Email content filter can tag, filter or block email messages that meet certain guidelines or those sent from specific mailers. With built in developer code and customizable filters, the number of junk email messages that make it to a recipient's inbox can be greatly reduced. Fewer email messages can save people time and allow IT organizations the opportunity to shift resources to more valuable projects.

The Spam Problem

Sending and receiving email messages has transformed the way that companies interact with its employees, customers and competitors. Unfortunately, mass marketers have taken advantage of the technology by sending advertising, services or pornographic material to very large distribution lists. These messages can clog a smaller email server and force companies to troubleshoot junk email instead of work on new projects.

Large internet service providers estimate that as much as 30% of the email received by its customers is unsolicited, or junk, email. It is unlikely that any action will completely cure the problem but using an email content filter can cut down on the number of messages that find their way to an inbox. While junk email will continue to be sent, filtering out spam messages will allow a company or individual to operate more efficiently.

Understanding an Email Content Filter

Each filter will have its own code and rules predetermined to catch spam in different ways. Some filters are based using Bayesian analysis which studies the structure of the email and attaches a probability to the message while others base their filter simply on keywords or frequency of use. While both have their pros and cons, it is important to find a content filter that allows the user to customize or update it in order to block out as many spam messages as possible.
