I am also having the same issue… for a few of our client accounts.
Topic summary
Main issue: Users design Shopify notification emails (order confirmation, abandoned checkout) in Klaviyo, export the HTML, and paste it into Shopify’s notification editor, but the preview does not work.
Scope: Multiple users report the same problem across different stores and client accounts.
Technical context: Klaviyo is an email marketing platform; Shopify notifications are transactional emails sent by Shopify. Users are attempting to replace default Shopify templates with custom Klaviyo HTML.
Evidence: A screenshot was shared to illustrate the preview failure; the image is central to understanding the issue.
Support actions: A community helper offered assistance and requested store URLs to investigate the problem directly.
Outcome/decisions: No fix or concrete solution has been provided yet. The immediate action item is for affected users to share their store URLs for diagnosis.
Status: Unresolved and ongoing. Key unanswered question: why Shopify’s preview fails with Klaviyo-exported templates and what steps are needed to make the templates preview correctly.
