Hi Lanka,

I do not recall a standard functionality that can trigger a mail to send an email for item expiration. But there are couple of workarounds that you can try to achieve this requirement.

1. Create a custom report to get the expired items with a date parameter as input and then schedule that report to generate and send as a e mail.
2. Create a custom API to generate the expired items list and then return the count of records as a output. Then using a IF condition you can trigger the email sending by using Command_SYS.Mail() function if the count is greater than Zero with the list of expired item list.

Hope this will help.

Regards,
