Core Architecture
Built for Developer Velocity & Scale
Smart Provider Failover
Define backup providers per channel. If primary provider latency spikes or returns 5xx errors, NotifySetu automatically reroutes payload.
Universal Template Engine
Store and version your email HTML, SMS copy, and WhatsApp templates in one place with variables and conditional rendering.
Real-time Webhook Delivery
Stream all notification lifecycle events (dispatched, delivered, opened, failed) directly to your webhooks with HMAC signatures.
Multi-Tenant Workspaces
Isolate production, staging, and development environments with granular API keys and role-based access control.
Unified Analytics Dashboard
Gain full visibility into provider delivery rates, latency metrics, channel usage costs, and failure diagnostics.
Enterprise Encryption & Security
All payload variables and API keys are encrypted at rest with AES-256 and in transit with TLS 1.3.
