Would like to update you that Smart Manager internally does use WordPress and WooCommerce functions itself for updating the products, so if the ‘WC Product Stock Alert’ is using correct hooks the email should trigger.
However, as you are facing an issue, could you please try to create a test product using ‘WooCommerce > Products’ and then try to reproduce the Smart Manager plugin issue using the same and do let me know your views.
Also, to find the exact cause of the issue, here’s something that will help:
- Install a free theme like Twenty Twenty or Storefront but do not activate/switch your current theme
- Install the free plugin Health Check & Troubleshooting
on your site – this plugin is developed by the www.remarpro.com team and is pretty good at diagnosing problems in such situations.
- Once the health check plugin is installed, keep only WooCommerce, WC Product Stock Alert and Smart Manager for WooCommerce plugins active for the admin side and try to reproduce the issue you reported. Make sure to do this only for the admin side – that way visitors to your site won’t be affected.
- Here’s a nice article that explains this process.
- If the issue does not occur, it means the problem is with some other plugin. You may try activating/deactivating a combination of plugins to figure out exactly what causes the problem and then let us know your views simply in a comment here
