An indicator within an email system marks a message for specific attention. This function serves as a visual cue, signaling to the user that the item requires follow-up action, such as a response, review, or completion of a task. For example, a user may set a reminder on a communication requiring a purchase order, ensuring it is not overlooked amidst other correspondence.
This feature offers enhanced organization and prioritization within email workflows. Its implementation reduces the likelihood of neglecting important messages and supports effective time management. Historically, email systems incorporated this functionality to address the growing volume of digital communications and the need for efficient message tracking.
