Broadcast letters are, by definition, distributed to many employers. Thus, they are less focused. Format may appear similar to other letters, and it is most important to have the company name appear prominently early. While less company-specific information is contained, you must still show readers that you know the organization's name and the nature of their business. Be aware that quantity of letters is not as crucial as the quality of content. Broadcast letters can be good first efforts and momentum builders, if you maintain appropriate expectations and follow up effectively.
