Spam detection is the process of identifying unwanted or harmful messages, often sent in bulk, that clutter our email inboxes. These messages, known as spam, can include advertisements, scams, or phishing attempts that aim to trick users into revealing personal information. By using various techniques, spam filters can analyze the content and sender of emails to determine if they are legitimate or not. To effectively filter out spam, many email services employ algorithms that look for specific patterns or keywords commonly found in spam messages. These algorithms continuously learn from user feedback, improving their accuracy over time. This helps ensure that important emails from friends, family, or colleagues are not mistakenly marked as spam.
