You can definitely connect Squarespace with Klaviyo using Zapier, though the options vary by flow:

• Welcome Flow → Capture Squarespace form/popup submissions and send them to a Klaviyo list.

• Post-Purchase Flow → Use the “new order” trigger in Squarespace → send event to Klaviyo.

• Abandoned Cart/Checkout/Browse/Site → These are trickier since Squarespace doesn’t expose all those events natively. You’d need either custom tracking (via Klaviyo API or Google Tag Manager) or a middleware like Make for more flexibility.

If you want to avoid coding altogether, I’d start with Zapier for signups + purchases, then layer in custom event tracking if you need the abandoned flows.

Thanks for the response Julia, are you a Klaviyo partner by any chance?

Hey ​@JonAde,

You may want to take a look at our Agency Partner Directory so you can get in contact with a partner who can build this integration for you! Additionally, if you have some developer experience, I’d recommend taking a look at our article on how to integrate with Klaviyo without a pre-built integration. Might be something you can do solo if you have the technical know-how and follow our guides!

Feel free to reach back out with any questions. More than happy to answer.

Hi ​@JonAde ,
This is definitely doable with Zapier and some custom event tracking on your Squarespace site.
You can send the right data into Klaviyo to trigger each of those flows reliably.
If you want someone to map it out and set it up end to end, I can help with that.
Let me know what stage you're at and we can go from there.

You can reach out to me on my email here
