Do you need to write a business letter? Not sure about the best layout to use or what to include in your letter? It's important that all the business letters you write are properly formatted and professional in appearance. When you are writing to prospective employers, colleagues, professional and business connections, the layout of your letter is almost as important as what you are writing. If the letter isn't formatted correctly, doesn't have enough space between paragraphs, and uses a non_traditional font style or size, it can reflect poorly on you.
In most cases, the business letter will be the first impression that you make on someone. Though business writing has become less formal over time, you should still take great care that your letter’s content is clear and that you have proofread it carefully.
