What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Mailrefine account
- A Relevance AI account with access to your projects and datasets
- Authorization (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your Mailrefine data. Relevance AI handles API operations through authorized requests to the Mailrefine API—so you don't have to worry about authentication tokens, headers, or request formatting.
Built-in validation and response handling ensure your email verification workflows run smoothly, even with complex data structures.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

Best Practices for Non-Technical Users
To get the most out of the Mailrefine + Relevance AI integration without writing code:
- Authenticate properly: Ensure OAuth credentials are correctly configured for secure API access.
- Structure API requests: Use clear path parameters and appropriate HTTP methods for each endpoint.
- Validate responses: Monitor response status codes and body content for successful operations.
- Handle rate limits: Implement appropriate delays between API calls to avoid throttling.
- Test endpoints: Verify API paths and payloads in a test environment before production use.
