When creating a business letter, you should follow these guidelines:
- Write clearly and concisely.
- Remain polite even when dealing with a dispute.
- Eliminate mistakes.
The following guidelines should be avoided:
- Use a font, size, and style that is fancy. (It's better to use a professional and easy-to-read font.)
- Use informal language like you would if you were writing a close friend. (Business letters require a formal tone.)
