What is Transactional SMS?

A non-promotional text message sent to a customer triggered by a specific action or system event, such as an OTP, order confirmation, or payment receipt.

Transactional SMS messages are a critical part of modern business communication. Unlike promotional SMS, these messages are directly tied to a user's interaction with a business—such as completing a purchase, logging into an account, or receiving a delivery. Because they contain information the recipient expects or needs, transactional SMS is exempt from DND (Do Not Disturb) restrictions in India and can be sent 24/7. Businesses across banking, e-commerce, healthcare, and logistics rely on transactional SMS to deliver OTPs, account alerts, booking confirmations, and shipping updates instantly. With BhashSMS, transactional SMS messages are delivered through a dedicated high-priority route, ensuring near-instant delivery even during peak traffic.
