The Problem

Fragmented tools break the chain of trust

🔗

No Audit Trail

When email, calendar, and files live in separate systems, there's no unified record of who said what, when.

🤖

AI Can't Prove Authenticity

AI agents sending emails through third-party services have no cryptographic proof of origin or authorization.

🔓

Trust Assumptions Everywhere

Every integration point is a place where messages can be forged, modified, or lost without detection.

The Solution

An integrated system is the only path to true provenance

ArmoredPost isn't just an email service—it's part of a unified workspace where email, calendar, drive, and support share a single identity and audit system.

  • ✓ Every message cryptographically signed with DKIM
  • ✓ Multi-domain support with per-domain keys
  • ✓ Self-hosted on your infrastructure
  • ✓ API-first for AI agent integration
  • ✓ Unified audit log across all workspace products
// Send email with provenance
POST /v1/send
{
"from": "agent@yourco.com",
"to": "client@example.com",
"subject": "Invoice #1234"
}
// Response includes provenance
{
"message_id": "<abc@yourco.com>",
"dkim_signed": true,
"audit_id": "aud_7x9k..."
}

AI-Ready Infrastructure

An integrated system is the only way to ensure provenance for every interaction with AI

When AI agents send emails on your behalf, you need proof. Proof that the agent was authorized. Proof that the message wasn't tampered with. Proof that ties back to a verifiable identity. ArmoredPost provides that chain of custody—from AI action to delivered message to audit record.
