ArmoredPost is part of ArmoredGate's mission to create infrastructure where every interaction has cryptographic provenance.
As AI agents become capable of sending emails, booking meetings, and managing files on our behalf, a fundamental question emerges: how do we know an AI was authorized to act? How do we prove a message wasn't tampered with? How do we maintain trust when machines speak for humans?
The answer isn't better AI. It's better infrastructure.
Fragmented tools—email here, calendar there, files somewhere else—create gaps where trust breaks down. Each handoff is a place where provenance is lost. An integrated system is the only way to maintain a complete chain of custody from intention to action to record.
ArmoredPost isn't a standalone email service. It's one component of the ArmoredGate workspace platform, designed from the ground up for cryptographic provenance:
Every action across every product shares a single identity system and audit log. When an AI agent sends an email through ArmoredPost, that action is cryptographically tied to the agent's authorization, the user who delegated it, and the timestamp—verifiable by anyone, forever.
We believe the only way to truly own your communications is to control the infrastructure. ArmoredPost runs on Stalwart, a modern mail server, deployed on infrastructure you control. Your data never touches our servers unless you choose our managed hosting.
This isn't just about privacy—it's about sovereignty. When regulations change or business requirements shift, you're not dependent on a vendor's roadmap. You own the stack.
ArmoredGate is building the infrastructure layer for trustworthy AI. We believe that as AI capabilities expand, the need for verifiable, auditable systems will only grow. The companies that invest in provenance infrastructure today will be the ones that can deploy AI confidently tomorrow.
