Our Story
List Armor was founded by email deliverability experts who spent years helping companies dig out of spam folder purgatory. We saw the same problems over and over: outdated suppression lists, no centralized management, and affiliates sending to addresses they shouldn't.
We built the tool we 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 management painless.
Today, we help companies of all sizes protect their sender reputation and stay compliant. Our team is united by a passion for email deliverability and a commitment to helping our customers succeed.
