As mentioned previously, application letters and cover letters are not the same. A cover letter identifies an item being sent, the person to whom it is being sent, and the reason for its being sent. A cover letter provides a permanent record of the transmittal for both the writer and the reader.
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.
