});Route intelligence
Move traffic when a carrier lane slows down, without manual escalation or customer-facing delays.
Failed messages are never charged, and every debit maps back to a delivery status.
Track submitted, delivered, failed, pending, routed, and debited counts per campaign.
Use 2-way short codes for support, opt-ins, balance checks, complaint logging, and status updates. Add phone verification when you need a stronger path for fintech, betting, lending, marketplace, and recovery flows where ordinary OTP delivery causes drop-off.
