Email subject abbreviations

Email subject abbreviations are letters or numbers that are used to help a reader quickly understand the contents of an email without having to read it. These abbreviations can tell a reader what the email is about. Some common abbreviations are FYI (For Your Information), ASAP (As Soon As Possible), and RE (Regarding). When combined with other words, they can create phrases such as "RE: Your Order" (Regarding Your Order).
