The Zipline email hosting environment offers a built-in spam filter solution. This service is done through Apache SpamAssassin. Apache SpamAssassin is the #1 Open Source anti-spam platform and it is used widely across the Internet to combat spam and bulk email. SpamAssassin uses a robust scoring framework and plug-ins to integrate a wide range of advanced heuristic and statistical analysis tests on email headers and body text including text analysis, Bayesian filtering, DNS blocklists, and collaborative filtering databases.  

While SpamAssassin works very well and greatly reduces the amount of spam a user receives it is unable to catch everything due to its passive nature. When users experience higher levels of spam or specific spam targeting, an active spam filtering system is a great way to provide a higher level of protection. 


Zipline utilizes an additional active spam filtering service called SpamHero for users that need a deeper level of filtering.  For an additional $120/year, you can add a powerful layer of spam protection on top of your existing SpamAssassin service. Their team is constantly working to reduce spam tracking over 100 million senders and adding thousands of new filtering rules each day. This active approach allows the service to capture and prevent even the latest spam techniques. This additional service adds:
  • Human spam review
  • Over 22 million filter rules
  • Sender reputation tracking
  • Domain wide filter policies
  • Email archiving
If no amount of email settings changes seem to make a difference in the volume of spam email that you're receiving, you have the option to request that Zipline add SpamHero to your email domain. Your email account is already set up to guard against spam, but in cases involving large amounts of spam emails, adding this 3rd party spam filter will give you the boost you need to protect you against spam.

 is applied across your entire email domain, no matter how many email addresses are listed under your email domain. The 100,000 inbound messages per month plan, which is the most cost effective option and is sufficient for most of our SpamHero clients, costs $120 per year. If you're interested in taking a more active approach to combatting spam you can contact Zipline support at today to get a 30-day free trial started.
