Duplicate Prevention Logic

KlavX is built to avoid duplicates and keep your Klaviyo data clean.

For Customer Profiles:

• We check if an email already exists in Klaviyo.

• If it does, we update the profile — not create a new one.

• Consent is re-checked each time to avoid marketing someone who opted out.

For Orders:

• We check the order ID before syncing.

• If the order already exists in Klaviyo, it’s skipped.

• Reattempts are logged if any errors occurred during the first try.

✅ This ensures you don’t get duplicated events or inaccurate revenue attribution in Klaviyo.
