Spam Filter Test - How Does it Work?

Is or isn't a message spam? This is how a spam filter test works. Who needs such a test? Web developers that depend on email marketing campaigns are the first interested in knowing whether their newsletters have any chances of passing an over zealous anti-spam program. A web marketing campaign can be thus tested against spam blockage tools. Here are a few tips to check how things work.

The spam features in a newsletter are easy to identify if you have a mailing list software that generates the messages. There are modern programs that have the feature incorporated while others require subscribing to get access to the service. The help documentation of an email blaster should help you identify the spam email filter test application. The testing mechanism could be outdated but even when they don't correspond to the latest trend, they can still provide some form of guidance.

The spam filter test variants include reports on headers as well as spam scoring details. The tests for Outlook and Outlook Express can even be performed online. There are other concerns related to the spam filter tests and these represent the evaluation of anti-spam programs from the perspective of the user. This time we refer to the spam filter test meant to determine how efficient a filter is against spam.

The really good anti-spam tools are those that can distinguish legitimate messages from real spam, and not the programs that block as many emails as possible. A spam filter test should be able to find out how many legitimate emails a anti-spam tool blocks and how many real spam messages pass undetected. Software designers thus aim to train programs to learn how to avoid such mistakes.

The spam filter test requires the use of an email that is unknown to the program. Results would be unrealistically good for the email sender that was used in training, which is why experts divide the messages they use in testing as training and control groups. In case such experiments are successful all the way, then, the Internet may become a spam free zone.
