A solution that doesn't block good emails
Low False Positive rate
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.
" We have been amazed at how effective ZeroSpam has proven itself to be. (...) We have tested many Anti-spam solutions and yours blew us away. It works, and requires very little time to manage the quarantine. Our clients will be significantly safer and we have you to thank. You have truly impressed us. "
