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.
Employers do not have a day to browse all cover letters, which is why people have to brief in the message they want for employers to know. Likewise, they need to be consistent and true to the details and information they will allot in the cover letter. To have the most accurate letter format, they should take enough time to plan its overall construction. They have to know that it can help them land the job they need. Taking shortcuts in some of the information they wish to convey will do them no good. It is strongly suggested to gather up their senses in creating the best cover letter.
