Price drop and low stock
These alerts use items shoppers already saved. Configure each threshold around the event you want to communicate, then test with a known saved price or inventory quantity.
Configure a price-drop alert
- 1
Choose the comparison
In Alerts → Price drop, enable Send price-drop alerts. Under Minimum drop, choose Percentage (%) or Fixed amount. Enter the value in Threshold.
- 2
Understand the baseline
The baseline is the price at the time that shopper saved the item. It is not the product's compare-at price. Two shoppers who saved at different prices can qualify at different times.

Save and test a reduction
Save Alerts. Save a known variant on the storefront while its price is 100, then reduce that variant's current price. Inspect the matching entry in Alert log and the Price drop email.
| Saved price | Threshold | Current price | Qualifies before other checks? |
|---|---|---|---|
| 100 | 10% | 95 | No: the reduction is only 5%. |
| 100 | 10% | 90 | Yes: the reduction reaches 10%. |
| 80 | 10% | 90 | No: it is above this shopper's saved price. |
| 100 | Fixed amount 15 | 85 | Yes, when the saved currency matches the store currency. |
Currencies
Fixed amounts are in the store currency. Items saved with a different currency code skip that fixed-amount check. The app offers Percentage for broader coverage, but this guide does not imply currency conversion; test the Markets experience you use.
When enabled, percentage thresholds must be between 0 and 100. A zero threshold still requires the current price to be lower than the saved price. A price-drop alert for the same shopper and variant has a seven-day repeat window.
Configure low-stock reminders
- 1
Enable Low stock deliberately
Open Alerts → Low stock and check Send low-stock alerts. The feature starts disabled. Enter a positive integer in When stock falls to; the starting value is 5.
- 2
Set the reminder cap
Set Max reminders per shopper from 1 to 10. This cap applies to successful low-stock deliveries for that shopper and variant; it is not a count of emails to send on every inventory update.
- 3
Test positive low stock
Save the intended variant, ensure the shopper has an eligible email and change tracked stock to a positive quantity at or below the threshold. With a threshold of 3, quantities 3, 2 and 1 can qualify; 0 does not.
If there is no alert
| Price drop | Low stock |
|---|---|
| The item needs a saved-price baseline and a lower current price. | The app needs a known positive quantity at or below the threshold. |
| Check the threshold and seven-day repeat window. | Check the per-shopper, per-variant reminder cap. |
| A fixed-amount check skips a different saved currency. | A newly saved item may need time for inventory tracking to be linked. |
Both flows need a matching saved item and an eligible address. Multi-variant product-level saves are not safely attributable to a particular size or colour; use the product page to save a selected variant for the test.
