The back in stock form in Seguno Email Marketing lets shoppers sign up to receive a notification when an out-of-stock product becomes available again. For Shopify Online Store 2.0 (OS 2.0) themes, Seguno Email Marketing uses an App Section to simplify installation. If your store uses a legacy theme, use this guide to install the form manually using a custom Liquid snippet.
Install the back in stock form on a legacy theme
Step 1: Create the snippet
In your Shopify theme code editor, create a new snippet and name it seguno-back-in-stock.liquid.
Open the seguno-back-in-stock_snippet.txt file.
Copy the full snippet code and paste it into your new snippet file.
Note:
You can customize the form's appearance using the available attributes or by adding custom CSS in the designated input area. By default, TEST_MODE is set to true, which hides the form from shoppers while you configure and test it.
Step 2: Place the snippet on your product page
Decide where on your product page you want the form to appear. Seguno recommends placing it above the Add to cart button and near the variant selector to maximize shopper visibility.
Open the theme file that controls your product page layout. This is typically product-template.liquid, but may vary by theme; you may need to trace the product details rendering to the correct file.
Add the following tag in your chosen location:
{% render 'seguno-back-in-stock' %}Note:
Do not place the back in stock form inside another HTML form element. If the form does not appear on the product page, check whether product details are rendered from a different theme file.
Step 3: Test the form
Navigate to an out-of-stock product or variant on your storefront.
Add
?bis-test=trueto the end of the page URL and reload the page.Confirm the form appears and renders as expected.
Tip:
If the form does not load, open your browser's developer tools to identify the error. CSS errors in the snippet may prevent the form from rendering.
Step 4: Go live
Finish customizing the form's styling.
In the snippet, update the TEST_MODE attribute value from true to false.
Remove the
?bis-test=trueURL parameter and reload the product page to confirm the form behaves correctly in production.
