An uptime percentage of at least 98% during the service term is pledged in our SLA.

This is one of the main benefits of using a blacklist – we help protect your organization from all forms of email abuse and new emerging email-borne threats. But generally speaking, blacklists have one major job, which is to protect your network and mail servers from spam.

We provide both live chat and email support to customers and those with listing issues.

For customers using Abusix Mail Intelligence to reject mail, we ask that any rejection uses the text we provide, including the delisting URL.

If you find yourself listed on one of our blacklists, you can directly go to our lookup page and follow the instructions there, or you go to our customer portal to delist your IPs.



Abusix uses industry-standard practices for its security controls; including, but not limited to firewalls, intrusion detection, change management, and written security policies.

Security at Abusix follows the ISO/IEC 27002:2013 standard.

For Abusix Mail Intelligence, we set up three different tiers here.

In order to calculate the most accurate price for you, we need to see how many queries you’re doing on a 10-day average.
That’s why all our tiers start out with a free 14-day trial, which lets you and us know how many queries you’re going to need to properly protect your mail servers.
It roughly equals the number of messages received per day but can be more, depending on the content and the lists you’re querying.


AbuseHQ (AHQ) employs a public cloud deployment model using virtualized resources, as a software-as-a-service (SaaS) solution. AbuseHQ is hosted at Amazon Web Services in Germany or the USA; which operates as ISO Certified Data Centers under German and US Privacy Laws respectively.

The most common causes are: compromised accounts, compromised WordPress servers, abused webforms, and abused sign-up forms.
