- Connect to Klaviyo shows an error.
- The connection is in early access. A store cannot connect until it opens for that store. Use the web feed meanwhile: see /help/klaviyo-integration.
- The tab says Klaviyo connected, but no photos show in the email.
- Look for the Product IDs matched badge in the tab. A warning there means your Klaviyo catalog came from a different store. Product ids then do not line up. Reconnect after checking both use the same Shopify store.
- Catalog items synced is 0 or has not changed.
- Click Sync now. If it stays at 0, no product has a tagged post yet. Only products with content are synced.
- The block is in the email but nothing renders.
- That is expected for a product with no tagged content. Test with a product you know has a tagged post.
- The block errors, or the whole block disappears.
- Paste it into an HTML block, inside the loop that lists the cart or order items. Copy it again from the tab in case part was missed. Check the catalog line ends with integration="api".
