How to Test Klaviyo Flows

Quick summary

Testing Klaviyo flows lets you validate email automation logic and message content against a controlled test audience before activating for all subscribers. By using entry conditions, audience segmentation, and preview tools, you can confirm your flow behaves correctly without exposing real customers to unfinished campaigns.

Steps

1. Adjust the entry conditions to define which test contacts will enter the flow.
2. Set your audience parameters for testing — use narrower segments for clearer, more reliable test results.
3. Fine-tune your message content specifically for testing purposes.
4. Click 'Review and turn on' to check your flow settings before running your test.
5. Hit 'Preview' to see exactly what your test recipients will receive in their inboxes.
6. Click 'Review and turn on' again to confirm your test flow won't accidentally reach real customers.
7. Click 'Save' to lock in your test configuration before activation.
8. Your Klaviyo flow test is ready — monitor performance without affecting your entire audience.
