Hi,

Odoo can generate email alerts when product quantities reach their minimum stock levels. The simplest approach is to use Reordering Rules, where you set minimum and maximum quantities for products. While these typically trigger automatic replenishment, you can extend them with an automated action to send email alerts instead.

Alternatively, you can create an Automated Action directly on the product or stock model to check when the available quantity falls below the minimum and automatically send an email notification using a predefined template. For more advanced control, a scheduled cron job can be set up to run daily and send a summary email listing all products that are below their minimum stock levels.
