Transactional SMS Marketing FAQs

What is transactional SMS?

Transactional SMS is an automated, non-promotional message triggered by a specific customer action or event, such as an order confirmation, OTP, shipping update, or account alert. Unlike promotional SMS, these messages are not designed to sell but to inform and build trust.

What is the difference between transactional and promotional SMS?

Promotional SMS is used to market products, offers, and campaigns. Transactional SMS delivers critical, action-triggered information that customers are expecting, and in many markets, does not require the same opt-in consent as promotional messaging. Always verify the regulatory requirements in your specific markets before sending.

Which industries benefit most from transactional SMS?

Retail, banking, healthcare, food delivery, and automotive are among the strongest use cases, but any industry that needs to communicate timely, action-triggered updates to customers can benefit from transactional SMS.
