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.
The way to do this is to use a mailing list that only allows a limited number of people to send emails to it. You could do this automatically when someone clicked a “Prohibit Reply All” button, but such a feature is unnecessary if you use mailing lists configured that way by default.
That basically means sending the same email over and over but with one recipient per email
That isn’t what it means at all.
Yes, it is precisely what mailing lists do.
