Reach customers on the channel they actually use.
Seven ways to deliver a message — each with its own strengths, all behind one consistent API. Mix them, order them, and let ComniCube fall back automatically when one doesn't land.
SMS
Reach any phone on the planet, instantly — no app required.
The world's most-opened messaging channel, fully managed.
Viber
3× higher open rates across Eastern Europe and the Middle East.
Voice
A real call, delivered at scale — for messages that must be heard.
Push
Lock-screen reach on iOS and Android with zero per-message cost.
Transactional email from the same API, tuned for deliverability.
Order your channels. We handle the rest.
Pass an ordered list of channels and ComniCube attempts each in turn — moving to the next the instant one degrades, all within a single request and a single set of webhooks.
Which channel for which job.
A quick reference for the trade-offs. In practice, most teams combine several and let routing decide.
| Channel | Best for | Global reach | Rich media | 2-way | Relative cost |

One-time passcodes that always arrive.
Verify is a managed OTP product built on the same gateway. Send a code, we pick the fastest channel, retry across channels on failure, and check the result — in two API calls.
