How to create a report on how many contacts were emailed by each connected inbox in HubSpot

Hi everyone, just wanted to ask if the report I have in mind is possible to create?

We want to create a report that shows the count of contacts emailed by every connected email inbox to our company’s HubSpot CRM.
in the screenshot below is the setting of my co-worker. He has 3 work emails connected, and we need to track how many emails were sent out of email 1, email #2, email #3 per month.

Hi @mdocute123, I hope that you are well!
Thanks for asking the HubSpot Community!
Let’s invite our top Experts to this discussion: Hi @karstenkoehler, @GRajput and @Josh do you have ideas to achieve this specific use case to help @mdocute123, please?
Have a lovely day and thanks so much!
