AI for scanning, categorizing, and logging eamils?

I'm looking for a potential AI solution for something I'm trying to accomplish with my business. The large majority of customer communications are through employee emails and I'm hoping a solution exists that may be able to track specific situations and send notices to me if those scenarios occur. For example, customers checking up on delivery dates or adding items to orders last minute. To take it even a step fruther, if it could notice when an employee is responding rudely to a customer (or vice versa). Our number of employees and volume of emails is too high to track through our normal system. I am not an AI expert so if anyone has suggestions or can point me in the right direction, I would appreciate it.
