03Under the hood
Everything that has to work, working.
Delivery receipts, failover, DLT paperwork and a person who answers — the parts that decide whether a message actually lands.

Your order 4821 has shipped. Track: msgb.in/t/4821
Delivery you can prove
Operator-end delivery reports come back over the API, not a dashboard you have to refresh.
Cascading failover
SMS, then WhatsApp, then a voice call — until the code lands.
Registering…
DLT, handled
Entity, header, template and TM chain binding — run in parallel with your build.
One API, five channels
One contract, one integration, one invoice. Add a channel without adding a vendor.
Hi {{name}}, your order {{order_id}} is out for delivery.
Templates that pass first time
We draft the content template so the variables match what your code actually sends.

A named person answers
Not a ticket number. Support on WhatsApp during business hours, with a response commitment.
04Channels
Five channels. One contract, one invoice, one team to call.
05The channel ladder
The same message, three ways.
Start on SMS. Upgrade to WhatsApp for buttons and media. Move to RCS for a fully branded card — without changing your integration.
