Klaviyo and Shopify: The Specific Integration Setup That Actually Works

The Klaviyo Shopify integration setup guide every DTC brand needs starts with one critical distinction: connected and working correctly are not the same thing. The default integration gives you the basics but leaves significant revenue on the table through misconfigured settings that most store owners never catch.

Switch transactional emails from Shopify to Klaviyo

Shopify sends order confirmations and shipping notifications by default. These are high-open-rate emails — 60 to 80 percent — and Shopify’s default versions do nothing with that attention except confirm the order. Klaviyo’s transactional emails can include product recommendations, loyalty program mentions, review requests, and referral prompts. The difference in revenue per email sent is substantial.

Enable browse abandonment tracking

Browse abandonment requires the Klaviyo JavaScript snippet to be correctly installed on your Shopify store and configured to identify visitors. The snippet must fire before the visitor leaves the page. Without correct installation, you cannot trigger browse abandonment flows — which are among the highest-converting flows available in Klaviyo.

Sync historical order data

When you first connect Klaviyo to Shopify, sync historical order data. It allows you to build segments based on past purchase behavior immediately rather than waiting months for data to accumulate. This is a one-time step many brands skip and then wish they had done from the beginning.

The five settings to verify

• Active onsite tracking is enabled in your Klaviyo Shopify integration settings
• Transactional emails are being sent through Klaviyo, not Shopify defaults
• Historical order data has been synced
• The Klaviyo checkout integration is active — this captures email at checkout for Klaviyo identification, expanding who you can target with flows
• Product catalog sync is enabled and your products appear correctly in Klaviyo’s product blocks

Once your integration is live, run a free FlowScore audit at klaviyoscore.com to confirm everything is tracking correctly and see what your email marketing system is missing.

The segments you can build from day one

Once historical order data is synced, build these immediately: all-time purchasers with more than two orders (your VIPs), all-time purchasers with exactly one order (at-risk of never returning), and purchasers with total spend above your top 20 percent threshold. These segments let you identify your most valuable customers, your most at-risk ones, and your untapped high-value opportunities from the first day you connect the integration correctly.
