Definition
Transactional SMS is any message sent as part of a transaction, operation, or relationship between a company and a customer. Examples: verification code, order confirmation, bank alert, appointment reminder, delivery notification.
Difference between transactional and marketing SMS
Transactional SMS responds to a user action or need (e.g., purchased, scheduled, requested login). Marketing SMS sends promotions without a recent customer action. The legal basis and opt-in rules differ.
