Why not just have an easy button that you can click saying Do Not Allow Reply All?
I know that there are some ways you can limit reply-all availability, like in the URL linked here. But there’s a note: If recipients open this email in other mail applications except Microsoft Outlook, such as opening on web page via web mailbox, they can reply all this email.
I’m semi-tech savvy but I’m no programmer. It feels like it should be easy to do, so either I’m totally wrong or email services are really missing out on a great thing they could do.
My wife and I were doing big renovations on our home and were dealing with lots of contractors. I would email them and include my wife’s email. Yet every contractor failed to press reply all when responding so my wife was constantly left out of the loop
It turns out people just don’t care to think about or understand basic technology.
This stuff really needs to be taught in school (like how we used to have typing and business communication classes)
