Q: What is the difference between Bulk SMS and TXN SMS?

Bulk SMS is typically used for promotional marketing campaigns sent to large audiences. TXN SMS (Transactional SMS) is used exclusively for time-sensitive, secure alerts like Bank OTPs, order updates, and system notifications with bypassed DND restrictions.

TXN SMS & OTP Pipelines

While promotional campaigns drive growth, TXN SMS (Transactional SMS) drives trust. When a user requests a Bank OTP, a password reset, or vital server-down alert, latency can kill conversion rates. Our dedicated TXN SMS gateways are physically separated from promotional traffic queues, seamlessly penetrating DND (Do Not Disturb) logic natively and securely.
