Klaviyo integration — live
Klaviyo AI recommendations from Shopify predictions
Flexsee pushes per-recipient product picks into Klaviyo via Flexsee Campaign Send events — so post-purchase, win-back, and campaign emails show what each customer is predicted to buy next, not store-wide bestsellers.
Outbound only. No Klaviyo data pulled back. Consent enforced before every send.
“A ‘You might also like’ block with the same four products for everyone is merchandising. Per-customer picks from your order data is prediction.”
Flexsee ranks products for each profile from models trained on your Shopify catalog and purchase history.
The Flexsee Campaign Send metric
Flexsee does not send bulk email itself. From Wizard Flow, it fires one Klaviyo Track event per opted-in recipient. Your Klaviyo flow listens for Flexsee Campaign Send and delivers the message.
Each event carries AI-ranked products in flexsee_recommendations — title, image, URL, price, and rank — ready to render in your Klaviyo HTML template.
Key event properties
- event.subjectEmail subject from Wizard Flow
- event.flexsee_recommendationsArray of ranked products per recipient
- event.flexsee_has_recommendationsHide block in template when empty
- event.first_namePersonalization fields
Each recommendation includes productId, title, imageUrl, url, price, and rank.
How Flexsee + Klaviyo works
Predict in Flexsee. Deliver in Klaviyo. You control the flow design and brand — Flexsee supplies the intelligence.
| Step | Where | What happens |
|---|---|---|
| 1 | Flexsee | Train a model on Shopify orders and catalog |
| 2 | Flexsee | Connect Klaviyo (private API key, outbound only) |
| 3 | Klaviyo | Create a flow triggered on Flexsee Campaign Send |
| 4 | Flexsee | Wizard Flow: pick predictive audience, subject, products per recipient (2–6) |
| 5 | Flexsee → Klaviyo | One Track event per recipient with flexsee_recommendations |
| 6 | Klaviyo | Flow delivers personalized email from your template |
Flexsee vs generic Klaviyo product blocks
| Approach | Personalization | Data source |
|---|---|---|
| Flexsee Campaign Send | Different products per recipient, ranked by model | Your Shopify orders + trained Flexsee model |
| Static “bestsellers” block | Same products for everyone | Manual merchandising or aggregate sales |
| “Viewed product” dynamic block | Based on last browse, not predicted next purchase | Recent onsite behavior only |

Frequently asked questions
How does Flexsee send recommendations to Klaviyo?
Wizard Flow fires a Flexsee Campaign Send Track event per recipient. Each event includes flexsee_recommendations — AI-ranked products from your model. Your Klaviyo flow triggers on that metric and renders them.
Does Flexsee pull data from Klaviyo?
No. The integration is outbound only. Flexsee pushes events and recommendations; Klaviyo data is not synced back for training.
Do I need a Flexsee API key?
Not for Wizard Flow sends. You need a Klaviyo private API key in Flexsee Integrations. Flexsee API keys are only for custom server-side Predictions API calls.
How is marketing consent handled?
Wizard Flow only sends to profiles with email and marketing consent Flexsee can verify. Opted-out recipients are excluded before any event is fired.
Can I use this for post-purchase flows?
Yes. Use Flexsee Campaign Send for campaign-style sends, or enable event enrichment to attach recommendations to Klaviyo Placed Order events for automated post-purchase triggers.
