n8n-nodes-billionverify

This is an n8n community node. It lets you use BillionVerify email verification in your n8n workflows.

BillionVerify validates email addresses in real time — checking syntax, MX records, and live SMTP mailboxes — and flags disposable, catch-all, and role-based addresses so you can clean lists and stop bounces before they hurt your sender reputation.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

In short, from the n8n UI: Settings → Community Nodes → Install and enter:

n8n-nodes-billionverify

Operations

| Operation | Description | Credits | | --- | --- | --- | | Verify Email | Validate a single email address in real time. Returns status (valid, invalid, risky, catchall, role, disposable, unknown), deliverability, score, MX data, and the reason. | 1 credit (0 for unknown) | | Verify Emails (Bulk) | Validate up to 50 email addresses in one synchronous call. Each email is emitted as a separate output item. | 1 credit per email | | Check Disposable | Detect whether an email uses a disposable/temporary domain. In-memory lookup only. | Free |

For lists larger than 50 emails, use the asynchronous file verification API (CSV/XLSX upload + webhook callback). It is on the roadmap for this node; in the meantime call it directly via the HTTP Request node — see the API docs.

Use with AI Agents

This node is exposed as an AI tool (usableAsTool). Attach it to an n8n AI Agent and the agent can verify email addresses on demand — e.g. "clean this list of leads before adding them to the CRM."

Credentials

You need a BillionVerify API key.

1. Sign up at billionverify.com.
2. Go to Dashboard → API Keys and create a key (it starts with sk_).
3. In n8n, create new BillionVerify API credentials and paste the key.

The credential test calls the free disposable-check endpoint, so validating your key costs no credits.

Usage

A common pattern: Webhook (form submission) → BillionVerify (Verify Email) → IF is_deliverable is true → add to CRM, otherwise route to a review branch.

The single-verify response looks like:

{
  "email": "[email protected]",
  "status": "valid",
  "score": 0.95,
  "is_deliverable": true,
  "is_disposable": false,
  "is_catchall": false,
  "is_role": false,
  "domain": "example.com",
  "reason": "smtp_deliverable",
  "credits_used": 1
}
