Email filtering is a process used to manage incoming emails by automatically sorting them based on specific criteria. This can include identifying spam, categorizing messages by sender, or prioritizing important emails. Email filters help users maintain an organized inbox and reduce the clutter of unwanted messages. Filters can be set up using various parameters, such as keywords, sender addresses, or even attachments. Many email services, like Gmail and Outlook, offer built-in filtering options that allow users to customize their email experience. By using these tools, individuals can focus on the messages that matter most to them.
