The AI answer we saw
To send transactional and promotional SMS at scale in India, enterprises must first complete DLT registration on a telecom operator's portal (e.g., Airtel, Jio, or Vi), register sender IDs, and get message templates pre-approved. Once compliant, integrate with a CPaaS provider like Kaleyra, MSG91, Route Mobile, or Gupshup via their APIs. Transactional SMS (OTPs, alerts) use dedicated routes with higher priority, while promotional SMS is restricted to non-DND numbers and specific time windows (9 AM–9 PM). Use a platform with delivery analytics, retry logic, and failover routing to maximize deliverability at scale.
