While the resume offers a summary of your education, experience, and skills, a cover letter is an opportunity to tailor your application to each opportunity.
Effective cover letters are constructed with close attention to purpose, audience, content, and format. Along with your resume, a cover letter provides information a prospective employer will use to decide whether you will reach the next phase in the application process: the interview.
A cover letter provides, in a very real sense, an opportunity to let your prospective employer hear your voice. It reflects your personality, your attention to detail, your communication skills, your enthusiasm, your intellect, and your specific interest in the company to which you are sending the letter.
Therefore, cover letters should be tailored to each company you are applying to. You should conduct enough research to know the interests, needs, values, and goals of each company, and your letters should reflect that knowledge.
A cover letter should be addressed to the specific company and the specific individual who will process your application. You can usually find this through research or simply by calling the company to find out who you should address your letter to.

Pick out the most relevant qualifications listed in your résumé and discuss them in detail, demonstrating how your background and experience qualify you for the job. Be as specific as possible, and refer the reader to your résumé for additional details.
The concluding paragraph of your letter should request an interview (or some other response, as appropriate). State where and when you can be reached, and express your willingness to come to an interview or supply further information.
Close by thanking your reader for his or her time and consideration.
