About Zavu is one API for all your messages, built to send and receive SMS, WhatsApp, Email, Voice, Telegram, and more from a single integration. It helps developers ship messaging instead of maintaining messaging infrastructure, replacing separate APIs, SDKs, auth models, webhook formats, sender setup, template approvals, and error handling with one SDK, one webhook format, and one dashboard. Zavu is also built for AI agents from day one: agents can send SMS, WhatsApp, Email, and Voice globally, while developers can use production-ready SDKs across languages such as Node.js, Python, Ruby, Go, PHP, and Java. Its Smart Send and AI Routing features pick SMS, WhatsApp, or Email per contact, choose the best or cheapest delivery path using platform-wide delivery intelligence, and fall back automatically when a channel fails. Context is preserved, delivery is deduplicated, and cost is tracked end-to-end across the fallback chain.
