When we write "Thanking you" at the end of a letter do we put a comma after it before writing other things like "Yours sincerely" and name because "Yours sincerely" is followed by a comma? I am confused because if I write:
Thanking you, Yours sincerely, Name
does it mean that I am thanking myself because in normal English "Thank you" is followed by the name of the person we want to thank?
Does putting or not putting a comma after "Thanking you" make a difference to the meaning conveyed?
