The platform

Engineered for messages that matter.

Marketing tools optimise for clicks. ComniCube optimises for delivery — the OTP that has to arrive, the alert that can't wait, the receipt your customer is expecting.

Intelligent failover

If a route degrades, ComniCube reroutes across carriers — or to an entirely different channel — in under 300ms. Your message gets through.

Least-cost smart routing

Every message takes the lowest-cost path that still meets your deliverability threshold, evaluated per destination in real time.

Real-time delivery insight

Delivery receipts, engagement events, and failures stream back over webhooks the moment they happen — no polling, no guesswork.

Global carrier mesh

1,200+ direct carrier connections across 200+ countries, with local sender IDs and number provisioning built in.

Compliance by default

Consent tracking, automatic opt-out handling, sender ID registration, and regional regulation handled at the gateway.

One API, every channel

Send, receive, and track across all seven channels with one consistent interface. Add a channel by changing a single parameter.

How it works

From your app to their pocket — in one hop.

You make one request. ComniCube handles carrier selection, formatting, failover, and delivery tracking across the entire global mesh.

01

Send once

A single authenticated request specifies your recipient, content, and an ordered list of channels to try.

02

Route intelligently

The engine scores every available path on cost and deliverability, then dispatches — falling back automatically if a route fails.

03

Track everything

Status updates flow back over webhooks in real time, with a complete audit trail for every attempt on every channel.

Use cases
