So I really haven't published anything yet about it here – I'm actually planning a launch soon (😊) BUT, we've just rebuilt Gmail Meter entirely.
Now the product is called Email Meter, and it's a complete tool for advanced email analytics. We can analyze single inboxes and also entire teams and companies.

Feedback is much appreciated and I'm also open to any discussion!
