Overview
Unlock the power of post-purchase engagement by connecting Route Returns with Klaviyo. Automatically feed return and exchange data into Klaviyo to send customized email and SMS flows or get clever with segments and analytics. Perfect for building stronger customer relationships and maximizing ROI on every interaction.
1. Why Integrate Route Returns with Klaviyo?
- Seamless workflow: Every return event in Route Returns translates into a Klaviyo metric, enabling tailored flows based on real-time return behavior.
- Full data transparency: Access tracking updates, outcomes (refunds, exchanges, store credit), and product details - rich data for building smarter campaigns.
- Advanced customization: Build flows and segments that go beyond the basics. Win back customers with fit‑related returns, remarket store credits, or exclude frequent returners from promos.

2. How It Works
- A customer initiates a return through Route Returns.
- That return becomes a custom metric in Klaviyo, linked by email to the user profile (new profiles are created if needed).
- Each event includes detailed data: return ID, shipping & tracking info, outcome, product name/SKU/image, and more, for fine-grained automation.
3. Getting Set Up
Step-by-Step Setup
- Locate your Klaviyo API Key: Log in to Klaviyo > go to Settings > API Keys.
- Enable Route Returns integration: Inside your Route Returns admin, head to Settings > Integrations > Klaviyo, toggle on the integration, and paste the API key.
Note: If the API key field is greyed out, reach out to your account manager or support team for help.
4. What You Can Do Next
Recreate Notification Emails in Klaviyo
Replace Route Returns' default notifications with fully branded, Klaviyo-powered emails. Once your flows are live, remember to disable the old ones in Route Returns to avoid duplicate sends.


Build Custom Flows & Segments
Let data drive your messaging:
- Trigger flows and nudge customers with tailored recommendations.
- Encourage usage of store credit with timely email reminders.
- Segment high-return-volume shoppers to improve marketing efficiency.
- Enrich existing Klaviyo flows such as abandoned cart or browse abandonment with return-policy info blocks.


5. Plan & Support Information
The integration is available to all Route merchants
