Subject A SUBJECT TITLE at the beginning of a letter, directly after the salutation, provides a further reference, saves introducing the subject in the first paragraph, immediately draws attention to the topic of the letter, and allows the writer to refer to it throughout. It is not necessary to begin the subject title with Re. (with regard to), e.g. Re Application for the post of web designer. When sending email messages this may even be confusing as RE is short for reply s see page 48 Copies
