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 Hunter account
- A Relevance AI account with access to your workspace
- Authorization (connect securely via API keys—no sensitive info stored manually)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your Hunter data. Relevance AI handles API operations (like GET, POST, PUT, DELETE) in the background—so you don't have to worry about authentication tokens, request formatting, or rate limits.
Built-in validation and error handling ensure your email verification and domain search workflows run smoothly.
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 Hunter + Relevance AI integration without writing code:
- Verify email data quality: Ensure domain names and email formats are correctly formatted.
- Use batch processing: Group email verification requests to optimize API usage and performance.
- Monitor usage limits: Track your Hunter API requests to stay within your plan's constraints.
- Validate credentials: Double-check OAuth authentication settings before running automated workflows.
- Handle responses properly: Implement error handling for unverified or invalid email addresses.
