The problem

Every “Sold Out” badge is a customer walking away.

Without a way to capture demand, you lose the sale — and the insight. DemandLoop turns stock-outs into a growth channel.

DemandLoop is a back in stock notification app for Shopify that helps you capture waitlists on sold-out products and automatically notify shoppers when inventory returns via email and web push.

Capture demand

A one-click Notify Me button converts “sold out” visitors into subscribers — no account required.

Notify instantly

When stock returns, alerts fire automatically via email and web push — right to the customer’s device.

Attribute revenue

See exactly how much revenue each restock notification generates — down to the order level.

Features

Everything you need to recover lost sales

From the moment a product sells out to the moment a customer completes a purchase — DemandLoop covers the entire loop.

Back in Stock Alerts (Email + Web Push)

Variant-level Notify Me buttons with automatic alerts when inventory returns. Works with any Shopify theme.

Waitlist Capture on Sold-Out Products

Add a Notify Me button to any sold-out product page. Capture email and web push subscribers automatically — one click, no account needed.

Smart Automation (Cooldowns, Batching, Reminders)

Fair Queue batching, reminder sequences, cooldown rules — set it once, let it run on autopilot.

Revenue Attribution & Analytics

Track attributed orders, CTR, conversion rates, and top demanded products — all in a real-time dashboard.

Deliverability Tools (Custom Domain, SPF/DKIM)

Custom sending domains, SPF/DKIM authentication, and bounce management — so your notifications actually land in the inbox.
