A delayed SMS is a call-centre spike waiting to happen.
A delayed dispatch SMS means a call-centre spike. A lost delivery OTP means a returned package. Multi-language drivers and customers need messaging in their language, not in corporate English.
Most generic SMS platforms weren't designed for last-mile chaos in India — carrier flakiness, DND restrictions, and a workforce that doesn't read English. You need routing that compensates for all three automatically.
8 languages
supported for two-way WhatsApp driver flows — so the person actually dispatching your package understands every instruction.
Messaging that matches how Indian logistics actually runs.
API-driven dispatches, priority OTPs, live tracking links, and two-way WhatsApp flows for drivers and customers.
Dispatch and delivery SMS
Auto-triggered from your WMS or TMS via API, with DLT-approved templates and smart route failover to keep the 7pm blast on time.
Delivery OTPs on a priority route
Typically 98% under 1 sec on clean DLT traffic, DND-exempt via transactional template, with automatic retry on failure.
Live-tracking links
Send a tap-through tracking link over SMS or WhatsApp. Customers stop calling the hub for ETAs.
Driver WhatsApp flows
Two-way WhatsApp for pickup confirmation, issue escalation, and shift check-in — in the language each driver speaks.
Every touchpoint between dispatch and delivery.
- Order confirmation with expected delivery window
- Out-for-delivery SMS with live tracking link
- Delivery OTP for identity verification
- Delivery complete confirmation
- Return pickup scheduled alerts
- Driver shift start and end check-ins
- Exception alerts — delayed, cancelled, re-routed
- COD payment confirmations
What operations and tech teams usually ask us.
Can I integrate with my WMS or TMS?
Yes — via our REST API and webhooks. Dispatches, status changes, and exceptions can all fire messages automatically.
What is the OTP delivery success rate?
Typically 98–99% on clean DLT traffic with sub-second median delivery. OTP traffic runs on a priority route isolated from promotional bulk.
Can drivers respond in regional languages?
Yes, via WhatsApp. The AI agent replies in 8 Indian languages today — Hindi, English, Tamil, Telugu, Bengali, Marathi, Gujarati, and Kannada. Malayalam, Punjabi, and Urdu are on the near-term roadmap. The shared inbox accepts any Unicode script, so your human agents can reply in a wider set of languages than the AI covers.
Can I fail over between carriers automatically?
Yes. Smart route failover switches operators on carrier issues, so a Mumbai dispatch at 7 PM still lands even if a single SMSC degrades.

E-commerce and retail teams use the same delivery loops. The developer hub covers webhook patterns for carrier events.
