Tips to write a concise letter include avoiding overly long sentences and paragraphs, using strong, declarative sentences, and not putting too much information inside one paragraph. Additionally, stick to the relevant information, and change paragraphs when starting a new idea. A persuasive letter should have a crystal clear goal. According to Studyzone.org, a persuasive letter has six basic parts: heading, inside address, salutation, body, closing and signature. The body is the main part of the letter.
A persuasive letter is a letter written to complain about a problem or situation and to offer a suggestion on how to solve the problem. EnchantingMarketing.com suggests the key to write a good persuasive letter is to ensure the goal is clear, to figure out why the readers should care about taking action and what is stopping them from doing so, as well as to cut off redundant words so the persuasive letter is as brief and easy-to-read as possible.
A good persuasive letter should have its main point stated in the first paragraph, ideally in the first two sentences, followed by a brief explanation. The first paragraph should only have two to four sentences. The second paragraph is where the importance of the request is emphasized. This paragraph should be factual, to fully explain the situation of the writer, and explain why it is important enough to warrant action. Use the next few paragraphs to support the request by providing background information and details. Use the last optional paragraph to address the opposite side. State predictions about likely counterarguments, objections, or questions the readers might have. Judgmental statements should be avoided in this section.
