Shopify Klaviyo Integration: Sync Loyalty Data in 3 Min

The Shopify Klaviyo integration gets more powerful when you feed it loyalty and subscription data. Out of the box, Klaviyo knows about purchases and browsing. It does not know a customer's loyalty tier, points balance, subscription status, or cashback wallet amount. Connecting SubZwallet to Klaviyo fills those gaps in about 3 minutes and lets you build email flows that actually reference what matters to each subscriber.

What data syncs from SubZwallet to Klaviyo

Once connected, these customer properties push to Klaviyo in real-time:

Loyalty tier (Bronze, Silver, Gold, or your custom names)
Points balance: current total and lifetime earned
Subscription status: active, paused, cancelled, or none
Subscription plan name and next renewal date
Cashback wallet balance in dollars
Last redemption date for points or cashback
Total subscription renewals completed

Every property updates automatically when customers interact with your store. No manual exports or CSV uploads.

How to connect SubZwallet to Klaviyo

In SubZwallet, go to Settings > Integrations.
Click Connect Klaviyo and paste your Klaviyo API key.
Select which properties to sync (sync all of them for maximum flexibility).
Click Save. Data starts flowing immediately.

That is the full setup. Historical data for existing customers backfills within a few hours depending on your list size.

6 email flows you can build with this data

These flows use SubZwallet properties as triggers and personalization variables inside Klaviyo. Each one targets a specific retention or engagement goal.

1. VIP tier upgrade celebration

Trigger: loyalty tier changes to Silver or Gold. Send a congratulatory email listing their new perks and better earning rate. Merchants running this flow see 12-18% click-through rates because the email is directly relevant to something the customer just achieved.

2. Points redemption nudge

Trigger: points balance passes 500 (or your chosen threshold). Show the exact balance and what they can redeem it for. Link directly to the rewards page. Unredeemed points represent wasted engagement. This flow typically converts 8-15% of recipients into redeemers.

3. Pre-renewal loyalty reminder

Trigger: 3 days before subscription renewal. Remind the customer of the upcoming charge, show how many points they will earn on this renewal, and display their cashback wallet balance. This reduces failed payments (customers update expired cards proactively) and reinforces the value of staying subscribed.

4. Win-back with loyalty data

Trigger: subscription status changes to cancelled. Day 7: "You have 340 unused points and $12.50 in your wallet." Day 14: offer 2x points if they resubscribe within 48 hours. Day 30: final offer with improved cashback rate for returning subscribers. Referencing actual balances outperforms generic "we miss you" emails by 3-4x on reactivation rate.

5. Cashback wallet reminder

Trigger: wallet balance exceeds $10 and no purchase in 14 days. Show the dollar amount and suggest products they could apply it to. The loss aversion angle works well here. Customers do not want to leave money sitting unused.

6. At-risk subscriber intervention

Trigger: subscriber has skipped 2+ deliveries. Offer to adjust frequency, swap products, or provide a one-time cashback bonus. Acting before they cancel is 3-5x more effective than running a win-back after the fact.

Best practices for the Klaviyo + SubZwallet setup

Use Klaviyo personalization tags to show actual balances: "You have {{ person|lookup:'cashback_balance' }} in your wallet" is more compelling than "You have cashback waiting."
Segment by tier. Gold customers should get VIP treatment in every email, not just loyalty-specific ones.
Set frequency caps. With loyalty, subscription, and cashback triggers all active, it is easy to over-email. Prioritize the flows with the highest revenue impact.
A/B test incentive amounts in win-back flows. Some stores find 100 bonus points works as well as 500. Start low.
