Restock Notification Not Sending – What to Check

If customers are not receiving restock notifications, here are a few things to verify:

Check General Settings

• Go to WooCommerce > Stock Notifier > General Settings.
• Ensure “Enable Notifier” is checked.
• Ensure “Send Notification on Product Update” is enabled to trigger the notification when product stock is updated.

Email Settings

• Go to the Email Settings tab.
• Ensure both Requesting Stock Email and Back in Stock Email templates are configured correctly.
• Make sure you haven’t disabled email sending in WooCommerce > Settings > Emails.

Product Status

• Ensure the product’s stock status has changed from “Out of stock” to “In stock”.
• The stock quantity should be above zero.

Other Checks

• Test with a known email to see if the email is landing in spam/junk.
• Ensure WordPress is able to send emails by testing with another plugin or contact form.
