FAST Alerts: Back in Stock
shopify back in stock alerts
Recover lost sales with back-in-stock and price-drop emails.
The problem
A sold-out product page is a customer telling you exactly what they want, at the exact moment they want it — and most stores answer with a greyed-out button. That shopper leaves, buys elsewhere, and never learns you restocked three days later. The demand was real and measurable, and it went unrecorded.
How it works
Add the Notify Me button
The button appears automatically on out-of-stock products. Shoppers leave an email address in one tap — no account, no friction.
Demand collects itself
Every subscriber is recorded against the specific variant, so you can see which size or colour people are actually waiting for.
Restock and the emails send
When inventory returns or a price drops, subscribers are emailed automatically from your own sending address.
What you get
Back-in-stock notifications
Automatic emails the moment inventory returns, sent to everyone waiting on that exact variant.
Price-drop alerts
Let shoppers register interest at a price they would pay, then tell them when you get there.
Send from your own address
Emails come from your domain, not a third party, which protects both deliverability and the brand.
Multi-language support
Templates can be translated so international customers get alerts in their own language.
Analytics dashboard
See subscribers, sends, opens and returning visitors, so you can tell what restocking is actually worth.

Questions about FAST Alerts
Do emails come from my domain?
On paid plans you can configure your own sending address, so alerts arrive from your brand rather than a third-party domain.
What counts as a notification?
One email to one subscriber. Collecting a subscriber costs nothing; only the alert you send is counted.
Does the Notify Me button work per variant?
Yes. Subscriptions are recorded against the specific variant, so someone waiting on a medium is not emailed when the large returns.
Can I see what people are waiting for before I reorder?
That is one of the more useful side effects. The dashboard shows recorded demand per product and variant, which is real purchase intent rather than a guess.
Will it match my store's design?
The button and email templates are both customisable, so they follow your typography, colours and tone.
