Do-not-email cards

I just got started with newsletters and this is clearly a feature that I’d like to have and I came across this post. Any news on this one @galligan @badrihippo?

There is a related idea (Excerpt only newsletter and/or respect the public view content divider) which got closed after being referred to Premium previews for email newsletters which doesn’t satisfied my use case. I run a hobby site, have only free members and don’t intend to use premium (paid for) subscriptions. I remember that Ghost made a clear shift to focus solely on people wanted to make money out of their blog ://
