Mainstream spam control providers generate false positives — and they either delete them or sent them to a junk folder with all the spam. If you try to find those needles in the haystack, you are more likely to simply delete them along with the spam.
If you lose email, it could be new business you lose along with it.
MERCMAIL does things differently. First, we reject more spam transactions before they send the message, than competitors catch in total. What becomes false positives for our competitors are put in front of you to be dealt with immediately — no lost emails and no lost business.
