Whisperr
Whisperr replaces campaign building with per-user decisions. It reads each user’s product events and subscription events from RevenueCat, Superwall or Adapty, decides whether a retention message would help, writes it for that user, and sends it by push or email through your own providers. A 10% holdout group shows how many users it kept once each group has 200 users. Choose it if you want retention to run without a lifecycle team. Whisperr vs Braze.

FAQ
Why do subscription apps look for a Braze alternative?
Braze sells through sales quotes with no free plan, and Canvas journeys take a team to build and maintain. A smaller app may want a cheaper campaign tool, or retention that runs without a lifecycle team.

How much setup does Whisperr need?

CleverTap covers push, email, WhatsApp, in-app, web, RCS and SMS. Customer.io covers email, push, SMS, in-app, WhatsApp and LINE. Airship covers push, SMS, email, in-app, web and mobile wallet. Whisperr sends push and email.
