What is Transactional SMS?
Transactional SMS refers to automated, system-triggered messages sent to customers to deliver critical, time-sensitive information. Unlike promotional SMS — which is marketing-oriented and restricted by DND rules — transactional SMS is initiated by a specific customer action or system event, such as a login attempt, payment, appointment booking, or account update. These messages are delivered immediately, around the clock, even to numbers registered on India’s DND list.
Businesses across banking, healthcare, e-commerce, fintech, and education rely on transactional SMS to send OTP verification codes, payment alerts, service notifications, and security warnings. Because these messages are expected by the customer and directly tied to their actions, they carry exceptionally high open and read rates — making transactional SMS one of the most trusted and effective communication channels in India.
