Hi everyone, could you please explain me how is it better to start an e-mail to the person whose gender you are not sure about. For Instance, it's not clear from the e-mail address who it is: a man or a woman. I found such expressions as Dear Sir/Dear Sirs/ Dear Sir or Madam. But it's said there, that such expressions are good if writing to the whole company or department. What if you need to address a single person? Thanks a lot.
