n8n Form email verification questions
- Does ValidReach require a native plugin inside n8n Form?
- No. ValidReach connects to n8n Form 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 Form.
- How should I handle catch-all or unknown results in n8n Form?

- Can I verify an existing n8n Form export without losing custom columns?
