@twisted1919 Have you tested this one? We finished up setup but unfortunately, it can only work with one unsubscribe domain, do you know a workaround that would allow us to add more than one unsubscribe domains?
I've asked Gerd plugin creator but it might take a while to reply so I thought I'd ask you too.
@Baramon - I don't know how the above plugin works, but i do know mailwizz adds the proper List-unsubscribe header with proper info.
It's just gmail will show it only if you have a good reputation.
