How to Connect Klaviyo to Squarespace
Step 1: Create a Klaviyo Account
Go to klaviyo.com and create an account. Klaviyo offers a free plan for up to 250 contacts and 500 email sends per month - enough to set up and test the integration. Select e-commerce as your business type during onboarding so Klaviyo configures the right default settings.
Step 2: Connect via Squarespace Extensions
In your Squarespace dashboard, go to Extensions and search for Klaviyo. Click Connect and authorize Klaviyo to access your Squarespace Commerce data - products, orders, customers, and site activity. Klaviyo begins syncing historical data immediately after connection.
Step 3: Add the Klaviyo Tracking Script
Klaviyo provides a JavaScript tracking snippet that monitors visitor behavior on your site - page views, product views, add-to-cart actions, and checkout steps. Add this snippet to Settings > Advanced > Code Injection > Header in Squarespace. This script powers browse abandonment flows and on-site activity tracking. For Code Injection setup, our guide to custom code injection on Squarespace covers header injection.
Step 4: Verify Data Sync
In your Klaviyo dashboard, go to Analytics > Metrics and verify that Squarespace events are flowing in - Placed Order, Ordered Product, Started Checkout, and Viewed Product should appear. Check the Profiles section to confirm customer data is syncing correctly. Allow 24 hours for historical data to fully import.
Essential Klaviyo Automation Flows for Squarespace
Abandoned Cart Recovery
The highest-ROI automation for any e-commerce store. When a customer adds items to their cart and leaves without purchasing, Klaviyo sends a series of reminder emails - typically at 1 hour, 24 hours, and 72 hours after abandonment. Include the abandoned products, images, and a direct link back to checkout. Many stores recover 5 to 15 percent of abandoned carts through this flow alone.
Post-Purchase Follow-Up
After a customer completes a purchase, send a series of emails: order confirmation (immediate), shipping update (when fulfilled), delivery follow-up (3 to 5 days after delivery), and review request (7 to 14 days after delivery). This flow builds customer loyalty, reduces support inquiries, and generates reviews that boost future sales.
Welcome Series
When a new subscriber joins your email list (through a Squarespace form, popup, or checkout), Klaviyo sends a welcome series - typically 3 to 5 emails over one to two weeks. Introduce your brand, share your best content, offer a first-purchase discount, and showcase popular products. Welcome flows consistently generate higher revenue per recipient than any other email type.
Browse Abandonment
When a visitor views products on your Squarespace store but does not add anything to cart, Klaviyo can send a follow-up email showing the products they viewed. This requires the Klaviyo tracking script to be installed (Step 3 above). Browse abandonment flows have lower conversion rates than cart abandonment but reach a much larger audience.
Win-Back Campaign
Target customers who have not purchased in 60, 90, or 120 days with a re-engagement campaign. Offer a special discount, showcase new products, or simply remind them your store exists. Win-back flows prevent customer churn and reactivate lapsed buyers. For e-commerce strategies, our guide to Squarespace e-commerce customization covers checkout and conversion optimization that supports email marketing.
Klaviyo Signup Forms on Squarespace
Klaviyo Popup Forms
Klaviyo includes a built-in popup form builder that displays signup forms on your Squarespace site. Configure the popup design, trigger (time delay, scroll depth, exit intent), and targeting (new vs. returning visitors, specific pages). The popup collects email addresses directly into your Klaviyo list without needing a separate Squarespace form.
Embedded Klaviyo Forms
Create an embedded signup form in Klaviyo and paste the embed code into a Squarespace Code Block. This places the form inline with your page content - useful for newsletter signups in blog posts, footer areas, or dedicated signup pages. Style the form in Klaviyo's form builder to match your Squarespace template's colors and fonts. For design consistency, our Squarespace design tips guide covers visual integration of third-party elements.
Klaviyo vs. Squarespace Email Campaigns vs. Mailchimp
Klaviyo excels at e-commerce automation - behavioral triggers, revenue attribution, product recommendations, and advanced segmentation based on purchase history. It is the best choice for Squarespace stores that want data-driven email marketing.
Squarespace Email Campaigns is built into the platform and handles basic newsletters and promotional emails. It is simpler but lacks automation flows, behavioral tracking, and advanced segmentation.
Mailchimp offers a middle ground - more automation than Squarespace Email Campaigns but less e-commerce depth than Klaviyo. It integrates with Squarespace through the Extensions marketplace. For Mailchimp setup, our guide to Mailchimp Squarespace integration covers the connection process.
Choose Klaviyo if e-commerce revenue from email is a priority. Choose Squarespace Email Campaigns for simple newsletters. Choose Mailchimp for a balance of features and simplicity.
Klaviyo Segmentation for Squarespace Stores
Klaviyo's segmentation engine uses Squarespace data to create targeted audience groups:
By purchase behavior: Customers who bought specific products, spent over a certain amount, or purchased in the last 30 days.
By engagement: Subscribers who opened your last three emails, clicked a link, or have not engaged in 90 days.
By browsing activity: Visitors who viewed specific product categories but did not purchase (requires the tracking script).
By customer lifecycle: First-time buyers, repeat customers, VIP customers (top 10% by revenue), and at-risk customers (previously active but declining engagement).
Send different campaigns to each segment - product recommendations to browsers, loyalty rewards to VIPs, and reactivation offers to lapsed customers. Segmented campaigns consistently outperform generic broadcasts.

Troubleshooting Klaviyo Squarespace Integration
Data Not Syncing
Verify the extension connection is active in both the Squarespace Extensions panel and Klaviyo's Integrations settings. Check that your Squarespace plan is Commerce Basic or Advanced - Business plans may not sync all commerce data. Allow 24 hours for initial historical data sync.
Tracking Script Not Working
Verify the script is in Code Injection > Header and includes your correct Klaviyo public API key. Check the browser console for JavaScript errors. Test in incognito mode since ad blockers can prevent the tracking script from loading. For script management, our guide to adding custom code to Squarespace covers Code Injection troubleshooting.
Abandoned Cart Emails Not Sending
The abandoned cart flow requires the tracking script to detect cart activity. Verify the script is installed and firing correctly. Check that the flow is active in Klaviyo's Flows section. Verify the flow's trigger is set to "Started Checkout" or "Added to Cart" and that the time delay is configured correctly.
