Turn sold-out shoppers into recovered sales

Capture emails when products run out. Notify customers the moment inventory returns—automatically.

How it works

Three steps from stockout to sale

Install once, then let inventory updates and email sequences do the follow-up for you.

Notify Me When Available

Sold out

Shoppers subscribe in one click. You get the demand signal and the recovery email ready to send.

  1. 01

    Add the Notify Me widget

    Enable the theme app embed. The button appears automatically on out-of-stock product variants.

  2. 02

    Capture eager shoppers

    Customers leave their email in a branded popup. Unlimited subscribers on every plan.

  3. 03

    Notify on restock

    When inventory returns, automated emails go out with optional follow-ups until they buy.

Features

Everything you need to run back-in-stock

Built for Shopify merchants who want waitlists, restock emails, and clear attribution— without a complicated setup.

Notify Me on product pages

Show a customizable button and popup whenever a variant is unavailable—without editing theme code.

Automated restock emails

Inventory webhooks trigger notifications the moment stock returns, with delivery rules you control.

Follow-up sequences

Send confirmation plus first through fourth notifications so hot demand does not go cold.

Brandable email templates

Edit subjects, body copy, logo, and accent color. Paid plans can send from your own domain.

See waiting subscribers, top requested products, attributed orders, and recovered revenue.

Smart delivery controls

Set delays, minimum stock thresholds, notify-per-unit limits, and newest-first priority.

Why merchants choose it

Recover revenue hiding in every stockout

Sold-out pages do not have to be dead ends. Give customers a clear next step and measure what comes back.

Stop losing sold-out demand

Every stockout is a chance to collect intent. Keep shoppers warm instead of sending them to competitors.
