As soon as Swym detects that a sold-out product is back in stock, Swym triggers an email to all the users who have subscribed to the Back in Stock Product Alerts for the respective product and yet to receive an email. The default minimum stock limit to trigger the alert is 1 for all products in your store.
You can, however, update this minimum stock limit to your preferred value, eg: 5. Setting this ensures, Swym triggers an In Stock Alert email only when the stock level for the particular product goes above the minimum stock limit
Please send an email to email@example.com with your desired minimum stock.
