How to view all related communication with a contact, lead, customer or supplier

It’s not like I’m asking for a feature It’s more like I’m pretty sure something is not working like intended so I would qualify it as a bug. I, therefore, asked for a confirmation that it’s a bug on the forum and posted issues on GitHub. Unfortunately without any response that makes clear if it’s a bug or that I’m doing something wrong in the setup.

I would say communication with your customers and suppliers is on the most important aspects of a business and unless the rest of the ERPNext users are using pigeons to do so I would think one or two might use emails to communicate and could, therefore, tell me how they integrate emails in their ERPNext workflow.

The question of this thread was if I Could get an overview of all communication the way I subscribed it with a custom script or that it would require more programming.
