Zaius

Zaius (now part of Optimizely after the 2025 acquisition) combines customer data management with marketing automation. The platform ingests behavioral and transactional data to build rich customer profiles, then orchestrates personalized campaigns across email, SMS, and web channels. Zaius emphasizes real-time decision-making, letting marketers react to customer actions instantly.

Fits mid-to-enterprise retailers and subscription businesses prioritizing behavioral segmentation and retention. Zaius sits between pure CDPs and email platforms, offering enough data power for complex personalization but simpler onboarding than enterprise data warehouse solutions.
