To get the most out of the Kickbox + Relevance AI integration without writing code:
- Start with a clean email list: Ensure your contact list is organized and free of duplicates before verification.
- Use batch processing: Take advantage of batch email verification to efficiently process large lists and save time.
- Connect securely: Make sure to use OAuth credentials correctly to maintain secure access to the Kickbox API.
- Test with single verifications: Validate a few email addresses first to ensure your integration is working as expected before scaling up.
- Monitor API usage: Keep an eye on rate limits and implement error handling to manage requests effectively and avoid throttling.
