Built for ShopifyBack in Stock

Sold out is a list
of buyers.

Every sold-out product quietly collects the shoppers who wanted it. The moment it is back they hear about it by email, SMS or WhatsApp, and the sale you were about to lose comes home.

Notify

The instant stock returns, they know.

Alert Me! watches your inventory. The moment a product is back, every waiting shopper gets a message on the channel they chose, with a link straight to the product. Nothing to press.

  • Fires automatically on restock, per product and per variant
  • Email on every plan; SMS and WhatsApp from Starter
  • One subscriber list across all three channels
  • Minimum-stock trigger so one returned unit does not fire hundreds of alerts

Control

Notify in waves, not a stampede.

Fifty alerts for three units is a bad day for everyone. The delivery policy sends in batches sized to your stock, so the shoppers you notify can actually buy, and the rest keep their place.

  • Automatic, or batched: 25 an hour, 100 a day, whatever fits
  • Pauses at zero and resumes on the next restock
  • Per-location and per-market inventory
  • Reminder alert for shoppers who did not open the first

“Installed this app for our store to handle back-in-stock notifications. The app works like a charm! What impressed me even more was their support team—they quickly jumped in as collaborators to help us fine-tune the button placement and styling so it perfectly matches our theme. Super responsive and highly recommended!”

FAQ

Back in Stock questions.

Do I need to edit my theme code?

No. Alert Me! installs through the Shopify theme app embed. Switch it on in the theme editor and the Notify me button appears on sold-out products by itself. No Liquid edits, no developer.

Where does the button show?

On the product page by default. You can also show it on collection pages and the home page, and place it exactly where you want with the app block.

Which channels can alerts go out on?

Email on every plan. SMS and WhatsApp from Starter. On Standard you can send WhatsApp from your own verified number with your own approved templates.

What happens when only one unit comes back?

Set a minimum inventory trigger so a single returned unit does not fire hundreds of alerts. You can also batch alerts to avoid overselling.

Can I import an existing waitlist?

Yes. CSV import and export are included on Standard, so a list from another app comes with you.

Does it work with Klaviyo?

Yes. From Starter, subscribers and restock events sync to Klaviyo so you can trigger flows and build segments.

Stop losing the sale at “Sold out”.

Install free. The button is live on your theme in two steps, no developer needed.
