Everything you need to reach a user, push, email, in-app, and deep links, on your own infrastructure.
01
Your own FCM credentials
Reach Android and iOS devices through your own Firebase project — FCM relays to APNs for iOS. Retainza batches sends, prunes dead tokens automatically, and never owns your deliverability.
02
Any SMTP, provider-agnostic
Send through any SMTP provider with nodemailer. Rich HTML with plain-text fallback, throttled to your provider's rate. SPF/DKIM guidance built in.
03
Five layouts, rendered for you
Modal, banner, full-screen, bottom-sheet and custom HTML — all rendered by the SDK, styled from the dashboard. Or take the payload yourself and draw it however you like.
04
Route users to any screen
Every message can carry a route — a screen name plus key/value params. Your app maps it to its own navigator, so a tap lands users exactly where you want them.
Built into the dashboard next to Campaigns, Segments and Templates. Scoped to your project. Nothing sends without your confirmation.
01
Look at campaigns, sends, segments, analytics and usage in the current project, ask why a send missed people.
02
Create campaigns, segments or templates for review. Everything lands as draft; you publish in the normal editor.
03
Send, pause, activate or delete only after you click Confirm within 5 minutes. The assistant proposes, never executes alone.
Every draft and confirm action is logged on Activity. Billing, credentials and team settings stay on the normal screens, Ask AI cannot change them.
A TypeScript core with thin wrappers for Web, React Native and Node. You keep full control of rendering and navigation, Retainza just hands you the message and the route.
import { Retainza } from "@retainza/react-native";
const engage = Retainza.init({
publicKey: "pk_live_…",
userProvider: () => auth.currentUser?.uid,
});
// Identify + track
await engage.identify(uid, { trial_days_left: 3, locale: "de" });
engage.track("opened_paywall");
// Render in-app messages + handle deep links, your way
engage.onInApp((msg) => showModal(msg));
engage.onNavigate((route) => router.push(route));The principles that shape every line of the platform.
01
The Project is the isolation boundary. Every write is scoped by projectId; nothing about one tenant is ever reachable by another.
02
Each project connects its own FCM and SMTP. Retainza sends on your behalf and never owns delivery cost or deliverability.
03
Credentials never touch the database in plaintext, only a reference, backed by Secret Manager + per-project KMS envelope encryption.
04
Store and Channel adapter seams mean Firestore→Postgres and Functions→Run are swaps, not rewrites.
