What is
Transactional SMS?
Understanding telecom routing classes, the strict differences between transactional and promotional messaging, and why it critically impacts your software's reliability.
The Core Definition
Transactional SMS refers to automated, non-marketing text messages sent to individuals to facilitate, complete, or confirm a commercial transaction or account action that the recipient has initiated.
Unlike bulk marketing messages, transactional messages are sent on a strict one-to-one basis through high-priority telecom routes to ensure delivery within seconds.
Examples of Transactional Messages
- Authentication: One-Time Passwords (OTPs) for login or 2FA password resets.
- E-Commerce: Order placement confirmations and courier dispatch alerts.
- Banking: Real-time debit/credit transaction alerts and account notifications.
- Logistics: Real-time rider updates for food or ride-hailing delivery.
Why Dedicated Routing Matters
In Nepal, telecom operators process bulk promotional marketing traffic separately from critical transactional traffic. Blending your application's OTPs into promotional queues causes severe delivery delays and causes messages to be blocked by Do-Not-Disturb (DND) registries.
