How to write footnotes in a letter
A footnote is a brief passage of text placed at the bottom of the page that contains the author's comment on the main document or bibliographic references. Footnotes are usually marked by an exponent ¹ to indicate the location in the text where the reader is referenced.

If you are writing a business letter where you refer to other documents or want to add a parenthesis to your personal correspondence, the footnotes in writing are very easy.
