Subject
Also called: subject or subject line
The subject of an e-mail is a short description of the message chosen by the sender, which is displayed in the recipient's inbox. This way, the recipient gets an impression of the message content even before opening the e-mail message. The subject can also help make it easier to find old messages later.
Choosing a good subject line is crucial in e-mail marketing. A catchy subject determines whether the recipient of a business e-mail will open it or delete it unopened.
