1. The Integration Reality in 2026

Critical Starting Point: No Native Integration

As of 2026, Klaviyo Squarespace Integration, do not have a native, built-in integration. This means you cannot simply toggle a switch to connect the two platforms. All integrations require third-party tools, custom code, or manual workarounds.

What This Means for You:

• E-commerce events (add to cart, purchases) require custom tracking
• Form submissions need middleware to sync automatically
• You’ll need to budget for third-party connector tools
• Implementation requires technical setup, but no-code options exist

Why It Still Works: Despite the lack of native integration, businesses successfully use Klaviyo with Squarespace by leveraging automation platforms and Klaviyo’s flexible API, Klaviyo Squarespace Integration.

2. Integration Methods: Three Approaches for 2026

Methods of Klaviyo Squarespace Integration;

Method 1: No-Code Automation Platforms (Recommended)

Best For: Small to mid-sized businesses, marketers without developers

Option A: Zapier (Most Popular)

Zapier offers pre-built connectors to sync Squarespace Forms with Klaviyo automatically.

Setup Steps:

1. Create a Zapier account
2. Connect Squarespace as the Trigger (“New Form Submission”)
3. Connect Klaviyo as the Action (“Create Subscriber”)
4. Map form fields (email, first name) to Klaviyo profile properties
5. Test and activate the Zap

Popular Zapier Workflows:

• New Squarespace form submission → Add to Klaviyo list
• New Squarespace order → Create Klaviyo event for segmentation
• New Squarespace customer → Create/update Klaviyo profile

Pros: 5-minute setup, 7,000+ app ecosystem, reliable Cons: Cost scales with volume, limited e-commerce event tracking

Pricing: Starts at $19.99/month; scales based on task volume

Option B: Make.com (Advanced Automation)

Make provides visual workflow builder for complex multi-step integrations.

Advanced Capabilities:

• Check if contact exists in Klaviyo before creating
• Add conditional logic (e.g., tag VIPs based on order value)
• Sync to multiple platforms simultaneously (Klaviyo + Slack + Google Sheets)

Pros: More powerful than Zapier, better value at scale Cons: Steeper learning curve

Option C: Integrately / Latenode

One-click automation with pre-built templates.

Integrately Example: “Automatically update customer tags in Klaviyo based on new purchases made on your Squarespace site”

Latenode Advantage: Combines no-code simplicity with advanced customization options

Method 2: Klaviyo API Integration (E-commerce Tracking)

Best For: Businesses needing full e-commerce event tracking (abandoned cart, add to cart, purchases)

The Challenge: Abandoned Cart Tracking

A major limitation of Squarespace-Klaviyo integration is abandoned cart functionality. As one user noted: “Does anyone know how to integrate Squarespace with Klaviyo so that I can create an abandon cart trigger?”. This requires custom JavaScript implementation.

Step-by-Step API Setup :

Step 1: Get Klaviyo API Credentials

• Log into Klaviyo → Settings → API Keys
• Create a new Private API Key (for server-side calls)
• Create a Public API Key (for client-side tracking)

Step 2: Install Klaviyo Tracking Code in Squarespace

1. In Squarespace, go to Settings → Advanced → Code Injection
2. Add Klaviyo’s standard tracking script in the Header section:

HTML

Preview

<script>
  var _learnq = _learnq || [];
  _learnq.push(['account', 'YOUR_PUBLIC_API_KEY']);
  (function () {
    var b = document.createElement('script'); b.type = 'text/javascript'; b.async = true;
    b.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'a.klaviyo.com/media/js/analytics/analytics.js';
    var a = document.getElementsByTagName('script')[0]; a.parentNode.insertBefore(b, a);
  })();
</script>

Step 3: Track E-commerce Events via JavaScript Add custom code to track key events:

Track Purchase:

JavaScript

// In Squarespace's Order Confirmation Page Code Injection
<script>
  _learnq.push(['track', 'Placed Order', {
    '$value': {{ order.subtotal }},
    '$event_id': '{{ order.orderNumber }}',
    'ItemNames': [{{ order.items|json }}],
    'Categories': [{{ order.categories|json }}]
  }]);
</script>

Track Add to Cart (requires developer):

JavaScript

// Custom JavaScript on product pages
document.querySelector('.sqs-add-to-cart-button').addEventListener('click', function() {
  _learnq.push(['track', 'Added to Cart', {
    '$value': {{ product.price }},
    'ProductName': '{{ product.title }}'
  }]);
});

Track Active on Site (automatic with Klaviyo script)

Pros: Full e-commerce functionality, real-time data Cons: Requires JavaScript knowledge, ongoing maintenance

---

Method 3: Manual Form Embedding

Best For: Simple email capture, no budget for automation tools

Embed Klaviyo Forms in Squarespace :

Step 1: Create Form in Klaviyo

• In Klaviyo, go to Sign-up Forms → Create Form
• Design your form using Klaviyo’s drag-and-drop builder
• Configure form fields and success messages
• Set the form to appear on specific URLs or use “embed” option

Step 2: Get Embed Code

• In Klaviyo form editor, click Publish
• Select “Embed” tab
• Copy the provided HTML/JavaScript code

Step 3: Add to Squarespace

• In Squarespace, edit the page where you want the form
• Add a Code Block (not a Form Block)
• Paste the Klaviyo embed code
• Save and test the form submission

Step 4: Style the Form

• Use custom CSS in Squarespace to match your brand
• Klaviyo forms inherit some Squarespace styling but may need adjustments
• Test on mobile devices

Pros: Free, Klaviyo handles all form logic Cons: Manual data sync, no automation, limited styling control

AI-Powered Segmentation

Klaviyo’s AI will analyze Squarespace purchase patterns to automatically suggest high-value segments (e.g., “Likely to churn,” “High LTV potential”).

Server-Side Tracking Evolution

With increasing ad blocker usage, server-side tracking for Squarespace e-commerce events will become standard. Klaviyo’s API-based event tracking bypasses browser restrictions and improves data accuracy.

Composable Commerce Architecture

2026 trend: Use integration platforms as “composable middleware” that can swap Squarespace for Shopify or Klaviyo for another ESP without rebuilding automations.

RCS & WhatsApp Integration

Klaviyo now supports RCS (Rich Communication Services) and WhatsApp messaging. Integrate Squarespace events to trigger multi-channel campaigns: email for browse abandonment, SMS for cart abandonment, WhatsApp for order confirmations.

Zero-Party Data Collection

Use Squarespace forms to collect zero-party data (preferences, intentions) and sync to Klaviyo custom properties for hyper-personalization without violating privacy regulations.
