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.
Just don’t use it for mass mailing external addresses. That’ll get you on a blacklist faster than you’d think.
What do you mean by this?
Putting a bunch of recipients in bcc to send out mass mail is what spammers do.
So if you also do this, you’ll look like a spammer.
This may lead to your emails getting rejected by various mail servers in the future.
