What is the purpose of having color categories in email management?

Using color categories in email management serves the primary function of helping users easily identify and group associated items. This visual categorization allows for quicker recognition of emails that relate to a particular project, topic, or type of task, thereby improving organization and efficiency in managing the inbox. For example, an administrator may use different colors to represent different departments or priority levels, making it easier to locate emails at a glance.

While prioritizing emails based on sender, filtering spam emails, or deleting unwanted emails quickly are all valid email management strategies, they do not leverage the specific visual categorization that color coding provides. Thus, the use of color categories is particularly effective for organizing and making sense of related emails simultaneously, enhancing overall workflow.
