What does to whom it concerns mean?
To the appropriate recipient for this message, as in I didn't know who was responsible for these complaints so I just addressed it “to whom it may concern.” This phrase is a formula used in letters, testimonials, and the like when one does not know the name of the proper person to address. [
Is it bad to address cover letter to whom it may concern?
Never use “To Whom it May Concern” or “Dear or Sir or Madam”—nothing could be more generic (not to mention archaic). Your cover letter could be the first opportunity you have to make an impression on the hiring manager, so make sure you show that you did your company research.
