There is no way to leave email conversations if someone accidentally clicks the "Reply All" button. What you can do is put the conversation on mute to disable notifications. Here's how to disable chats on your iPhone, iPad or Mac using the Mail app.
How to disable email threads on iPhone and iPad
To disable a thread on an iPhone or iPad, you need to run iOS 13 or iPadOS 13 and higher.
There are two ways to do that. The first works without even opening the email. You can also deactivate a message from the answer menu.
If you are in the inbox, slide your finger on an email and select the "More" option.
In the pop-up window, press the "Mute" button.
The email will now have a small "Bell" icon to inform you that the thread has been muted.
If the e-mail is already open, press the "Reply" button in the lower right corner.
Then scroll down a little until you see the option "Mute". Press the button to cut the thread.
If you want to reactivate the thread later, follow the same process and press the "Disable" option.
How to disable chat threads on Mac
Open the Mail application on your Mac running. macOS Catalina. Then select an email or several emails. In the top toolbar, locate the "Bell" icon and click on it.
The icon will become a bell icon with a dash through it. This means that the conversation has been muted.
You can also mute a conversation by right-clicking an email in the list and selecting the "Mute" option.
To reactivate a thread, click the "Disable" button again on the toolbar.
