**Your software**  
My Mautic version is: 3.1  
My PHP version is: 7.2  
My Database type and version is: MySQL 8.x

**Your problem**  
My problem is:  
Is there any way to find out my unused or idle contacts easily without going through database and making complex queries to find out events and timeline of contact ?  
I have 35K+ contacts, which I imported from an old system. But most of them are just there, but 10% of these are used in various campaigns, any way to find out if they’re unused, in order to clean up.

Thanks!
