Include your name and contact information at the top of your cover letter. Try to find out who is responsible for interviewing/hiring someone for the position to which you’re applying and address your letter to that individual. Sometimes this information can be found on a company website or on a business information site like Manta.com. Providing someone’s name will get your cover letter (and resume) further along than the standard: “To Whom It May Concern.” It also shows that you’ve done some research — at least enough to know who’s who at the company.
