n8n + Kawaa
Verify emails inside your n8n workflows
n8n is a workflow automation tool you can host yourself. Call the Kawaa API from an HTTP Request node to verify addresses inside any workflow, then branch on the result.
What you can build
- Verify an address with an HTTP Request node in any workflow
- Branch on the result with IF or Switch nodes
- Work through large lists in batches, and back off when the API answers 429
- Keep n8n on your own servers; the verification itself runs in Kawaa's cloud

FAQ
Frequently asked questions
- Is there a native n8n node for Kawaa?
- Not yet. Use the HTTP Request node to call Kawaa's API; it works in any workflow today.
- Can I run this completely on-premise?
- n8n runs on-premise, but verification requests still go to Kawaa's cloud API for processing.
- How do I handle rate limits?
- Use n8n's SplitInBatches node to throttle requests. Authenticated API calls are limited per key and per plan; use Retry-After and X-RateLimit-* headers to back off when you receive a 429.
