Hello Roland,
thanks for your interest in SmartInspect. The described scenario is possible with SmartInspect, but currently not built-in. The SmartInspect libraries currently do not have a protocol to send email.
However, you could do this yourself by registering a custom protocol which adds the email functionality and does the custom filtering for you. We have an article in our article section which explains how to implement and register custom protocols:

Using Custom Protocols with the SmartInspect Libraries
But the idea with the daily reports is indeed very interesting. I added it to the list of suggestions and feature requests. If you have any questions about the custom protocol you can also contact me directly via email (click on my name below).
