Back in Stock AlertsCore
Restock alerts that sell out again
A “Notify me” button on every sold-out variant. When stock returns, everyone waiting hears within 60 seconds.
Every plan.
The moment
This is Pit’s moment: the size they wanted is gone, and a promise that someone will shout is all that keeps them.
What Back in Stock Alerts does
Variant-level signups
Shoppers pick the exact size and colour they want. Unlimited signups on every plan.
Restock in 60 seconds
Inventory webhooks plus a backup scan mean nobody waits for a stale alert.
Staggered sends
Only 10 back? Send in waves, so you never promise more than you have.
Minimum stock threshold
Wait until at least X units arrive, per location and per market.
How it works
Step 1: The shopper picks the variant and taps ‘Tell me when it’s back’.
Step 2: Stock lands. WaitCherry builds the campaign in seconds: who, channel, wave.
Step 3: Alerts go out once per person, plus one reminder while stock lasts.

Back in Stock Alerts FAQ
What counts as a notification?
One notification is one restock, pre-order or price message sent to one subscriber. Web push and confirmation emails are not counted.
What happens when I hit my email limit?
On monthly plans with overage on, sending continues at $1 per 250 extra notifications up to your cap. Otherwise messages wait in a queue and go out after you upgrade or the period resets. Signups never stop.
Can shoppers sign up from collection pages?
Yes. You can show a compact notify button or badge on collection cards and the home page.
