What is an essential element of email etiquette?

Including proper greetings and closings in an email is a fundamental aspect of email etiquette. Proper greetings establish a courteous tone and show respect for the recipient. They set the context for the communication and create a positive atmosphere. For instance, addressing the recipient with their name or title can engage them more personally. Additionally, closings provide a professional finish to the email, reinforcing the sender's intent and offering a polite conclusion. This approach fosters good communication practices, helps build relationships, and maintains professionalism in correspondence, essential for effective workplace interactions.

The other options do not align with effective email etiquette. Using multiple subjects can confuse the message's core intent, while keeping an email lengthy and detailed might overwhelm the recipient, reducing clarity and engagement. Omitting action items can lead to misunderstandings about the expectations and follow-up required, making it crucial to clearly indicate the necessary actions within the email.
