Hi @LM0721.
Welcome to the Community! Happy to help!
While the landing page isn’t you actual store’s integration, you can definitely still add our .js script to the landing page to have Klaviyo ‘listen’ to known users activity on the page as well as publish signup forms on it!
You will need to add the following script to your landing page’s HTML before the closing </body> tag to allow the use of Klaviyo forms and tracking:
<script async type="text/javascript" src="//static.klaviyo.com/onsite/js/klaviyo.js?company_id=insertcompanyIDhere"></script>
Once this script has been added, you can either publish a Pop Up Form to display it right away or add the embed form code to your desired location to display the form. This is similar to a fellow user’s recent question as well!
Once the Javascript is installed, navigate to the form builder for your popup. Within the sign up form builder select the behaviors tab and scroll down to the Show on specific URL settings and enter the exact URL for you Unbounce landing page to ensure the popup only displays there.
Thanks for participating in the Community!
