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.
You do not have to worry much about being a copycat if you do not find the most unique cover letter format in town. Just be sure that the contents of the letter have a clear and definite direction. This will bring about a good flow in the contents of the letter.
