E06: Composing subject of email

QUESTION: How do I decide what to put in the “subject” area of an e-mail?

ANSWER: Subjects should be short and reflect the content of the e-mail. The subject appears for the recipient to prioritize the opening of their e-mail. If your message is very important you might put “Urgent” in the subject. If it is just about dinner plans you might type in “Dinner.”
