Klaviyo's power multiplies when it is connected to the right tools. Every integration adds data to your customer profiles, which enables better segmentation, more personalised emails, and smarter automation. But not every integration is worth the effort. Some add genuine value; others create noise.
This guide covers the integrations that actually matter for Shopify brands, based on what we configure for clients through our Klaviyo email marketing services and Shopify development.
Why integrations matter
Klaviyo's effectiveness is directly proportional to the quality of data it has access to. The core Shopify integration provides purchase history, browsing behaviour, and customer profiles. Each additional integration adds another data layer:
- Review data lets you segment by review activity and include social proof in emails
- Loyalty data enables tier-based messaging and points balance reminders
- Subscription data powers churn prevention and reactivation flows
- Helpdesk data prevents sending promotional emails to customers with open support tickets
- Advertising data allows cross-channel audience synchronisation
Review platform integrations
Judge.me
Judge.me is the most popular review platform for Shopify and integrates natively with Klaviyo. It syncs review activity to Klaviyo profiles, allowing you to segment by review status, trigger review request flows, and include star ratings and review snippets in email templates.
Yotpo
Yotpo offers a deeper feature set including visual reviews (photos and videos), Q&A, and advanced analytics. Its Klaviyo integration syncs review data, photo reviews, and loyalty data (if using Yotpo Loyalty). Best for larger brands that need enterprise review features.
Trustpilot
Trustpilot integrates with Klaviyo at a basic level, syncing review activity. It is most useful for brands that use Trustpilot as their primary review platform and want to trigger review requests through Klaviyo flows rather than Trustpilot's native emails.
How to use review data in Klaviyo
- Trigger review request emails 7 to 14 days after delivery
- Include star ratings in abandoned cart and browse abandonment emails for social proof
- Segment customers who have left positive reviews for advocacy campaigns
- Identify customers who left negative reviews and suppress them from certain promotions
Loyalty programme integrations
LoyaltyLion
LoyaltyLion syncs points balances, tier status, and loyalty activity to Klaviyo. This enables points balance emails, tier upgrade notifications, and loyalty-exclusive campaigns. It is the most popular loyalty integration for Shopify Plus brands.
Smile.io
Smile.io offers a simpler loyalty solution with good Klaviyo integration. Points balances and referral data sync to Klaviyo profiles, enabling basic loyalty messaging within your email flows.
How to use loyalty data in Klaviyo
- Send points balance reminders to encourage redemption
- Trigger congratulations emails when customers reach a new loyalty tier
- Create VIP campaigns exclusively for top-tier loyalty members
- Use loyalty status as a conditional split in flows for personalised messaging
Subscription integrations
Recharge
Recharge is the leading subscription platform for Shopify and integrates deeply with Klaviyo. It syncs subscription status, upcoming charge dates, skipped orders, and cancellations. This data powers churn prevention flows, upcoming charge notifications, and reactivation campaigns for cancelled subscribers.
Loop Subscriptions
Loop is a newer alternative to Recharge with competitive Klaviyo integration. It syncs similar data points and is popular with brands looking for a more modern subscription management experience.
Helpdesk integrations
Gorgias
Gorgias is the most popular helpdesk for Shopify brands and integrates with Klaviyo to sync support ticket data. The key benefit: you can suppress customers with open support tickets from promotional emails, avoiding the tone-deaf experience of promoting a sale to someone who is upset about a missing order.
Zendesk
Zendesk integrates with Klaviyo at a basic level, syncing ticket status and customer satisfaction scores. Use this data to adjust messaging for customers who have had negative support experiences.
Analytics integrations
Google Analytics
Klaviyo automatically appends UTM parameters to email links, which appear in Google Analytics. This allows you to compare email performance in Klaviyo's attribution model against Google Analytics' attribution model for a more complete picture.
Snowflake / BigQuery
For advanced analytics, Klaviyo can push data to cloud data warehouses. This is useful for brands that run custom analytics, build machine learning models, or need to combine Klaviyo data with data from other sources in a unified analytics environment.
Advertising platform integrations
Meta Ads (Facebook and Instagram)
Sync Klaviyo segments to Meta as custom audiences. This enables email-based retargeting (show ads to people who opened but did not click), suppression (exclude recent purchasers from acquisition ads), and lookalike audiences based on your highest-value email segments.
Google Ads
Sync customer lists to Google Ads for Customer Match targeting. Reach your email subscribers across Google Search, YouTube, and Display when they are not in their inbox.
