How do you address an unknown person in a resume?
To address a cover letter without a name, use some variation of, "Dear Software Team Hiring Manager." You can also use, "Dear Hiring Manager" if the addressee really is unknown. Remember that "To Whom It May Concern" is an old-fashioned salutation for cover letters.
How do you end a resume cover letter?
Cover letter endings are pretty simple: Just thank the hiring manager. Then add a "Best regards" or "Sincerely" synonym. Finally, leave a space, and add your name, like in this sample sign-off.
Is it OK to say to whom it may concern on a cover letter?
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.
