World, Meet Abusix Mail Intelligence

5 December 2018

Today we’re excited to announce the launch of our latest intelligence service for email providers – the Abusix Mail Intelligence service. If you have been in the email business for some time, you may be wondering – Is it just another blacklist? Why should I care? Let us explain.

Marketers have declared that email marketing is hands down, the most profitable channel for marketing, generating about $40 for every $1 spent. It’s no wonder that there are over 200 Billion (with a B) email messages sent across the internet every single day.

A lot of those are legitimate messages that legitimate people and companies send to carry out their business or send across their personal communication. But unfortunately studies show that more than 85% of all emails sent today are SPAM messages.

Given the high amount of unwanted messages being sent every day, any email provider, whether it’s an ESP (email service provider), or a large corporation managing their own email service, has to deal with it. And they do try, but these message do slip through the cracks every now and then. Moreover, these providers are not just the recipients of these messages, but are also senders of messages. Any bad activity in their network, whether it is intentional by bad actors or is just an ignorant customer violating use policies, can affect their ability to send emails, and most of the times there is nothing they can do about it.

This is why we built the Abusix Mail Intelligence service. It gives more control, visibility and peace of mind to the email providers. To understand how, let’s look at the typical challenges that email providers face and how Abusix Mail Intelligence service solves them:


1. Not All Blacklists Are Created Equal

There are a lot of blacklists out there, and we mean a lot. These are created by large, reputable businesses, as well as small lesser knowns, and even fraudsters. Since pretty much anyone can create a blacklist, they cannot always be trusted. Consequently, a lot of them are not widely used by email providers.

Every blacklist is different – depending on their geographic location, and the type of data they collect through their trap networks. As such, these lists are bound to miss threats that don’t get reported to them. And so, it makes sense for email providers to subscribe to multiple such blacklists to improve their accuracy of detecting and purging unwanted messages.


Did you know? Abusix’s trap network is the 3rd largest MX Destination in the world.


The Abusix Mail Intelligence (formerly Zetascan) service aggregates, processes and normalizes data from many of the best providers, facilitating a real-time lookup of IP, Domain and URL threat data for various applications and services. And according to a recent Virus Bulletin report, Abusix Mail Intelligence has the best catch rates in the industry:

  1. Spam Catch Rate – 99.02%
  2. Malware Catch Rate – 99%

2. Complexity Related to Accessing and Using Threat Data

Most Email Service Providers use multiple blacklists to filter out unwanted and dangerous messages before delivering them to their user’s inboxes. Simply put, a blacklist is a list of IPs or domains that a blacklist operator has found to send spam, is infected with malware or has some recently reported activity that indicates malicious intent. The providers use this information from various blacklist services along with internal metrics to make decisions on whether or not to block a message. It’s needless to say that the accuracy of decisions the email provider makes is highly dependent on:

  1. The type of data they receive – this is typically mitigated by subscribing to multiple threat data feeds and blacklists
  2. Their ability to process millions of threat indicators they receive from their threat feeds – if they cannot handle the traffic, they stay vulnerable till the point they can catch up

Abusix Mail Intelligence (AMI) reduces the complexity related to accessing and using threat data by consolidating essential, industry-leading threat feeds into one easy-to-consume service. AMI natively contains mechanisms which grade IP addresses and domains for anti-spam measures and delivers trustworthy results with very high reliability and low false-positives. This allows for informed and accurate decision making for enterprises and email providers.

Moreover, Abusix Mail Intelligence (AMI) blocks real-time emerging threats in less than 10 seconds, unlike competitors who are delayed by 10 minutes or more.


3. If Flagged, Getting Delisted is a Nightmare

Service providers cannot always control who in their network may violate the use-policies and are likely to get flagged for bad activity at some point. Once an IP address has been blacklisted, as an example, a typical process to get delisted includes visiting the blacklist's website and doing a lookup on the IP address. Each blacklist database has its own criteria for flagging IP addresses and compiling its own list of online offenders. Most blacklist databases will provide general listing reasons, but don't list the specifics which can help resolve the issue and get delisted.

At Abusix, we believe in transparency. And transparency means:

  1. Providing full visibility to the email provider to see why their IP was blacklisted – you will know what we know.
  2. Providing tools to delist once actions are taken to remediate the issue.
