What is spam filtering?

Spam filtering refers to the process of identifying and blocking unwanted or harmful emails, which is critical for maintaining the integrity and security of email communications. It involves using various algorithms and rules to analyze incoming messages, allowing the system to differentiate between legitimate emails and those that could be spam, phishing attempts, or contain malware. By adeptly filtering out these unwanted emails, spam filtering not only protects users from potential threats but also helps in reducing the clutter in their inboxes, allowing them to focus on important communications. The effectiveness of spam filtering mechanisms directly contributes to a more secure and efficient email experience for users.
