For the cost of a small printing overrun and a few postage stamps, your customer newsletter can help build your reputation for professionalism with community influentials such as the chief executive and board of directors of the Chamber of Commerce; the mayor or head of the board of selectmen (or council).  Also, consider sending copies to the heads of organizations: the local hospital, the senior center, the library, et al. 

It is a good idea to send a copy or two to the marketing reps of the companies you represent and to any personal and commercial lines underwriters that may be assigned to your account. Again, the objective is building good will by demonstrating the professionalism of your agency.
