What is Transactional SMS?
Transactional SMS refers to text messages sent to customers for informational purposes. These are typically system-generated and triggered by user actions or system updates. Think OTPs (One-Time Passwords), account activity alerts, payment confirmations, or order tracking updates.
Unlike promotional SMS, which markets products or services, transactional messages provide critical and real-time information, often essential to user security and operational transparency.
