01
Analyze & Prepare
We start by looking at your current Shopify setup and your Klaviyo account. This includes older migrations, the integration settings, and how your email and SMS subscribers are moving between the two platforms. We check the sync, look for broken links or old tags, and clean up what needs attention. The goal is to have a clear baseline before we integrate anything new.

Then we connect Klaviyo to Shopify and set up the pieces that make the sync run smoothly. This covers the app embed, event tracking, list mapping, and opt-in points. We make sure your subscribers are moving correctly, email and SMS forms are linked, and the data flow works without errors. We also prepare the key email and SMS flows so your lifecycle messages can start working right away.

Optimize & Scale
Once the integration is stable, we create advanced segmentation in Klaviyo, build new flows, improve your email templates, and fine-tune campaign structures. As data continues to sync from Shopify, we strengthen your ongoing marketing management and build new marketing strategies that use Klaviyo's most powerful features. This stage turns the integration into a long-term revenue channel.

FAQ
What is a Klaviyo Shopify Integration?
It is the connection between your Shopify store and Klaviyo. Once the two are linked, your customer data, orders, email subscribers, and SMS subscribers move into Klaviyo in a clean and steady way.
How do I integrate Klaviyo with Shopify?
First, you need to install the Klaviyo app. Then you connect it to your Shopify store and set the basic options inside Klaviyo. After that, you bring in your Shopify data and check that every email and SMS signup point sends to the right place. A23 takes care of the whole setup if you want it done for you.
Do you help with Klaviyo email flows?
Yes. As part of the integration and ongoing retention work, we build the main lifecycle flows — welcome, browse, abandoned checkout, post-purchase, winback, and other core flows your store needs.
Can you fix a broken Shopify integration?
Yes. We repair old or incomplete Klaviyo setups, fix sync issues, clean profiles, correct Shopify tags, and make sure the data starts moving the way it should.
Do you support SMS?
Yes. A23 handles email and SMS marketing from setup to migration to campaigns and automation.
