What is the main purpose of an inclusive email indicator?

The main purpose of an inclusive email indicator is to identify emails that contain the most complete prior content. This feature allows users to easily recognize emails that may include previous messages or context necessary for understanding the current discussion. By marking these emails, users can quickly access and review comprehensive information, making it easier to engage in conversations without needing to sift through multiple emails to find the relevant content. This functionality is particularly useful in busy environments where clarity and context are vital for effective communication.

The other options do not accurately reflect the purpose of the inclusive email indicator, which focuses specifically on providing context through the inclusion of email content.
