Dear Sir
Dear Mr.John
Dear Mr. John Sir
Dear Sir Mr.John

or any other better pronounse to start

Which is the most polite way to write

Answer 1

If his name is John Brown, you'd address it to Dear Mr Brown. If you want to be more formal, you'd use Dear Sir. Never to Dear Mr John

Answer 2

expensive Sirs, or expensive Sir/Madam, are the two completely suitable. i'd tend to apply expensive Sirs, if writing to a business enterprise quite often, and intense priced Sir/Madam, if i grew to become into writing to a particular activity identify interior of that business enterprise...(e.g. the handling Director). the two way the letter would desire to end "Yours faithfully" in case you comprehend the call of the guy e.g. expensive Mr Smith, or expensive Mrs Jones, then the letter would desire to end with "Yours basically"

Answer 3

how about Dear and their name, or Dear Ms ( the word revolution was to use ms toreplace - mr., miss, or mrs.), that'll get their attention!
