n8n email verification with ValidReach
Verify emails in n8n workflows using the ValidReach community node (n8n-nodes-validreach) or standard HTTP Request nodes before CRM and ESP actions.
How it works with n8n
Connect via HTTPS webhooks, automation runners (n8n, Make, Zapier), or CSV/XLSX batch exports.
- 1
Add a ValidReach verification step inside n8n right after any trigger that collects or updates an email address.
- 2
Call POST https://validreach.dev/api/v1/verify/single with Authorization: Bearer YOUR_API_KEY.
- 3
Branch the workflow on data.status (valid, invalid, disposable, catchall, role, unknown).
- 4
Pass verified contacts to your ESP or CRM and log rejected addresses to an audit sheet or Slack channel.
When to use ValidReach with n8n
Three common patterns teams deploy to stop hard bounces and protect domain reputation.
Protect n8n sender reputation
Remove hard-bouncing and deactivated mailboxes before n8n dispatches newsletters, lifecycle flows, or announcements.
Real-time signup & webhook verification
Validate new addresses at capture so typos and disposable domains never enter your n8n audience.
Scheduled list re-verification
Audit aging n8n segments before seasonal campaigns using bulk CSV/XLSX verification with full column preservation.
Mapping ValidReach fields into n8n
Call POST /api/v1/verify/single from your webhook or workflow runner and route contacts based on the returned status.
POST https://validreach.dev/api/v1/verify/single
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
{
"email": "contact@example.com"
}validreach_status | Recommended n8n Action |
|---|---|
| valid | Allow into active n8n campaigns & flows |
| catchall / role | Tag for low-volume sending or manual review |
| unknown | 0 credits billed; retry later or require opt-in click |
| invalid / disposable | Suppress or reject before n8n send |

n8n email verification questions
- Does ValidReach require a native plugin inside n8n?
- No. ValidReach connects to n8n through standard HTTPS webhooks, our REST API (POST /api/v1/verify/single and /api/v1/verify/file), or automation runners such as n8n, Make, and Zapier—so you can inspect and control every field mapped into n8n.
- How should I handle catch-all or unknown results in n8n?
- Route confirmed valid addresses directly into active n8n flows, suppress invalid and disposable addresses immediately, and tag catchall or unknown records for low-volume sending or a later retry. ValidReach never charges credits for unknown results.
- Can I verify an existing n8n export without losing custom columns?
- Yes. Upload your n8n CSV or .xlsx export to /dashboard/lists or POST /api/v1/verify/file, then download results with include_original=true to keep every original n8n column alongside the verification status and reason code.
- What is the fastest way to automate n8n verification?
- Use n8n's built-in HTTP Request module (or the n8n-nodes-validreach community node in n8n) to call POST https://validreach.dev/api/v1/verify/single with your Bearer API key.
