Emojis are small, digital images or icons you can use to communicate or express concepts such as emotions and physical gestures in your messages.

From Mattermost v6.1 and in Mattermost Cloud, you can react to messages quickly by selecting a recently used emoji. Recent emojis are sorted based on the number of times you’ve used the emoji. If your most recent reactions aren’t visible, you can enable quick reactions by selecting Settings > Display > Quick reactions on messages.

Select the Smile icon Smile icon inside the Mattermost message input box to open the emoji picker. If the existing emojis available in Mattermost don’t cover what you want to express, you can also upload your own custom emoji.
