Hello, I found a similar topic, however it did not fully answer my question, so instead of digging in the old one, I decided to start this new one. I am writing a letter. I know that it is directed to a man, but I dont know his name or who he exactly is. In this case, is it correct to say "dear sir" at the beginning? I know that the "Dear sir or madam" is the most common one, but it is pretty much awkward to use it when I am sure that im writing to male person. Could someone give me any advise in this case please?
