Reach every customer on the channel they already use.

Pair a number in seconds and keep it paired. Sessions are supervised, reconnected and reported on, so a dropped socket is an alert rather than a silence.

Every send is queued, rate limited and retried on its own terms. Pause, resume or cancel mid-flight and the recipients who have not gone out simply stop.

Subscription quota for WhatsApp, prepaid credits for SMS and Voice, and a double-entry ledger underneath both. Every charge traces back to the message that caused it.
