Email Spam Filter Software

Email Spam Filter Software Overview

Email spam filter software, also known as email anti-spam software, is used to prevent malicious content from being delivered by email and to prevent sensitive information from being leaked through email. The software uses AI and machine learning to scan emails and attachments for potential threats and then blocks or quarantines the delivery of suspicious messages.

An email’s header, sender and recipient IP addresses, message content, attachments, and links are evaluated for questionable characteristics. Email viruses, malware, malicious links, phishing attacks, spoofing/impersonation, ransomware, and spam are identified.

Organizations and businesses use email filtering software to stop phishing attacks and the inadvertent downloading of malware. The intent of both phishing attacks and malware is to take advantage of an email recipient’s lack of awareness to gain access to proprietary information and resources. This software helps to prevent compromising a company’s confidential data and its IT infrastructure.

Email administrators can whitelist known senders and approved content providers, and blacklist bad actors. Email filtering supports the routing of email into a variety of designated categories and folders for wanted and unwanted emails such as bulk mail and junk mail. Increasingly, artificial neural networks are being used to identify personal preferences when organizing email inboxes.

Email filtering software tools provide encryption and scanning for outgoing emails. Data Loss Prevention (DLP) features prevent the inadvertent or intentional leaking of sensitive data from a business. Account takeover protection prevents hacked accounts from sending out restricted information. This preserves an organization’s reputation and integrity by halting the distribution of questionable content and confidential information.
