Gork Mail: Email for AI Agents — Complete Guide to Agent Inboxes & MCP

When developers build autonomous AI agents, AI SDRs, or workflow bots, one of the first infrastructure requirements they encounter is providing the agent with a real, persistent email address.

Whether you search for Gork Mail or Grokmail, the goal is the same: giving AI agents rock-solid email capability without exposing your domain to reputation risk or prompt injection.

In this guide, we break down why standard transactional email providers (SendGrid, Mailgun, Postmark) fail for AI agents, and how Gork Mail provides dedicated email for AI agents over REST API and Model Context Protocol (MCP).

Why Standard Email APIs Fail AI Agents

Traditional transactional email APIs were built for static server-triggered events (e.g. password resets, purchase receipts). They were never designed for agentic, multi-turn, bidirectional email workflows.

When an AI agent uses a typical transactional provider, you face four core bottlenecks:

1. No Inbox Isolation: Transactional providers operate on domain keys rather than isolated agent mailboxes with independent quotas.
2. Complex Inbound Webhooks: Raw MIME payloads require manual parsing, threading, attachment extraction, and security sanitization before an LLM can consume them.
3. No Safety Guardrails: A looping agent can blast thousands of emails in minutes, burning your domain reputation or triggering carrier suspensions.
4. Lack of MCP Support: Developer agents (in Claude Code, Cursor, Windsurf) cannot easily interact with traditional APIs without custom wrapper code.

What is Gork Mail?

Gork Mail is email for AI agents — purpose-built developer infrastructure for autonomous agents, LLM applications, and agentic workflows.

Core Features

• API-Provisioned Inboxes: Create real email inboxes in milliseconds (POST /v1/inboxes or gork_create_inbox).
• Custom & Verified Domains: Provision inboxes directly under your enterprise domains (stripe.com, apple.com, cloudflare.com).
• Automatic Conversation Threading: Inbound and outbound emails are linked via RFC 5322 In-Reply-To and References headers, giving agents full thread history.
• Signed Webhooks: Real-time event notifications (email.received, email.sent, email.bounced) signed with HMAC-SHA256 (X-Gork-Signature).
• Native MCP Server: Ship email capabilities directly to Claude, Cursor, Goose, and LangChain via @gork/sdk.
• Server-Side Reputation Guardrails: Per-day sending caps, automatic bounce/complaint suppressions, bulk-send tripwires, and reputation circuit breakers.

Getting Started with Gork Mail in 3 Steps

1. Provision an Inbox via REST API

curl -X POST https://api.gork.email/v1/inboxes \
  -H "Authorization: Bearer $GORK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"username": "sales-agent-01", "domain": "stripe.com"}'

2. Connect via Model Context Protocol (MCP)

If you are using Claude Code or Cursor, add gork-mcp to your MCP settings:

{
  "mcpServers": {
    "gork": {
      "command": "npx",
      "args": ["-y", "-p", "@gork/sdk", "gork-mcp"],
      "env": {
        "GORK_API_KEY": "gork_live_YOUR_KEY"
      }
    }
  }
}

Now your AI assistant has 13 native email tools (gork_create_inbox, gork_read_emails, gork_send_email, gork_reply_email, gork_search_emails).

3. Handle Inbound Email via Signed Webhooks

When an email arrives, Gork mail delivers a sanitized payload to your webhook endpoint:

import { verifyGorkWebhook } from "@gork/sdk"

app.post("/webhooks/gork", async (req, res) => {
  const signature = req.headers["x-gork-signature"]
  const isValid = await verifyGorkWebhook({ payload: req.rawBody, signature, secret: process.env.GORK_WEBHOOK_SECRET })
  
  if (!isValid) return res.status(401).send("Invalid signature")

  const { event, payload } = req.body
  if (event === "email.received") {
    console.log(`New mail for agent ${payload.recipient}: ${payload.subject}`)
  }

  res.status(200).send({ ok: true })
})
