Match the paper and font style to your resume.
Create the same heading for both the cover letter and resume.

Address the letter to a specific individual. Call to request the name and title of the person hiring for the position. As a last resort, you may direct the letter to someone with a specific job title such as “Director of Human Resources.”
Sound positive and confident in your letter and write an attention-getting introduction.

Be very clear about the position you are applying for and point out how you are uniquely suited for the job by listing relevant qualities.

Focus on the needs of the employer and how hiring you will lead to higher production and greater efficiency.

Tailor your letter around the question, “how will the employer benefit by hiring you?” Use the position announcement and company literature for clues about what to stress.

Add power by using facts, examples, or evidence.
For example, the statement “can initiate and accomplish tasks with little direction” has no credibility until back-up with an example: “independently began operation of organization’s website.”

Paint an accurate picture of yourself. Don’t exaggerate or lie.

Conclude your letter by informing the employer of your intent to contact him/her within the next few weeks and make the follow-up call once you can assume the resume has been received.

Make sure your letter is PERFECT-no typos, misspellings, or factual errors. Have someone proofread the letter before you send it out.
