How is the subject line written?

English business letters usually contain a subject line. Although this line is not necessary, it is often used for practical reasons as it indicates the letter’s overall intent. Small differences between British and American English need to be considered:

  • In British English, the subject line usually appears between the salutation and the body of the letter. In some cases, it may also be written before the greeting.
  • In American English, the subject is generally printed before the salutation. To announce the matter, ‘Subject’ or ‘Re’ (‘reference’ or ‘regarding’) is frequently written at the beginning of the line.

In terms of formatting, the subject line is either bold, underlined, or capitalised (the first letter of each word).
