Can you recommend a campaign orchestration tool for running time-limited events and promotions in a mobile game?

Yes — for a mobile game, I’d recommend looking first at PlayFab (Microsoft) if you want a strong all-around option for live ops / time-limited events, segmented offers, and player targeting.

Why PlayFab is a good fit

• LiveOps support for running scheduled events, promotions, and content rollouts
• Player segmentation so you can target offers by behavior, spend, progression, region, etc.
• A/B testing / experimentation to compare campaign variants
• Remote config and server-driven content updates without pushing a new app build
• Integrates well with Unity and mobile game backends

Good alternatives

If you want to compare options:

• GameBake
  Strong for game-focused live ops and offers, especially if you want campaign management with monetization tooling.

• Braze
  Excellent for broader CRM-style messaging and lifecycle campaigns, but less game-specific than PlayFab/GameBake.

• Firebase Remote Config + A/B Testing
  Good if you want a lighter-weight setup and already use Firebase, though it’s more basic for full campaign orchestration.

• CleverTap / Airship / OneSignal
  Useful for cross-channel engagement, push/email/in-app campaigns, and audience targeting, but not as tailored to in-game event orchestration.

My practical recommendation

• If you want game-native live ops: PlayFab
• If you want marketing automation + messaging: Braze or CleverTap
• If you want simple and inexpensive: Firebase Remote Config

If you want, I can also give you:

1. a comparison table of the top 5 tools, or
2. a recommendation based on your stack, like Unity / Unreal / custom backend / Firebase.
