Authentication

Two supported authentication methods

API Key (Recommended)

Generate API keys from your dashboard. Pass them as a Bearer token in the Authorization header.

Authorization: Bearer sk_live_abc123...

Session Auth

For browser-based integrations. Authenticate via the web login and use session cookies with CSRF tokens.

Cookie: ractermx_session=abc123; X-CSRF-TOKEN: ...

Send an Email in Seconds

The RacterMX API follows RESTful conventions. JSON in, JSON out. All endpoints live under /api/v2/ and require authentication.

  • Base URL: https://ractermx.com/api/v2
  • Content-Type: application/json
  • Rate limit: 100 requests/minute
  • All timestamps in UTC (ISO 8601)
# Send an email via the RacterMX API
curl -X POST https://ractermx.com/api/v2/emails/send \
  -H "Authorization: Bearer sk_live_abc123" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "hello@yourdomain.com",
    "to": ["user@example.com"],
    "subject": "Hello from RacterMX",
    "html": "<h1>It works!</h1>"
  }'

# Response
{
  "success": true,
  "message_id": "<abc123@yourdomain.com>"
}

API Endpoint Reference

100+ endpoints covering domains, aliases, DNS zones, email sending, webhooks, blocklists, SMTP credentials, DMARC analytics, reputation monitoring, alerts, security posture, and more. All documented with interactive try-it-out.

MCP Server for AI Agents

Let AI manage your email forwarding through natural language

Model Context Protocol

The RacterMX MCP server exposes 110+ tools that AI agents can call. Connect it to Claude, ChatGPT, or any MCP-compatible client to manage domains, aliases, DNS zones, security posture, DMARC, alerts, and more conversationally.

  • Manage domains, aliases, and DNS zones
  • Monitor security posture and DMARC compliance
  • Track outbound email reputation
  • Configure alert rules and webhooks
  • Search and filter email logs
  • Manage organizations, tags, and SMTP credentials
// Add to your MCP client config
{
  "mcpServers": {
    "ractermx": {
      "command": "npx",
      "args": ["-y", "@ractermx/mcp-server"],
      "env": {
        "RACTERMX_API_KEY": "sk_live_abc123"
      }
    }
  }
}

// Then ask your AI agent:
"List all my domains on RacterMX"
"Create an alias catch-all@mydomain.com"
"Show me email logs from the last hour"

Terraform Provider

Manage your email infrastructure as code

Infrastructure as Code

The official RacterMX Terraform provider lets you provision and manage every aspect of your email infrastructure declaratively. Version your domains, aliases, DNS records, alerts, and security policies alongside the rest of your infrastructure.

  • 15 resources: domains, aliases, zone records, alerts, organizations, tags, and more
  • 10 data sources: security score, DMARC compliance, reputation, statistics, quotas
  • Full lifecycle: create, read, update, delete, import
  • GitOps friendly with state-driven drift detection
