Platform Operations

Built for carrier-grade throughput and visibility.

CoastNex runs the routing, compliance, and monitoring layer behind every message — so your team gets predictable delivery across global A2P routes without operating carrier infrastructure directly.

Intelligent least-cost routing engine

Every message is scored across carrier routes in real time, balancing cost, quality, and delivery speed on wholesale A2P routes.

Real-time DLR analytics

Delivery receipts stream back as structured events, giving your team live visibility into delivery rates by carrier and country.

Compliance & consent tooling

Built-in consent capture, opt-out handling, and sender ID governance keep cross-border campaigns compliant by default.

SMPP 3.4 + REST API connectivity

Connect however your stack is built — a modern REST API for application teams, SMPP 3.4 binds for high-volume carrier integration.

Throughput up to 10k MPS

Scale campaigns and OTP bursts to 10,000 messages per second without re-architecting your integration.

24/7 NOC monitoring

A dedicated network operations team watches route health and latency around the clock, every day of the year.
