In a letter or note stating 'sincerely' at the end, there is a comma after 'sincerely'
The word "sincerely" or the word pair "sincerely yours" is used in the closing, which comes immediately before the signature on a letter.
In "Sincerely yours," you should capitalize only the first letter of each word (Sincerely Yours).
Sincerely, as a closing to a letter (or Sincerely yours).
