If I am writing a job application cover letter and am not able to find out who exactly is going to read my e-mail, is it appropriate to use "Dear Sir or Madam"? Also, I'll be sending my CV and cover letter as attachments: do I also start the actual e-mail with "Dear Sir or Madam" and end it with "Yours sincerely"? What is the proper etiquette? Do you have any other suggestions regarding sending my CV and cover letter? Thanks in advance! I'd appreciate any tips at all!
