No Stupid Questions

Step 1: draft an email to yourself

Step 2: put all recipients in the BCC

Step 3: now "reply all" does jack shit

Here's my snarky take on it:

Because it's not the job of the mail client to decide what parts of the protocol should be hidden from stupid users.

The solution is if you're sending a mass email that shouldn't be replied to you use BCC. So it's really the sender's fault

Outlook does give a warning now if you're sending to a distro list

As the other commentors have said, this isn't a problem with email services, it's a problem with email users. If you put all the addresses in the "To:" or "CC:" boxes, its because you want someone to Reply All. If you want to prevent that, put all the recipients in the BCC box.

Its a good idea, but fortunately someone already solved it a good while back. Now we just need a PSA to teach people to stop cramming everyone in the wrong box.

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)

When your recipient can "reply all", that means you've exposed every recipient's email address to all recipients.
At that point, "reply all" is just a convenience, without it they could just copy-paste the email addresses manually.

If you want to suppress that, don't show everyone the email address of everyone else.
For internal mail, you can use BCC. For external, use a mailer service.

I worked for a startup that got bought by Oracle. Five whole years without a reply-all storm, but the first week we had hundreds of people reply all and it was hilarious watching the admins try and fail to convince people to stop replying all.

at my last job, someone from corporate sent out a mass email to literally everyone in the company (thousands of people) without using BCC and that chain ended up lasting for weeks before someone higher up eventually said that further reply alls will be punished lmao

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.

At my work we have something in place that prevents somebody from sending to more than 50 recipients but we control our own mail servers and know how many people are in the largest department

Basically, things like this exist but aren't necessarily intuitive to set up and defaults would require contextual knowledge

They can, and do give the option for Enterprise support but not public/personal accounts. You will need to bcc if you don't want others replying.

you think thats bad. group texts automatically send to all. It doesn't even default to just replying to the last person to send to you.

Why?

Is this from that one about that lunch thing where people ignored when told to only reply to that one guy. It gave me a bit of enjoyment this week.
