To save your reader time and to call attention to your strengths as a candidate, state your objective directly at the beginning of the letter. Example: I am seeking a position as a manager in your Data Center. In such a management position, I can use my master’s degree in information systems and my experience as a programmer/analyst to address business challenges in data processing. If you have been referred to a company by one of its employees, a career counselor, a professor, or someone else, mention that before stating your job objective.
However, before using a general salutation (or leaving off a salutation), try to find out the name of the person you are contacting. If you are applying or inquiring about a job and the hiring manager’s name is not included on the job listing, you might look up the title of the employer or hiring manager on the company website. If there is a contact number, you might also call and ask an administrative assistant for the name of the hiring manager. If you are sending a different type of letter, you can still look up the person’s name on the company website, or speak to an administrative assistant or contact at the company for the name of the person you are trying to reach.
