MARKETING: Unity Game (not only engine). Tool for Push notifications.

Hi there!
We have a game totally made in Unity. I want to show notifications for user inside the game (for example, a discount offer or a custom welcome).
Do you know a Marketing tool that allows me to do so?

Thanks

You need a backend server like PlayFab.

Push Notifications is one of PlayFab’s features and its free of charge:

You can Google “game backend as a service” to find more providers. I mentioned PlayFab, because it’s the one I’m planning to move to (no experience with it yet).
