Pick the pipe — then the brain

Push without architecture is just noise with a badge. On iOS you still speak APNs. On Android you still speak FCM. Everything else is how you orchestrate.

Recommendation: Firebase + OneSignal — or Firebase + Bloomreach.

Firebase + OneSignal — solid default for many lottery teams: FCM/APNs under the hood, OneSignal for campaigns, segments, and speed without a CDP tax.

Firebase + Bloomreach — when you want push customized the way you customize email: richer journeys, templates, and cross-channel consistency. If Bloomreach already runs email, push can match that brain.

On a budget: stay on Firebase, add Cloud Functions, and keep user preferences in Firestore with the device ID attached so you can target users directly. No second SaaS required to send a responsible, preference-aware push.

Also in the market: Braze and Airship for heavy engagement suites; Amazon SNS when you’re AWS-native and willing to own more plumbing. None of them replace consent, frequency caps, or responsible-play rules.

Jackpot alerts that ignore quiet hours aren’t “engagement.” They’re how you train players to disable notifications — or delete the app.
