Our Story
I spent 15 years in email deliverability, helping companies dig out of spam folder purgatory. The same problems came up over and over: outdated suppression lists, no centralized management, and affiliates sending to addresses they shouldn't.
I built List Armor because I wanted the tool I wished existed. A single source of truth for suppression data, with an API fast enough to check every email in real-time and a portal that makes affiliate compliance monitoring painless.
The core problem hasn't changed in 15 years: if your affiliates send to people who've opted out, your sender reputation takes the hit. List Armor gives you the visibility and tools to catch violations before they damage your deliverability.
Our Values
Security First
Your suppression lists contain sensitive data. We treat it that way. Encrypted at rest and in transit, never shared.
Developer Friendly
Clean APIs, comprehensive docs, SDKs in every major language. Integration should take hours, not weeks.
Compliance Focused
We help you stay compliant with CAN-SPAM, CASL, and other regulations. Audit logs for everything.
Always Available
99.9% uptime SLA backed by multi-region infrastructure. Your compliance checks can't wait.

Jeremy Yunis
Founder & CEO
I've spent over 15 years in email deliverability and compliance, working across affiliate networks, ESPs, and in-house email programs. I founded List Armor after seeing too many legitimate senders struggle with fragmented suppression list management and preventable compliance issues.
My mission is simple: give email senders the tools they need to monitor affiliate compliance and protect their sender reputation. I built List Armor to solve the problems I dealt with every day in the field.
