In the context of Bulk SMS marketing, message delivery has been regulated and controlled
because of increased fears about spam and privacy of users. One of the most
critical steps towards legally and effectively sending promotion or
transactional SMS in India is via DLT
Template Registration. If you are new to DLT or find it challenging to get your SMS Templates approved, this comprehensive guide will educate you about
the process, significance and how to achieve it efficiently with Xcelmarketing, a premier Bulk SMS service provider in India.
DLT (Distributed Ledger Technology) is a block chain-based registry
system ordered by TRAI (Telecom Regulatory Authority of India) to manage
unwanted commercial communication (UCC). It provides transparency and
accountability in sending business messages like SMS Campaigns.
If you are a company sending Bulk SMS for transaction or marketing
messages, then first of all, you need to do DLT Registration. Then you require approval for your SMS Templates on the DLT Portal of operators such as Jio,
Vodafone-Idea, BSNL and Airtel.

1.
Following TRAI guidelines: Prevent penalties and legal
problems.
2.
Improved message deliverability: Registered messages get filtered
very seldom.
3.
Brand authentication: Prescribed templates are your
official identity.
4.
Prevention of SMS blocking: Only pre-approved content templates
can reach the operator's firewall.
5.
Improved customer trust: It lessens the risk of being marked
as spam.

Recognizing the types of SMS Templates is crucial to successful DLT Template Registration. Below are the principal categories:
For sending marketing offers or messages to
potential customers who have subscribed.
Example:
"Get 25% OFF on your first online order.
Shop now! XYZBrand."
Used by organizations, schools, or banks to
send transaction information to subscribers.
Example:
"Your OTP for login is 456789. Valid for 5
minutes, do not share it with anyone."
·
Customer
service-related messages with no marketing message.
Example:
"Your ticket has been successfully booked.
Enjoy your trip!"
·
Service-related
messages that contain promotional intent.
Example:
"We noticed your subscription is ending.
Renew now and get 15% off!"
Every business must categorize the SMS correctly
when registering it on the DLT Portal
to avoid rejection.

Here's a step-by-step process to get your SMS Templates approved through a DLT Portal:
You need to be registered on the DLT Portal before you file templates.
Select any telecom operator such as Jio, Airtel, or BSNL to begin.
Documents needed:
·
PAN
card
·
GST
certificate
·
Business
proof
·
Authorization
letter
·
Header
(Sender ID) registration
After you finish DLT Registration, you'll be provided with login credentials for the
DLT Portal.
Headers are the alphanumeric names (such as
TM-ABCSMS) that users see when they receive an SMS. You will have to register
your own unique Header for promotional or transactional messages.
Ensure:
·
Use
distinctive headers for various message types.
·
Do
not use generic or confusing names.
·
Assure
header is consistent with brand identity.
Now, login to your DLT Portal, go to Template
Registration and submit your message templates. Provide:
·
Template
Name
·
Header
·
Message
content (with or without variables)
·
Category
(Promotional/Transactional/Service)
·
Language
Variables should be highlighted using double
curly braces `{variable}` for dynamic content.
Example:
"Your OTP is {otp} for login."
Approval might take 24–72 hours based on
operator load. Make sure all template content is as per guidelines.
Even after providing the correct documents and
format templates are rejected for common mistakes. Here's what not to do:
1.
Incorrect template format: Failure to apply correct variable
placeholders such as `{name}`.
2.
Mismatch with header: Make sure your content and header
match your registered business name.
3.
Promotional content under
Transactional:
Merging categories means rejection.
4.
Grammar errors or unprofessional
content:
Low-quality messages can be rejected.
5.
Use of prohibited keywords: Don't use words such as
"free", "click here", or other misleading words.
6.
Duplicate template names: Provide distinct names for every
submission.
