Alerts can even include sound effects for each, adding just another way to customize and impress your viewers. You can even take these further by adding variations to donations over a certain amount, or a subscriber that’s been around for a longer period of time. You might have one alert for a new donation and another alert for a new Twitch subscriber. This is because sites like Streamlabs and StreamElements offer different variations and coding capabilities for this type of overlay element. While labels are more of a static reminder of your latest supporters, alerts can be dynamic when added to your stream overlay. If you’ve seen a stream, then you probably have seen alert notifications and widgets.
