Braze

Braze is built for large organizations managing customer engagement at scale across millions of users. Canvas Flow lets you map complex, multi-stage journeys where SMS, email, and push work together, with rules that optimize delivery timing and frequency per customer. The platform handles high-volume sending with detailed performance tracking and A/B testing across channels.

Best for mid-market and enterprise teams with sophisticated engagement strategies. Braze shines when you need advanced segmentation, frequency capping, and orchestration tools that treat SMS as one part of a holistic customer journey rather than an isolated channel.
