Muted channels and DMs are greyed out at the bottom of your channel list.
Other people can't see which channels and DMs you've muted.
You'll see a numbered badge 1 next to conversations that you've muted in your sidebar if you’ve been mentioned or received a DM.
The Threads view at the top of your sidebar will appear in bold if someone creates or replies to a thread from any message that you've sent in a muted conversation.
Note:It’s not possible to mute notifications from Slackbot.
