If you’re running signup forms, CRM syncs, or list-building workflows through n8n, you’ve probably already got a spot where a bad email slips through and quietly tanks your sender reputation. We just shipped n8n-nodes-rocketverifier, an official community node that drops real-time and bulk email verification directly into your workflows.

Why a dedicated node instead of an HTTP Request node

You could always call the RocketVerifier API from a generic HTTP Request node — plenty of people already do. But a dedicated node gets you:

  • Typed operations (Verify, Create Batch Job, Get Status, Get Results, Check Credits) instead of hand-built URLs and JSON bodies
  • A proper credential type with a built-in test request against /v1/credits, so n8n tells you immediately if your API key is wrong
  • Cleaner workflow canvases — one RocketVerifier node instead of an HTTP Request node plus a Set node plus error-handling boilerplate

A dedicated node beats wiring HTTP Request nodes by hand.

Installing the node

In n8n, go to Settings → Community Nodes → Install and enter:

n8n-nodes-rocketverifier

Self-hosting instead? Install it directly into your n8n nodes directory:

cd ~/.n8n/nodes
npm install n8n-nodes-rocketverifier

Restart n8n and you’ll find RocketVerifier in the node panel.

Setting up credentials

Create a RocketVerifier API credential with your API key from Dashboard → API Keys. Use a sandbox key (rv_test_...) against @sandbox.rocketverifier.com addresses while you build the workflow — it exercises the real API without spending credits.

Operations available

Category Operation What it does
Email Verify Real-time single-address verification (1 credit)
Batch Job Create Submit a list of emails for async bulk verification
Batch Job Get Status Poll progress and summary counts
Batch Job Get Results Fetch paginated per-email results, filterable by classification
Credits Check Get current balance and today’s/this month’s usage

Three workflows worth stealing

1. Verify on signup. Trigger on a new Google Sheets row or Typeform submission → RocketVerifier: Verify → branch on status == "deliverable" before pushing the contact into Mailchimp or HubSpot. Kills bad signups before they ever reach your ESP.

2. Nightly list cleanup. Schedule trigger → pull your list from a database or sheet → RocketVerifier: Create Batch Job → wait/poll Get Status → Get Results → post a summary to Slack. Great for keeping a growing list clean without manual exports.

3. Credit monitoring. Schedule trigger (daily) → RocketVerifier: Check Credits → if balance is below a threshold, send yourself a Slack or email alert so you’re never caught mid-campaign with an empty tank.

Example: a minimal “verify on signup” workflow

Here’s the trimmed node graph for workflow #1 above, as it looks in an exported n8n workflow JSON (Set nodes for field mapping omitted for brevity):

{
  "nodes": [
    { "name": "Typeform Trigger", "type": "n8n-nodes-base.typeformTrigger" },
    { "name": "RocketVerifier: Verify", "type": "n8n-nodes-rocketverifier.rocketVerifier",
      "parameters": { "operation": "verify", "email": "={{$json.email}}" } },
    { "name": "IF status == deliverable", "type": "n8n-nodes-base.if",
      "parameters": { "conditions": { "string": [{ "value1": "={{$json.status}}", "value2": "deliverable" }] } } },
    { "name": "HubSpot: Create Contact", "type": "n8n-nodes-base.hubspot" }
  ]
}

The RocketVerifier: Verify node’s output includes status, score, and reason fields you can branch on directly — no parsing a raw HTTP response body.
