Because spammers' tactics are constantly changing, the anti-spam technology that used to work before will no longer be as effective today. A good anti-spam technology worth its salt has to work harder just to keep pace with the spammers.

Bigfoot Anti-spam has raised the level of its game by reinventing the way spam is classified and filtered using a highly sophisticated multi-level approach.

1. Identity Specification Metrics
The origin of the email is checked in our proprietary whitelists and blacklists.

2. Content Characteristic Analysis
Email is validated against a set of predetermined spam signatures.

3. Statistical Inference Algorithm
Email content is scanned for spam indicators using automated statistical techniques.

We have further raised the barrier for spammers by equipping the Bigfoot Anti-spam with the capability to "learn" about new strains of spam and "train" itself to recognize them.

With Bigfoot Anti-spam, no spammer is smart enough!
