Custom Emoji. Premium users can include unique animated emoji in messages and captions to add even more expression to chats.

Open the emoji tab of the sticker panel to browse your packs or add new ones. You can tap a message to view and add the packs it's using (press and hold on iOS).

Emoji are an open platform – anyone can upload custom packs with their artwork. All users can see any custom emoji and use them in their Saved Messages.
