The Back in Stock automation sends customers an automated email when an out-of-stock product becomes available for online purchase. This feature uses a Seguno email inside a Shopify Flow workflow and requires adding a Back in Stock app block to product pages before activating the workflow.
Note:
The Back in Stock automation is a paid feature in Seguno.
Requirements
A Shopify 2.0 (non-legacy) theme for easy installation.
Products must be available for online sales fulfillment.
The automation must be turned on in Shopify Flow and Seguno to send emails.
Warning:
Back in Stock is not available by default in legacy Shopify themes. Please contact Seguno support for assistance if you are not using a Shopify 2.0 theme.
Step one: Add the Back in Stock app block
Seguno collects restock alert requests using a Shopify theme app block. This block appears only when the product inventory is zero and hides automatically once inventory is one or greater.
To add the app block to product pages:
Open the Shopify theme editor.
Click the Home page drop-down menu
Select Products
Select Default product
Under Product information, click Add block
Under Apps, select Back in stock form by Seguno
Note:
If you have multiple product page templates, you will need to add the Back in Stock app block to each of them.
Optional: Add a newsletter signup checkbox to the Back in stock app block:
Select the Back in stock form app block
Select Show newsletter signup
Note:
Customers who select the checkbox are marked as subscribed for marketing emails. Customers who do not select the checkbox only receive the Back in Stock notification.
Step two: Create the automation in Shopify Flow
Once the app block is set up, it is time to customize and activate the automation. The automation template includes a Seguno marketing email action. This email utilizes Seguno email templates and editor.
All templates will automatically include a dynamic section that will populate the details and image of the item that is back in stock.
To create a Back in Stock automation:
In Seguno, navigate to the Automations page.
In the Back in stock section, click Create automation.
Select Send a back in stock email by Seguno.
Click on the marketing email action and select a template.
Select a template, click Customize.
Edit the email, then click Save and Exit
Click Turn on workflow
Tip:
Seguno’s recommended template includes a dynamic product section that automatically inserts the product title, image, and link.
Exclude products from Back in stock
There may be instances where you want to avoid giving shoppers the option to register for Back in Stock notifications for a certain product. To exclude a product, add an exclusion tag. Seguno reads the tag and will not show the Back in Stock app block for the related products.
To exclude a product:
Select the Back in stock form app block in the Shopify theme editor.
Confirm or update the Product exclusion tag.
Default tag: back-in-stock-excluded
In Shopify Admin, open Products.
Select the product to exclude.
Add the exclusion tag and then Save.
Note:
Excluded products will not display the app block and cannot collect registrations.
Set an inventory threshold
The inventory threshold determines when the Back in Stock email sends. The default threshold is one available-online unit.
To update the threshold:
Navigate to the Automations page.
In the Back in Stock section, click Set threshold.
Enter the inventory threshold value.
Click Save.
Note:
Threshold changes apply to all Back in Stock automations.

View and edit Back in Stock emails in Seguno
Emails created in Shopify Flow are also visible in Seguno.
Note: Creating a Seguno email within a Shopify marketing automation will automatically activate the automation in Seguno, but the automation will only send once it is turned on in Shopify. To begin triggering the automation, turn on the automation in Shopify.
To view and edit the email in Seguno:
Navigate to the Automations page
From the Back in Stock section, select the email
Use the Automation details page to edit content or review reporting.
Note:
The automation sends only when it is turned on in Shopify Flow.
Tip: Use the liquid tag: {{ back_in_stock_product.title }} to reference the product title in your Subject Line or any rich text section.
