Newsletter is one of the most frequently distributed publications and caters to one topic at a time. Most common forms of newsletters are newspapers and leaflets, and are usually issued out to subscribers instead of masses (as is in the case of pamphlets). The main purpose a newsletter serves is dissemination of information about one specific matter that the subscriber is interested in. usually it contains news and upcoming events of the organization publishing them, along with their business and contact information. Some newsletters are sold out as well-as in the case of school and college newsletters-and some are distributed free of cost as a marketing tool.
