What is the function of an email filter?

The function of an email filter is to organize and sort incoming email messages. Email filters are tools that help users manage their inboxes by automatically sorting messages based on predefined criteria, such as the sender’s address, specific keywords, or other attributes. This process helps in categorizing emails into folders, marking them as important, or even blocking unwanted messages, which makes it easier for users to find and prioritize the emails they need to address.

For instance, a user might set up a filter to automatically direct all emails from a particular sender into a designated folder, or to flag emails that contain specific terms in the subject line. This functionality enhances productivity by reducing clutter in an inbox and ensuring that important messages are readily accessible.
