Spam Filtering Provided by

It’s estimated that approximately 95% of all email sent is spam. Spam is the most complex problem for email hosting systems and leads to millions of dollars in lost productivity and additional infrastructure costs for businesses. Businesses that try to maintain in-house email servers are fighting a losing battle against spam. Spammers adapt to technology changes and improve their techniques on a daily basis, learning new methods to elude common spam defenses and acquiring more sophisticated computer networks to bombard mail systems and penetrate inboxes.

Solving the Spam Problem for You

In order to win the war against spam, we evolve our spam defenses faster than spammers evolve their tactics. If you choose to outsource to PentaMails, your business email will run on a state-of-the-art email hosting system with numerous levels of anti-spam protection.

Our spam filtering system, powered by Cloudmark®, features Advanced Message Fingerprinting™ and real-time threat intelligence to rapidly detect spam, phishing, and viruses. Instead of analyzing message text, Cloudmark generates electronic fingerprints that precisely identify abuse in all languages and formats. These message fingerprints are stored locally at PentaMails and updated in sub-minute intervals. This automated approach delivers spam filtering accuracy of 98% or higher together with near zero false positives.

We also empower our customers and end-users with control over their personal safelists and blacklists to further keep their inboxes clean. Safelists allow certain senders (email addresses, domains, or mail server IP addresses) to bypass the anti-spam system. Conversely, blacklists allow customers to block mail from certain senders. Customers can also control what to do with spam once it has been identified.
