Notifications support all of Discord's text formatting which means that you can make your announcements stand out however you want.
The dashboard allows you to customize notifications on a whole different level. You can choose the option to use a small embed (no stream preview) or no embed at all. Embed color is also customizable, so if you don't like the standard "Twitch purple," it can be changed to whatever fits best.
