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.
" With our new Office 365 and Exchange-online practice, we’re recommending to every customer that they add ZEROSPAM. We can sign up many customers, we can get them up and running very quickly and on-going management is almost as simple as sending them the bill. Convincing customers to use a pretrial is actually very easy. Once you get somebody to experience that quality, that’s 90% of the sales cycle right there! "
