You're looking to get your letter to the person who can give you a job. It also makes it obvious who you're trying to reach.
It isn't gender-specific, which eliminates that issue, and it also doesn't sound awkward. The majority of people use 'Dear Hiring Manager.' This is a good salutation for a couple of reasons. There are several acceptable greetings you can use. What if you don't know the person's name though? How should you address your letter and ensure that it is polite and gets to the right person? The name 'Terry' could refer easily to a man or a woman, for example. Indeed, it's better to leave out titles in your cover letter salutations since you don't want to make assumptions about gender. You don't need to add in a relevant title if that's the case. If that's the case, you should always address your cover letter to that individual by full name, first and last.
When you're applying for a job, the best-case scenario is that you know who is supposed to receive and review your application. Greet your future employer the proper way with these cover letter do's and don'ts.
