24/7 Automated Transactional SMS Gateway for Business Alerts
Deliver essential customer notifications, order confirmations, billing receipts, booking alerts, and ERP dispatches instantly across India. High-throughput automated messaging built for maximum delivery reliability.
Transactional SMS refers to automated, intent-driven text messages sent to customers to convey vital, non-marketing information. These messages are triggered by specific user interactions—such as completing an e-commerce order, requesting an account statement, booking a flight ticket, or receiving an emergency operational alert.
Unlike promotional broadcasts that pitch offers or sales discounts, transactional SMS is informative in nature. Under Indian regulations, it falls primarily under Service Implicit (essential account alerts, bills, transactions) and Service Explicit (updates based on prior customer consent).
"Dear Customer, your order #49281 has been dispatched with tracking ID BLR8930. Expected delivery: Tomorrow."

"Reminder: Your dental consultation is confirmed for Oct 12, 10:30 AM at Indiranagar Clinic."
