Verify emails in your n8n workflows automatically
n8n doesn't need a custom node β RocketVerifier's REST API drops straight into an HTTP Request node. Verify each lead the moment it enters your workflow (form submit, CRM webhook, scraper output) and branch on the result before it reaches your CRM or outbound tool.
Example, inside n8n:
n8n calls RocketVerifier's verification API for you and hands back a clean, classified result — no dashboard upload, no manual CSV round-trip.
Connect n8n in 3 Steps
Takes about two minutes. 100 free credits included so you can try it before you pay for anything.
Get an API key
Sign up free and grab a key from the RocketVerifier dashboard β claim 100 free trial credits with a quick card check.
Add an HTTP Request node
Point it at /v1/verify with your API key in the Authorization header and the leadβs email in the body.
Branch on the result
Use an IF node on the classification field to route valid, risky, and invalid leads to different next steps.
HTTP Request node configuration:
Method: POST
URL: https://api.rocketverifier.com/v1/verify
Headers: Authorization: Bearer rv_live_your_api_key
Content-Type: application/json
Body: { "email": "{{ $json.email }}" } Full setup guides are in the MCP documentation and API reference.
Confidence scores, not guesses
Every result comes back with a 0–100 score and evidence — SMTP response, provider detection, DNS records — so n8n can make the send/skip call.
Idempotent by default
Every write request auto-generates an Idempotency-Key, so a retried or automated call can never double-charge credits or create duplicate jobs.
Never pay for a non-answer
Unknowns and duplicates are always free — unlike incumbents that charge for "risky" or "unknown" results your workflow can't act on.
Common Questions About n8n + RocketVerifier
Is there an official n8n node for RocketVerifier?
The REST API works directly with n8nβs built-in HTTP Request node β no custom node install required. See our n8n integration guide for a ready-to-import workflow.
Can I verify a whole list, not just one email at a time?
Yes. For bulk lists, call POST /v1/verify/bulk once with the full array of emails, then poll GET /v1/jobs/{jobId} until it completes.
What does the API return?
A classification (valid, invalid, risky, unknown), a 0β100 confidence score, and evidence like SMTP response and provider detection β enough to branch your workflow with confidence.
