Transactional SMS vs OTP SMS vs Promotional SMS (When to Use What)

Choose Transactional SMS when the message is urgent, time-sensitive, and must reach users quickly, like OTPs, fraud alerts, and status updates.

Channel Best For Transactional Use Limitations Turain Hybrid Strategy
Transactional SMS Critical alerts, confirmations, updates, anytime messages, DND reach Plain text only; less rich media; may incur higher priority route costs Use when delivery and immediacy matter; add WhatsApp/Voice for richer content if needed
OTP SMS Very time-sensitive authentication / verification Strict regulatory rules; short lifespan OTP handled separately; transactional SMS covers non-OTP critical notifications
Bulk (Promotional) SMS Marketing, offers, promotions Time windows, opt-in requirements, lower priority on DND Use for marketing; never mix with transactional messaging
Voice / IVR / WhatsApp etc. Voice, interactivity or media; user preference channels Higher cost; device/app dependency; possible latency Use Transactional SMS + fallback to WhatsApp/Voice for richer notifications if required
