Muting notifications for words and hashtags
You might be mentioned in Tweets alongside content you’d like to avoid. We give you the option to mute notifications for Tweets you are mentioned in that contain particular words, phrases, usernames, emojis or hashtags. Muting will remove these Tweets from your Notifications tab, push notifications, SMS, and email notifications.
Note: Muting words and hashtags only applies to your notifications. You will still see these Tweets in your timeline and via search. The muted words and hashtags are applied to replies and mentions, including all interactions on those replies and mentions: likes, Retweets, additional replies, and Quote Tweets.

- Muting is case-insensitive. For example:
If you add “CATS” to your mute list, any mention of “cats” will be muted from your notifications.- You can include punctuation within a word or phrase when muting. Punctuation at the end of a word or phrase is not necessary.
- Muting a word will mute both the word itself and its hashtag. For example:
If you mute “unicorn”, both “unicorn” and “#unicorn” will be muted from your notifications.- To mute Tweet notifications that mention a particular account, you must include the @ sign before the name. Doing this will mute Tweet notifications that mention that account, but won’t mute notifications from the account itself. Learn about how to mute accounts here.
- Words, phrases, usernames, emojis, and hashtags up to 140 characters can be muted.
- Muting is possible across all Twitter-supported languages.
- Muting cannot be set for a particular time period. Words and phrases will remain muted until manually deleted from your settings.
- You can view a list of your muted words (and unmute them) in your settings.
