Sold out today.
Sold again tomorrow.
Sold out isn’t a lost sale — it’s a waiting list you haven’t built yet. Tag everyone who asked, and when the restock lands, one campaign turns the wait into a queue at checkout.

The play
How it works in BIP
Tag the demand as it happens
A customer asks about the sold-out sneaker — on WhatsApp, at the counter, in a DM. Tag them "waiting-neon-drop" via the panel or the API. Ten seconds, done.
Watch the list grow
The tag becomes a live waiting list. The segment "tags include waiting-neon-drop" shows its count in real time — you know exactly how deep the demand runs before you reorder.
Announce to exactly who asked
Restock arrives Tuesday. A one-time campaign goes to the tag — "It’s back, and you asked first" — with their name and a direct link. Then a second step removes the tag so nobody gets next season’s alert by accident.
84 people asked. 84 people heard first.
A streetwear shop sells out of a limited drop in four hours. Over the next two weeks, 84 people ask about it — each gets tagged. When the reorder lands, the campaign goes out at 10 am: 84 sends, personalized, to people who literally asked to be messaged. No ad budget, no discount needed, and the second drop moves before lunch.

Questions about this play
Can’t find the answer you’re looking for? Talk to our team — a human replies.
How do I tag who asked?
Both work. Tag manually from the lead profile, in bulk from a list, or programmatically via the leads API when someone clicks "notify me" on your site.
How do I reset the list after the restock?
Send a campaign that includes a remove-tag step via the API, or clear it in bulk from the panel after the blast — so the list always means "still waiting".
What does a waiting list cost?
Storing the waiting list costs nothing. You pay for the announcement sends — 84 people waiting means the whole play costs 84 sends.
