WhatsApp back-in-stock alert templates
Back-in-stock alerts have the highest CTR of any e-commerce WhatsApp template — 40-55% — because the customer self-identified intent by joining the waitlist. They're the easiest revenue you can recover without acquisition spend.
The flow has two halves: an out-of-stock product page that captures WhatsApp opt-in, and a templated alert when inventory replenishes. These templates handle the alert side. Pair them with a low-friction opt-in widget on your product pages.
When to use
Within 1 hour of stock replenishment. Don't batch overnight — early-bird waitlist signups will check directly and buy before your batch fires.
Approval tips
- • MARKETING category — promotional intent.
- • Avoid words like 'last chance', 'final', 'hurry now' — flagged.
Best practices
- Limit alerts per restock — first 100-200 waitlisters only. Otherwise you sell out again in minutes and disappoint the rest.
- Include current stock count for urgency: 'Only 23 left'.
- If item restocked in limited sizes/colors, specify which.
- After 48h, the waitlist gets stale. Refresh or expire entries beyond that.

FAQs
How do I collect waitlist signups?
Add a 'Notify me on WhatsApp' button on out-of-stock product pages. Most BSPs ship a JS widget for this.
What if only partial stock arrives?
Notify the first N waitlisters where N = stock_available, not the full list.
Should I include the price in the alert?
Optional. Helps if price changed since signup. Otherwise the product page handles it.
Can I send back-in-stock to non-waitlist customers?
Technically yes (with marketing opt-in), but conversion drops 80%. Stick to waitlist.
What's the optimal time-of-day?
10am-1pm local time. Avoid weekends — lower urgency response.
Does Meta allow scarcity language?
Yes — 'only X left', 'limited stock' are fine. Avoid 'last chance' or 'final hours'.
