other month or an eight-page newsletter that appears quarterly. Your goal is to build awareness and maintain mindshare among clients and prospects. The shorter your newsletter, the more frequently you can mail it and the greater the number of prospects you can send it to.
