A newsletter is a regularly distributed publication generally about one main topic that is of interest to its subscribers. Newspapers and leaflets are types of newsletters. Additionally, newsletters delivered electronically via email (e-Newsletters) have gained rapid acceptance for the same reasons email in general has gained popularity over printed correspondence. Newsletters are given out at schools, to inform parents about things that happen in that school. Sending newsletters to customers and prospects is a common marketing strategy, which can have benefits and drawbacks. General attributes of newsletters include news and upcoming events of the related organization, as well as contact information for general inquiries.
