Shopify low stock alerts: how to get an email when stock runs low

Checked against the live sources below on 27 October 2026.

Choose a stock level for each product that means “reorder now”, then use a tool that watches inventory and emails you when a count drops to it. Shopify Flow can be set up for similar jobs. Low Stock Alerts & Notify Me does it without building anything, on a free plan, and sends one alert per dip.

Pick the number first

An alert is only useful if the number behind it is right. Set it too low and the email arrives after you have already sold out; too high and you stop trusting it. The usual threshold is the sales you expect while an order is on its way, plus a buffer. The threshold guide shows the arithmetic, and the reorder point calculator does it for you.

Start with the product where a late warning costs the most: usually the bestseller with one supplier and a long lead time. Get that threshold right, then work down your list. Review the numbers each quarter, because sales speed and delivery times drift.

Two ways to get the email

Build a workflow. Shopify’s help center describes Shopify Flow as a free app on the Basic, Grow, Advanced and Plus plans that reacts to events in your store with triggers, conditions and actions. Shopify’s Flow page gives inventory examples, such as hiding products when they are out of stock and reordering supplies when they are low. It is flexible, and you maintain it yourself.

Install an alert app. An app does the watching and the emailing, and you only set the number. That is the trade: less control, no building.

What a good low-stock alert does

Fires once per dip. Repeated emails train you to ignore them.
Re-arms when you restock, so the next dip alerts again.
Covers variants, because the size that sells out is rarely the whole product.
Reaches you where you work, by email, and ideally in chat.

Test it before you trust it. Pick a product with a few units, set its threshold just above the current stock, and confirm that the email arrives and does not repeat. Then restock and check that the next dip alerts again.

Where Low Stock Alerts & Notify Me fits

Per its App Store listing, the app emails you the moment any product or variant drops to your threshold, sends one alert per dip with no repeats, and re-arms when you restock. The Free plan covers low-stock alerts and the back-in-stock button. Pro adds per-product thresholds, Slack alerts and a CSV export; the listing also mentions your own systems and a daily digest. Current plan prices are on the listing.

Try it free: set one threshold and get the email when stock dips.
