Hi ​@Teagan,

Have you checked out the article below? It explains how to embed a form on your site, and has instructions for sites that are not natively synced to Klaiviyo. I’m not 100% sure, but I think a pop up form works in a similar way.

Hope this helps, let me know if you have more questions!

• Yes, this is a known behavior in Magento where system URLs get passed to Klaviyo instead of the proper SEO-friendly URLs.

• Magento by default generates both system paths and rewritten SEO URLs, but sometimes integrations only pull the system path.

• The support is partly correct—many Magento users do face this, especially when using email marketing tools like Klaviyo.

• The SEO issue here is that system URLs (e.g., /catalog/category/id/6) are not optimized for search engines or user experience.

• Manually editing the URL in the Klaviyo email template is one workaround, but it’s not scalable for large catalogs.

• A common solution is customizing the integration so Klaviyo pulls the URL rewrite table (which stores Tow URLs).

• You can check Magento’s URL Rewrite Management in admin to confirm the correct SEO-optimized links exist.

• Developers often use Magento’s getProductUrl() function instead of system paths to ensure SEO links are retrieved.

• This matters because emails with poor URLs can reduce click-through rates and negatively impact SEO performance when shared.

• If you’re serious about SEO optimization, ensuring that all marketing channels use clean, human-readable URLs is essential.

• Some Magento-Klaviyo users add middleware or extensions to automatically replace system URLs with SEO-friendly product links.

• In short: yes, others have encountered this, but with the right SEO customization, you can make Klaviyo pull the proper rewritten URLs instead of editing them manually.
