1. What is Back in stock alert?
Back in stock alert is a block that lets customers sign up to be notified when an out-of-stock product becomes available again, instead of leaving your store empty-handed. When a customer submits the form, you (the store owner) receive an email with their contact details and which variant they were interested in.
⚠️ Important: This block only notifies you - it does not automatically email the customer once the product is back in stock. You'll need to reach out to them manually, or connect an email marketing tool to collect these sign-ups and send that "it's back!" notification automatically once you restock.

5. Common Use Cases
🤔 How to set up the Back in stock alert block?
STEP 1: Add the block
Add Back in stock alert directly on the Product information or Quick view section, or inside the Product details block on Product three columns / Product showcase.
STEP 2: Fill in the form content
- Heading - optional title for the sign-up form.
- Text - supporting message. Default: "Sign up to be the first to know when it's back in stock."
- Button label - default: "Send".
- Success message - shown after a customer submits the form. Default: "Thank you for signing up. We'll get back to you as soon as possible."
STEP 3: Choose when it appears
Toggle "Only show when product is unavailable" on if you want the block to appear only when a product is out of stock (default OFF, meaning it shows regardless of stock status).
STEP 4: Click "Save" when done.
🤔 How does the notification flow actually work?
It's a one-way flow, and it's worth understanding before you rely on it:
- When a customer submits the form, you receive an email containing their contact details and the specific variant they signed up for.
- The theme does not automatically email the customer when that product is restocked. That step is entirely manual on your end.
💡 Tip: If you'd rather not track and send these emails one by one, consider connecting an email marketing tool. Most let you collect sign-ups from a form like this one into a list, then send an automated "back in stock" email to everyone on it the moment you update the product's inventory - no manual follow-up needed.
