DocMorris, Germany's leading digital pharmacy with 12.2M active customers, swapped a fragmented, campaign-driven stack for a real-time, app-first engagement model on Braze.

You'll see the architecture, the live use cases, and the hard numbers, what's working and driving revenue and what didn't work out. Three practical examples and live results.
