You could not do it with any native reports or configuration. You might be able to send emails to specific email address of users but for that you have to prepare reports your self by custom development.
As you would know salesforce works on User Licenses so Inactive Users are not supposed to have access to any features ? So for example if some one purchase 10 User Licenses then only 10 active users could maximum be able to utilize the features.
I hope above explanation help you.
