If you want results for your efforts, then what you really need is to understand the most critical aspects of the cover letter. The format is just one aspect. There are more details that you have to take into account. The content is the most essential point you have to bank upon. You might have a very crisp paper with nice format in it but it will not be helpful if you do not indicate the skills and credentials required for a certain job position. Of course, you need to possess the same essential skills, traits and knowledge. Thus, you must evaluate first your qualifications before aiming for the brightest cover letter format.
By following proper sales letter format, you can increase the number of people who will read and respond to your letter. The subject line must be motivating and the envelopes are to be very attention_grabbing. If you are mailing the letter, you can even use colorful envelopes printed with your logo. A famous one_liner or a logo that is not easily erased from memory creates magic for your products and services. Sales letter writing is more effective when properly formatted.
