Email filtering and categorization refer to the processes used to automatically sort incoming email messages into distinct folders or categories based on their content, source, and other criteria. Email filtering primarily focuses on separating unwanted or potentially harmful emails, such as spam, phishing attempts, or malware-infected messages, from legitimate correspondence. This ensures that users receive only safe and relevant emails in their primary inbox, enhancing security and efficiency.
Categorization goes a step further by organizing emails into predefined categories such as work, personal, social media notifications, and promotions. This organization aids users in prioritizing their email handling and improves overall productivity. Both technologies employ a combination of algorithms, rules-based systems, and increasingly, machine learning models, to analyze the content and metadata of emails.

Email filtering identifies and isolates spam emails, including those that pose security risks such as phishing attacks, which account for nearly 96% of phishing incidents. Through automatically detecting and quarantining these emails, filtering reduces the likelihood of security breaches and the potential financial losses associated with Business Email Compromise (BEC) attacks, which the FBI reports to stand at a total of over $50 billion.
Categorization aids in organizing emails into manageable sections, allowing users to prioritize their responses and focus on emails first. This organization is particularly valuable because 83% of organizations reported successful email-based phishing attacks, indicating a high volume of malicious emails that need to be sifted through.
With countries like the USA, China, and Russia leading in spam email generation, the sheer volume of spam emails is overwhelming. By filtering out these unwanted messages and categorizing the rest, individuals and organizations can manage their inboxes more efficiently, ensuring specific messages are not lost among spam.
Filtering helps safeguard sensitive information by preventing phishing emails and malware from reaching the inbox. This reduces the potential for malware infecting healthcare organizations' IT systems and gathering sensitive patient health data. Given that 39% of individuals have encountered suspicious email attachments, the need for email filtering in protecting personal and organizational data cannot be overstated.
