Zulip lets you mute topics and channels to avoid receiving notifications for messages you are not interested in. Muting a channel effectively mutes all topics in that channel. You can also manually **mute** a topic in an unmuted channel, or **unmute** a topic in a muted channel. Muting has the following effects: - Messages in muted topics do not generate notifications (including [alert word](/help/dm-mention-alert-notifications#alert-words) notifications), unless you are [mentioned](/help/mention-a-user-or-group). - Messages in muted topics do not appear in the [**Combined feed** view](/help/combined-feed) or the mobile **Inbox** view. - Muted topics appear in the [**Recent conversations** view](/help/recent-conversations) only if the **Include muted** filter is enabled. - Unread messages in muted topics do not contribute to channel unread counts. - Muted topics and channels are grayed out in the left sidebar of the desktop/web app, and in the mobile app. - In the desktop/web app, muted topics are sorted to the bottom of their channel, and muted channels are sorted to the bottom of their channel section. !!! warn "" **Note**: Some parts of the Zulip experience may start to degrade if you receive more than a few hundred muted messages a day.
