Outbound Email Abuse Intelligence Platform for Mailserver Operators
C6/10April 16, 2026
WhatA collaborative threat intelligence network where self-hosted mail server operators share real-time data on spam and abuse originating from major providers, generating aggregate pressure and automated abuse reports that providers cannot ignore.
SignalIndividual operators running their own mail infrastructure are powerless when spam floods in from Google and Microsoft IPs — they can't block the entire provider, their individual complaints are ignored, and they have zero leverage despite clear log evidence of abuse.
Why NowThe consolidation of email into three mega-providers (Google, Microsoft, Salesforce/Mailchimp) means abuse from these platforms is now the dominant spam vector, and traditional blacklists are useless against them since blocking Gmail would cut off legitimate mail.
MarketSelf-hosted email administrators, MSPs, and email security vendors; tens of thousands of organizations running their own mail infrastructure; adjacent to the ~$4B email security market; no one aggregates abuse data specifically to hold senders accountable.
MoatNetwork effect — the more mail operators contributing log data, the stronger the signal and the harder for providers to ignore; proprietary abuse pattern database becomes uniquely valuable over time.
