How Back in Stock Works

Restock Alerts handles the full process of collecting customer interest and sending restock emails — so you don't have to do it manually.

The Customer Journey

• A customer visits a product page and finds their preferred size or variant is sold out.
• They click "Notify me when available" and enter their email address.
• They receive a quick confirmation email to verify their signup.
• Their request is saved in your Alert Requests list inside the app.

When a Product Restocks

• When you update inventory in Shopify and a variant goes from out of stock to in stock, the app detects the change.
• All customers who signed up for that variant get an email letting them know it's available again.
• The email includes a direct link back to the product so they can buy straight away.
• If you've set up an Alert Offer, a discount code is included in the email to give customers an extra nudge to purchase.

Who the Email Comes From

• No setup is needed. Alert emails send from our authenticated domain with your store's name as the sender, and replies go to your store's contact email.
• To fully white-label the From line, open Settings > Emails and verify your own address. You confirm the inbox with a link we send, and add three DNS records so the emails authenticate from your domain.
• Until both checks pass, emails keep sending from our domain so nothing is delayed.

After the Notification

• Once a customer is notified, their request is marked as fulfilled.
• You can see who was notified, whether they opened the email, and whether they clicked through — all in the Deliveries section.
• If a customer no longer wants to be notified, they can unsubscribe at any time using the link in the email.
