To get the most out of the Klaviyo + Relevance AI integration without writing code:
- Start with a clean Klaviyo account: Organize your lists and ensure consistent naming conventions for easy management.
- Use pre-built workflows: Relevance AI provides templates for managing lists and adding members, making it easy to get started.
- Connect securely: Ensure you use valid OAuth credentials and approve the correct Klaviyo account during setup.
- Test before scaling: Run your automations with a small subset of data to identify any issues before applying them to larger lists.
- Monitor API usage: Keep an eye on your API call limits and implement batching to avoid hitting rate limits.
