Braze

Braze coordinates email, push notifications, and in-app messages based on real-time user behavior. Instead of separate email campaigns, you orchestrate journeys where users receive the right message on the right channel at the right moment. The platform updates instantly as users interact with your product, making personalization both granular and responsive.

It's widely adopted by SaaS companies that need sophisticated multi-channel campaigns and product teams that want messaging to react to in-app activity. The setup takes time, but the payoff is higher engagement and clearer attribution of messages to user outcomes.
