Superadmin users see a Send test email button inside the Stock alert window (on the Retail Menu page and on Stock Management). It immediately sends the alert email for that meal and location - using the location's current stock and configured threshold - to the location's stock alert recipients or the default email, and confirms with Test email sent successfully. Other admins do not see the button (Superadmin access required). The email is also a good way to check that Select employees to receive stock alerts on the location is filled in.
