Final answer:
When writing a letter to a sophisticated client, use industry-specific jargon and assume they have a certain level of knowledge, while with an unsophisticated client, language should be simple and concepts clearly explained. Both letters should maintain a formal and polite tone, be clear, concise, and direct.
Step-by-step explanation:
The difference between writing a letter to a sophisticated client versus an unsophisticated client lies in the language and the complexity of the concepts discussed. For a sophisticated client, you may use industry-specific jargon and assume a certain level of knowledge about the topic. The tone remains formal but can incorporate more advanced concepts and professional terminology. On the other hand, when writing to an unsophisticated client, it is crucial to avoid jargon and explain concepts in a straightforward, accessible manner. Ensuring clarity and ease of understanding is primary, which might require the use of simpler language and additional explanations.
Business writing, regardless of the audience, should always be clear, concise, and direct. The body of a business letter typically begins with an introduction to the purpose of the letter. Relevant facts and details to support this purpose are then provided in the subsequent paragraphs, and the closing paragraph should reiterate the importance of the letter's purpose. Formality is key in business communication, so avoid using text language and casual expressions. Politeness and respect should be maintained throughout the letter, ensuring that the tone is appropriate for a professional setting.
