Best Klaviyo Integrations for Ecommerce (2026)

Quick answer: The best Klaviyo integrations connect the rest of your stack so its data powers your emails — reviews (Yotpo, Okendo, Judge.me), subscriptions (Recharge), helpdesk (Gorgias), loyalty (Smile.io, LoyaltyLion), and your ecommerce platform (Shopify, WooCommerce, BigCommerce). Klaviyo has 350+ integrations; the right ones depend on your business model, but reviews and your platform integration are near-universal wins.

Key takeaways

• Integrations make Klaviyo’s data richer, which makes your flows smarter.
• Reviews and your platform integration are essential for almost every store.
• Subscriptions, helpdesk, and loyalty integrations matter based on your model.
• Klaviyo has 350+ integrations — choose by need, not by count.
• Each integration should feed a segment or flow, or it’s just clutter.

Klaviyo is most powerful when it’s the hub of your ecommerce stack. Here are the integration categories worth connecting and how to choose. This complements our complete Klaviyo flows guide.

Why integrations matter

Every integration adds data Klaviyo can segment and trigger on. Connect your reviews app and you can email people who left 5 stars (or chase those who haven’t). Connect your subscription tool and you can trigger flows on renewals and churn. The point isn’t to install many apps — it’s to feed Klaviyo the signals that make your flows more relevant.

Reviews and UGC (Yotpo, Okendo, Judge.me)

Reviews are a flywheel: collect them in your post-purchase flow, then sync the ratings and photos back into Klaviyo to use as social proof in welcome and promo emails. This is a near-universal integration — connect a reviews app early.

Subscriptions (Recharge, Smartrr, Skio)

If you sell subscriptions, integrate your subscription platform so you can trigger flows on upcoming renewals, failed payments (dunning), and cancellations. Reducing involuntary churn with a well-timed dunning flow often pays for the whole stack.

Helpdesk (Gorgias, Zendesk, Re:amaze)

Connecting your helpdesk gives Klaviyo and your support team a unified view of the customer — support history informs segmentation, and you can suppress promotional sends to someone with an open complaint. It keeps your email respectful of context.

Loyalty and rewards (Smile.io, LoyaltyLion)

Loyalty integrations let you trigger flows on points balances, tier changes, and reward expiry — powerful for VIP retention. Email the customer who’s 50 points from a reward, or remind them before points expire.

Platform integrations (Shopify, WooCommerce, BigCommerce)

Your ecommerce platform integration is the foundation — it’s what syncs orders, products, and events. We have dedicated setup guides for WooCommerce, BigCommerce, Magento, and the existing Shopify integration guide. Get this one right before adding others.

How to choose your integrations

Apply one test to every integration: does it feed a segment or a flow? If connecting it lets you target or trigger more precisely, it earns its place. If it just adds another dashboard, skip it. Start with reviews and your platform, then add subscriptions, helpdesk, or loyalty based on your model.

Setup tips

• Connect via official integrations where available — they’re more reliable than custom API work.
• Map the data to a use case before you build the flow, so you know which property you’re triggering on.
• Test the sync with a single profile before relying on it for sends.

Frequently asked questions

What are the best Klaviyo integrations?

For almost every store: a reviews app (Yotpo, Okendo, Judge.me) and your ecommerce platform integration. Then add subscriptions (Recharge), helpdesk (Gorgias), or loyalty (Smile.io) based on your business model. Klaviyo has 350+ integrations to choose from.

How many integrations does Klaviyo have?

Klaviyo offers 350+ integrations across reviews, subscriptions, helpdesk, loyalty, surveys, ads, and ecommerce platforms. The goal is to connect the few that feed your segments and flows, not to install as many as possible.

Yes. The Recharge integration lets you trigger Klaviyo flows on subscription events like upcoming renewals, failed payments, and cancellations — useful for reducing churn with dunning and retention flows.

How do I choose which Klaviyo integrations to use?

Ask whether the integration feeds a segment or a flow. If it lets you target or trigger more precisely, connect it; if it only adds another dashboard, skip it. Start with reviews and your platform integration.
