Hi everyone,
I think that we should have a feature in E-mail marketing that would let us track and remove more easily inactive subscribers linked to the Campaign stats .
I give you an example :
You have 1’000 subscribers to your mailing list and in 2020 you have sent 12 newsletters (one by month).
It could be great to able to take the total or partial number of the newsletters sent last year (or different time periods) and see how many same subscribers have never receive our e-mails or never open it.
So on 12 newsletter sent maybe 50 same subscribers have never received or open any of your marketing e-mails.
When you know it you can decide to remove them by selecting all or manually in the dashboard.
The idea is to keep our mailing list updated more easily and avoid inactive subscribers that cost you money and impact your opening/conversion rates. 
Hope that it makes sense !
