How to trigger unread emails for a given period ?

Hello All,

I kindly need your help on the following. I have a mailbox that receives huge number of emails per day , I`m processing those all unread emails every one minute using a third party tool and make them read after successfull processing , my concern is that I want to receive any alerts if there are unread emails after 5 minutes for example. Because this will mean that the emails are not processing hence the scenario has stopped running.

Hopefully I`m clear enough.

Best Regards,

Haytham Fekry
