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 Sendfox 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 Personal Access Token authentication, ensuring only authorized workflows access your Sendfox data. Relevance AI handles API operations (like GET, POST, PUT, DELETE, PATCH) in the background—so you don't have to worry about errors, formatting, or limits.
Built-in validation and type conversion ensure your workflows run smoothly, even when managing contacts and lists across Sendfox.
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 Sendfox + Relevance AI integration without writing code:
- Organize your contacts: Maintain clean contact lists with proper segmentation and tags.
- Use authentication wisely: Keep your personal access token secure and regularly rotate credentials.
- Validate data formats: Ensure email addresses and contact information meet Sendfox requirements.
- Monitor API usage: Stay within Sendfox's rate limits and implement proper error handling.
- Test campaigns first: Verify automations with small test lists before full deployment.
