Did you know you can give your emote artists credit directly on Twitch?
All you gotta do is go to your Creator dashboard, click on viewer rewards and then emotes. When you're there you will see a page like this with all your emotes and their names.
To add credit to an existing emote, click on the emote and go down to the emote attribution field and enter the username of your emote artist!
Their twitch should pop up in a list of similar usernames as soon as you start typing, and then they will have to manually approve it. This field is also accessible when uploading a new emote! Attributed artists show up when someone clicks and emote in chat, meaning you'll be spreading the love for your artist even in other people's streams if your emote gets used! It only takes a second and it goes a long way!
