I’m having trouble setting up a basic Omnisend review integration

Before resorting to adding custom Liquid code directly into the theme, I’m hoping to find a simpler workaround - something that would be easy for my client to enable or disable as needed.

However, I’m getting the following error:

“product-reviews” not added. Liquid templates don’t support sections and blocks.

Has anyone found a clean way to display product reviews (or even just star ratings) in Omnisend emails without relying on {% section %} tags, which obviously aren’t supported in this context?

Hi there, and thanks so much for sharing your challenges — it’s incredibly helpful for the broader community, and we’re glad to have the chance to join the conversation.

To clarify, the correct way to display product reviews is through a Custom Liquid block. This block allows for dynamic content rendering, including reviews, but it needs to be handled independently of Shopify’s section-based structure. If your theme doesn’t support a custom block out of the box, you would indeed need to create a custom one manually, just as you mentioned.

At this point, there isn’t an alternative workaround that would allow for toggling review display via a simple enable/disable toggle without modifying the theme. That said, we do believe the current setup, while requiring some initial effort, should remain manageable both for implementation and ongoing moderation.

If you need a hand with the initial setup, or if any questions pop up along the way, feel free to reach out to our support team via in-app chat or email us at support@omnisend.com — we’ve got your back!
