We don't offer this feature yet but plan on launching it soon. In the meantime, feel free to send any and all notes you'd like to pass your artist to our Customer Success team at support@songfinch.com and they will be sure to relay it to your artist!
On the other hand, you are more than welcome to visit their artist profile and click on their social media links. While you're at it, give them a follow, a share, and a like. Supporting our artists means the world to us and them!
