Have you ever received an SMS when you tried to log in to your bank or order something online? That type of SMS is called a Transactional SMS in India. These messages are very important because they help businesses talk to customers safely, quickly, and without delays. They are not for ads or promotions. Instead, they share helpful information like OTPs (One-Time Passwords), alerts, and real-time updates.
What is Transactional SMS?
A Transactional SMS is a type of message that businesses send to customers to give important information. These messages are not promotional. This means they are not for marketing or selling. Instead, they help users with alerts, OTPs, and confirmations.
For example:
- Bank alerts for money deposits or withdrawals
- OTP messages to log in or reset passwords
- Order status or delivery updates from shopping apps
- School attendance messages for parents
- Ticket confirmation for flights, trains, or buses
Types of Transactional SMS
There are mainly two types of transactional messages:
- OTP SMS: These messages give a One-Time Password to users to verify their identity.
- Informational SMS: These are alerts, reminders, or updates like account balance or ticket booking status.
