How do you end a letter is it yours faithfully or yours sincerely
Dear Sir or Madam,
Dear Mr X,
If you use a name, end with 'sincerely'. If you do not use a name, use 'faithfully'.
If you're writing to someone in the US say "Sincerely yours." "Faithfully yours" sounds archaic to these yankee ears.
In Britsh English, we don't often use 'Sincerely yours', and I don't think I've ever seen 'Faithfully yours'.
