For ease of understanding, let’s compare the filtering process to how you manually classify your emails into personal, work, or subscription folders. _The email filter app will start working as soon as the server receives an email_. It will apply [anti-spam](/content/email-filtering-service/anti-spam) techniques and filter out spam and viruses. It will also evaluate the sender’s email address, subject, and message content and, based on these, it will send the emails to their respective folders. Alternatively, with a non-configured email address, the program categorizes the emails into two categories only – inbox and junk. So, there we have the primary uses of [email filtering – security](/content/email-filtering-service/email-filtering-security) and **anti-spam measures**, and automatic organization of emails. Another usage of [email filtering tools](/content/email-filtering-service/email-filtering-tools), in addition to [inbound email filtering](/content/email-filtering-service/inbound-email-filtering), is checking outgoing emails to ensure employee compliance with company policies and regulations. ![email filtering service](https://media.mailhop.org/duocircle/images/2019/02/email-phishing-protection.png) ### Some Of The Best Email Filter Apps Available 1.
