The most simple and straightforward cover letting greeting is to write ‘Dear’ followed by their full name. Also, make sure to use their title such as ‘Dr.’ or ‘Professor’ followed by their full last name if they have them. You can still make the cover letter salutation specific if you don’t know their name. Do some research on the company website to find out which titles they use. You can also address it to the department such as ‘Human Resources’ to make sure it goes to the right place.
