Conventional advice is to search for the actual name of the person who will be reviewing or receiving your letter. I disagree with this and think taking that effort is a waste of time and adds extra stress to an already nerve-wracking process. My advice is very simple and will let you spend your time on perfecting your resume and the content of your cover letter.
If the name of specific person is given in a job listing, obviously that is the name you should use. But, if no name is given you should address your note to the hiring manager. Yes, that means saying “Dear Hiring Manager” in the letter’s salutation. This is preferable to the stilted “To Whom it May Concern” or “Dear Sir or Madam.”
There. You just saved hours of searching and worry about how to address your cover letter. You're welcome.
