Low false positives rate email spam checker

Accurately blocking spam and dangerous messages is not an easy thing to do, but that alone does not define a great email filtering job. Making sure that legitimate messages are delivered is also key.

The margin of error is very low on both sides of this fine line but a few blocked legitimate messages (called False Positives or FPs) can have a great impact on daily operations.

The ZEROSPAM solution has a very low proven FP rate. This has been proven test after test by a reputed and neutral third party (Virus Bulletin) since March 2012. On 6 different occasions so far, ZEROSPAM has earned the VBSpam+ award which requires no false positives during a single test. Typically, in the first few weeks of service, new customers will release a few legitimate messages from the quarantine, make corresponding entries in the sender’s whitelist and then stop monitoring the quarantine altogether.
