The sales letter format should emphasize key points while maintaining simplicity. Do not repel the customers or clients. Have normal spacing between lines and the contents just right so that the reader does not feel over_burdened reading your letter. Get the reader to feel as if he is invaluable to you and your company. The pronoun "you" in place of "we" instills a sense of warmth in the reader, drawing them closer to your business.
Cover Letter Format Tips: 1. Make sure what you write is clean and easy to read. Don't make your prospective employer's job more difficult by providing them with a cluttered mess. 2. Ensure that you have no spelling or grammatical errors. This is essential; these will stick out like a sore thumb and will show your prospective employer that you didn't put much effort into applying for the job at hand. 3. You might want to consider starting off with a high quality motivation letter template. You can start with a professional format and then fill in the details specific to you and job you're applying for.
