Have you ever gotten a text from your bank telling you that money was added to your account? Or a message from your school saying your exam results are out? These messages are not sent by one person typing on a phone. They are sent using something called Transactional Bulk SMS. It’s like a super-smart way to send useful information to many people at the same time. And guess what? We are really good at doing this!
SMS in Simple Words
SMS stands for Short Message Service. It means sending a short message or text from one phone to another. But when we talk about bulk SMS, we mean sending one message to a lot of phones at once. There are two types of bulk SMS: Promotional SMS and Transactional SMS.
So, What is Transactional Bulk SMS?
Transactional Bulk SMS is used to send important and useful messages. These messages give information that people really need to know. It is not for selling things. Instead, it helps people stay informed.
For example:
- Your bank sends you a message when money is added or taken from your account.
- Your school tells your parents that you are absent today.
- Your hospital sends you a message about your appointment tomorrow.
These types of messages are allowed to be sent even at night or on holidays because they are useful. That’s why they are called “transactional”.
Who Uses Transactional Bulk SMS?
So many people and places use transactional SMS! Here are some examples:
- Hospitals – for sending appointment reminders.
- Schools – for informing about holidays, events, or student performance.
- Banks – for alerting about money deposits or ATM usage.
- Online Shopping Sites – for sharing order tracking details.
- Airlines – for sending flight updates.
DLT Rules for Transactional SMS Templates
Why this matters: In India, every Entity must comply with TRAI’s DLT framework before sending transactional SMS. Getting these right prevents blocking and improves deliverability.
What qualifies as “Transactional”
- Purely informational or service messages (e.g., OTPs, order updates, appointment reminders).
- No marketing language, discounts, or promotional CTAs inside the template.
Must-have compliance items
- Registered Entity on a DLT portal (e.g., Jio/Airtel/Vi).
- Approved Header (Sender ID): 6 characters, mapped to your business/vertical.
- Approved Content Templates:
- Keep the core text fixed; use variables like
{#var#}only where needed. - Variables must not change the intent (don’t sneak in promotions).
- Don’t use URL shorteners that hide the destination (use branded/clear URLs if required).
- Keep the core text fixed; use variables like
- Category Selection: Choose “Transactional/Service/OTP” (as applicable) while submitting.
- PE–TM Binding: Ensure your Principal Entity is correctly linked to your Telemarketer.
- DND Delivery: Transactional routes deliver 24×7 and reach DND numbers (still avoid marketing content).
Good template vs. risky template
- ✅ Good: “Dear {#var#}, your order {#var#} will be delivered on {#var#}. Track: {#var#}”
- ❌ Risky (promotional): “Hurry! 20% OFF on your renewal. Pay now: {#var#}”
Helpful additions
- Add support contact or ticket link for service clarity.
- Keep tone neutral, avoid urgency words typical of promotions (e.g., “limited offer”, “flash sale”).
