What is tone and why is it important when writing a business letter?

Tone refers to the attitude or emotional quality conveyed in writing, influencing how the message is perceived by the reader. In a business letter, tone is crucial because it sets the relationship between the sender and recipient, reflecting professionalism, respect, and clarity. A well-considered tone can enhance communication, foster goodwill, and effectively convey the intended message, while an inappropriate tone may lead to misunderstandings or damage relationships.
