Well, I'm using OneSignal to send notificaitions to the users of my Android app and it's working fine. Moreover, it uses FCM as its base. So, that shouldn't be a problem too. You can segment users thet way you want and send notifications to one or many - upto you. It's all for free and very easy to set up the basics of it. It's here: OneSignal
