What is the main purpose of writing a greeting in an email?

Correct answer: To show respect and politeness to the recipient

An email greeting establishes a courteous tone at the beginning of the message and acknowledges the person receiving it. Forms such as “Dear Ma’am” or “Hello” should suit the relationship and level of formality. A greeting is not meant to hide the subject, remove the email, or add pointless length. It is a basic part of respectful email etiquette, so option B is correct.
