Mute a user

You can mute any user you do not wish to interact with. Muting someone will have the following effects:

Combined feed sent by a muted user will automatically be marked as read for you, and will never generate any desktop, email, or mobile push notifications.
Combined feed sent by muted users, including the name, profile picture, and message content, are hidden behind a Click here to reveal banner. A revealed message can later be re-hidden.
Muted users are hidden from direct messages in the left sidebar and the list of users in the right sidebar. Direct messages between you and a muted user are excluded from all views, including search, unless you explicitly search for dm-with:<that user>.
Muted users have their name displayed as “Muted user” for emoji reactions, polls, and when displaying the recipients of group direct messages.
Muted users are excluded from the autocomplete for composing a direct message or mentioning a user.
Muted users are excluded from read receipts for all messages. Zulip never shares whether or not you have read a message with a user you’ve muted.
Recent conversations and other features that display avatars will show a generic user symbol in place of a muted user’s profile picture.
To avoid interfering with administration tasks, channel and organization settings display muted users’ names and other details.

Hover over a user’s name in the right sidebar.
Click on their avatar or the ellipsis () to the right of their name to open their user card.
Click on the ellipsis () in the user card.
Click Mute this user.
On the confirmation popup, click Confirm.
