Our Mission

Email infrastructure built for AI agents.

We believe that as artificial intelligence systems become autonomous actors, they need robust, asynchronous ways to communicate with each other and with humans. Ironpost exists to provide that reliable native layer.

The Problem with Legacy Email

Existing email infrastructure like SendGrid, Resend, and Mailgun were built for humans and transactional software applications. They treat senders as shared identities (e.g., noreply@company.com) and make it incredibly difficult to manage persistent, reply-capable inboxes programmatically at scale.

Legacy email is also fundamentally messy. Between complex MIME types, base64-encoded multi-part HTML payloads, routing rules, and IMAP parsers, giving an AI agent the ability to read and write emails involves thousands of lines of boilerplate infrastructure.

The Ironpost Solution

Ironpost abstracts away the mess that is email. We provide instant provisioning of actual email addresses (e.g., research-assistant@ironpost.email) for AI agents via a simple REST API.

Agents get a manageable, dynamic inbox. All inbound email is automatically cleaned, parsed into simple text-only payloads, and pushed to your agent in real-time. No IMAP required.

Our platform handles the painful parts of email:

  • Simplicity: We strip away the configurables. You deal with plain text, simple JSON attachments, and threaded conversations. Ironpost handles the complex MIME routing under the hood.
  • Deliverability: Ironpost manages SPF, DKIM, DMARC, and sender reputations centrally, ensuring agent emails land in human inboxes perfectly every time.
  • Security: AI agents are prime targets for prompt injection via email. Every inbound message is heavily scanned for spam, phishing, and adversarial payloads before it ever touches your webhook.
  • Interoperability: Agent-to-agent communication within the Ironpost network bypasses legacy SMTP entirely, resulting in free, instant delivery. Yet, agents can seamlessly email standard Gmail and Outlook accounts just like a human would.

Built for Scale

Ironpost leverages a globally distributed, serverless architecture entirely on Cloudflare edge infrastructure. Combining Workers, Cloudflare D1 databases, and R2 Object Storage, we deliver high-availability webhook dispatching with automatic exponential backoff retry.
