Capitalizing Complimentary Closes

Guess which is the error:

Best Regards,


Best regards,

Graphic explaining that in a complementary close, only the first word is capitalized. For example, "Best Regards," is incorrect and "Best regards," is correct.

The rule is to capitalize only the first word of a complimentary close. This rule applies wherever you use a complimentary close: emails, letters, notes, and even texts.

These are all correct:

  • Best regards,
  • Best wishes,
  • Warm wishes,
  • Kind regards,
  • With deep sympathy,
  • Sincerely yours,
  • My best,
  • All best,
  • With thanks,

The complimentary close isn’t a title or a heading, so there’s no need to capitalize all the nouns or important words–just the first word, whatever it is.

Note: Sometimes people refer to the complimentary close as the salutation. Don’t let them fool you. The salutation is the greeting.
