n8n Integration

Overview

n8n is a free and open-source workflow automation tool that lets you connect APIs and services visually. With BounceRaptor's MCP server, you can add email verification steps to any n8n workflow using the HTTP Request node.

Prerequisites

Step 1: Get Your MCP Key

Navigate to Settings → MCP Keys in your BounceRaptor dashboard. Create a new MCP key with the description "n8n Integration". Copy the key — you'll need it in the next step.

Step 2: Add an HTTP Request Node

In your n8n workflow, add an HTTP Request node and configure it as follows:

Authorization: Bearer YOUR_MCP_KEY
Content-Type: application/json

{
  "email": "{{ $json.email  }}"
}

Step 3: Parse the Response

The API returns a JSON object with the verification result. You can use n8n's Set or IF node to branch based on the result:

{
  "email": "[email protected]",
  "status": "valid | invalid | catch_all | unknown",
  "syntax_valid": true,
  "mx_valid": true,
  "smtp_verified": true,
  "is_spam_trap": false,
  "is_role_based": false,
  "provider": "Google Workspace"
}

Step 4: Build Your Workflow

Example workflow: verify a list of emails and route valid ones to your mailing list, while flagging invalid ones for review:

1. Trigger: Manual or scheduled trigger with email list input
2. Split In Batches: Process emails one at a time
3. HTTP Request: Call BounceRaptor verify-email endpoint
4. IF Node: Check if status === "valid"
5. True branch: Add email to mailing list / CRM
6. False branch: Log or flag invalid emails for review

Rate Limits

Your n8n workflows share the same API rate limits as your BounceRaptor plan. Add a Wait node between batches if you need to throttle requests.
