The world of e-commerce moves fast, and if you aren’t connecting with your customers where they hang out—their inboxes and phones—you’re leaving money on the table. For many growing brands, the biggest hurdle isn’t the marketing strategy itself, but the technical setup. If you’ve been wondering how to add Klaviyo to Shopify to streamline your sales, you’ve come to the right place. At Shopify Store Manager, we know that a seamless integration is the foundation of every high-converting email and SMS campaign.
Why Integrate Klaviyo with Your Shopify Store?
Before we dive into the “how,” let’s talk about the “why.” Klaviyo isn’t just an email tool; it’s a data powerhouse. Unlike generic platforms, Klaviyo was built specifically for e-commerce. By learning how to add Klaviyo to Shopify, you unlock the ability to:
-
Sync Real-Time Data: Automatically track what customers buy, what they look at, and when they abandon their carts.
-
Automate Revenue: Set up “Flows” (like Welcome Series or Abandoned Cart reminders) that run in the background 24/7.
-
Personalize at Scale: Use Shopify’s data to send a 10% discount to a first-time browser or a VIP reward to your top spenders.
-
Unified Marketing: Manage both your email and SMS strategy from a single dashboard for a consistent brand voice.

Ready to level up? Follow these simple steps to get your integration running smoothly.
Step 1: Install the Klaviyo App
The easiest way to start is through the official marketplace.
-
Log in to your Shopify admin panel.
-
Navigate to the Shopify App Store and search for “Klaviyo.”
-
Click Install and follow the prompts to authorize the app.
-
You will be redirected to Klaviyo to either log in to an existing account or create a new one.
Step 2: Connect the Integration
Once the app is installed, you need to finalize the “handshake” between the two platforms.
-
In your Klaviyo dashboard, go to the Integrations tab.
-
Select Shopify from the list of enabled integrations.
-
Ensure your store URL is correct (e.g.,
your-store.myshopify.com). -
Check the box that says “Automatically add Klaviyo onsite JavaScript”—this is crucial for tracking website activity!
Step 3: Enable Onsite Tracking and App Embeds
To make sure Klaviyo “sees” what your visitors are doing, you must enable the App Embed within Shopify.
-
Go to your Shopify Admin > Online Store > Themes.
-
Click Customize on your active theme.
-
On the left-hand sidebar, click the App Embeds icon (it looks like a small square with a blue dot).
-
Toggle the Klaviyo switch to ON and hit Save.
Step 4: Sync Your Subscribers
Don’t forget to make sure your checkout stays in sync!
-
In Klaviyo’s Shopify integration settings, find the section for Subscriber Sync.
-
Select the specific list (usually your “Main Newsletter” list) where you want Shopify subscribers to go when they check the “Accepts Marketing” box at checkout.
Optimizing for SMS Marketing Success
One of the biggest perks of knowing how to add Klaviyo to Shopify is the built-in SMS functionality. In 2026, SMS has seen a massive surge, often boasting open rates as high as 98%.
Setting Up SMS Consent
To stay compliant, you must collect explicit consent for text marketing.
-
Update Your Checkout: In Shopify Settings > Checkout, ensure “SMS marketing” is enabled.
-
Map the Data: In Klaviyo, go to the SMS settings and ensure your “SMS Subscribers” list is mapped to collect these phone numbers.
-
Create a Mobile-First Pop-up: Use Klaviyo’s form builder to create a “Teaser” or “Spin-to-Win” pop-up specifically for mobile users to capture phone numbers.
Essential “Flows” to Launch Immediately
Once you’ve mastered how to add Klaviyo to Shopify, don’t just sit there—automate! Here are the top three flows every store needs:
| Flow Name | Trigger | Goal |
| Welcome Series | Someone signs up for your list | Introduce the brand and offer a first-purchase discount. |
| Abandoned Cart | Someone adds an item to the cart but doesn’t buy | Remind them what they’re missing and recover the sale. |
| Browse Abandonment | Someone views a product but doesn’t add to cart | Show them the product again with social proof (reviews). |
