What is the primary function of filters in Gmail?

The primary function of filters in Gmail is to manage the flow of incoming messages. Filters allow users to set specific criteria so that incoming emails can be automatically sorted, labeled, marked as read, or even forwarded without manual intervention. This automation enhances productivity by ensuring that important messages are prioritized and that unwanted emails are handled according to the user's preferences.

While filters can indeed lead to the deletion of unwanted emails, organizing emails into folders, and even selecting priority messages, their core purpose is centered on managing how incoming messages are processed and organized within the user's inbox. This capability helps users maintain a well-structured and efficient email environment, making it easier to focus on important communications.
