Understanding the Legal Risks of SMS Campaigns in India
One Wrong Text Could Cost You More Than You Think
Let’s start with a truth no one talks about enough — SMS marketing in India is a beast. It’s powerful, it’s immediate, and if done right, it delivers ROI that most channels can’t compete with. But here’s the flip side: it’s also heavily regulated. And when you overlook the legal framework? You don’t just lose customers. You risk losing your brand’s credibility — or worse, facing fines, blacklisting, or permanent bans.
Yes, it’s that serious.
In India, SMS marketing isn’t just about catchy offers and shortcodes. It’s a dance with compliance, led by TRAI’s DLT system. And if your steps are even slightly off-beat, you’ll be out of the game before you even know what hit you.
Let’s take a closer look at the real legal risks lurking behind every SMS campaign — and how you can protect your brand from a crash landing.
The DLT Mandate: No Registration, No Delivery
You can’t run SMS campaigns in India without registering on a DLT (Distributed Ledger Technology) platform. Period.
TRAI mandates that every business using SMS for marketing, transactional, or service-related communication must be registered on a telecom operator's DLT portal — like Airtel, Vodafone, or Jio. This includes registering your entity name, headers (sender IDs), and message templates.
If you’re not registered, your messages don’t just underperform — they won’t get delivered at all. Worse, if you try to work around the system using unregistered routes or shady vendors, you risk penalties, message blocking, and in some cases, total disconnection from telecom partners.
Consent Isn’t Optional — It’s the Law
Imagine receiving an SMS from a brand you’ve never heard of. You didn’t sign up. You didn’t agree to it. You’d probably hit delete — or worse, report it.
Now imagine hundreds of users doing that to your brand.
TRAI’s regulations are crystal clear: you must have explicit user consent before sending promotional SMS. That means clear opt-in mechanisms — like checkboxes, digital forms, or written approvals — that document a user’s agreement to receive messages from you.
If you skip this step, and a user complains, your account can be blocked on the DLT platform — even if it’s your first offense.
Template Trouble: When Messages Don’t Match
Think you can tweak your SMS content after getting your template approved? Think again.
All promotional and service-related messages need to be pre-approved templates on the DLT platform. The system uses strict text-matching algorithms. Even a small word change, an emoji addition, or spacing issue can flag the message as non-compliant — and stop it from being delivered.
Brands often underestimate this. But the truth is, template mismatch is one of the most common reasons messages fail — or worse, trigger red flags from telcos.
The Temptation of Transactional Routes — And Why to Avoid It
Let’s get this straight. Transactional routes are for transactional messages only.
Think OTPs, balance alerts, booking confirmations — not discount codes or limited-time offers. But many marketers try to bypass DND (Do Not Disturb) filters by using transactional routes for promotions.
Don’t do it. It might seem like a clever hack, but it’s a serious violation. If caught, you could face immediate route bans, hefty fines, or even legal notices. Stick to promotional routes — and keep your campaign clean.
Timing Matters: The 10-to-9 Rule
Did you know that promotional SMS in India can legally be sent only between 10 AM and 9 PM?
This rule exists to protect users from late-night spamming. Sending messages outside this time window, even by mistake, is considered a violation. And if you’re using bulk tools without proper scheduling features, you might not even realize you’re breaking the rule — until the complaints start pouring in.
The fix is simple: always schedule messages within the permissible window. It’s not just smart — it’s the law.
No Opt-Out = Big Problem
Every promotional SMS must include an opt-out mechanism, usually something like “Reply STOP to unsubscribe.”
If you don’t include it, you’re not only giving users no way to escape your messages — you’re also breaking a major TRAI rule. And when users get frustrated, they report. When they report, your sender ID gets flagged. And once flagged, getting back in the game is painfully slow.
Always make it easy to say no — it builds trust and keeps you compliant.
Data Privacy: Not Just a Buzzword Anymore
Thanks to India’s Digital Personal Data Protection (DPDP) Act, businesses are now under stricter scrutiny when it comes to data handling.
That means if you're using scraped numbers, purchased databases, or sharing user data with unauthorized third parties — you're treading dangerous waters. These aren’t just telecom violations anymore. They’re data privacy violations, and they come with serious legal consequences.
Collect user data legally. Store it securely. And use it responsibly. Anything less could cost you far more than a missed campaign.
Proof of Compliance Isn’t Optional — It’s Essential
At any time, telecom providers or regulators can ask you for proof — DLT registration certificates, consent logs, message delivery reports, or approved templates.
If you can’t produce them? That’s a red flag. And when compliance officers see red flags, they don’t wait long to pull the plug.
Always maintain a compliance folder. Keep your documents organized and accessible. This is your shield when audits or disputes arise.
