You wrote the message, double-checked the spelling, and submitted it for approval. A day later, the status reads rejected, often with a reason that tells you almost nothing. If that sounds familiar, you’re in good company. Almost every business that sends commercial SMS in India has been through it. The good news is that most DLT template rejections come from a small set of repeat mistakes, and once you know them, they’re surprisingly easy to avoid.
A Quick Refresher on Why Templates Exist
In India, commercial SMS runs through the DLT (Distributed Ledger Technology) framework set up under TRAI’s telecom commercial communications regulations. The idea is simple: every type of message you send needs an approved template, registered against your sender ID. Templates generally fall into categories such as promotional, transactional, service implicit, service explicit, and OTP, and the right one depends on the purpose of the message. Pick the wrong category, and trouble tends to follow.
The Brand Name Problem
One of the most common reasons for rejection is branding. Templates are often turned down when the brand name is missing from the fixed text, or when the name in the message doesn’t match the name on the registered DLT entity. It sounds trivial, but reviewers check it closely. Put your brand name in the fixed part of the message, not inside a variable, and make sure it matches your registration documents exactly.
Mixed Intent Confuses Reviewers
Another frequent trap is trying to do two jobs in one message. A classic example is an OTP that also carries a discount offer. To a reviewer, that’s a transactional message wearing a promotional hat, and it usually gets rejected. The fix is easy: keep one purpose per template. If you want to send an offer, create a separate promotional template with its own category and opt-out wording.
Variables Are Where Most Templates Go Wrong
Variables, the placeholders for things like names, amounts, and order numbers, cause a surprising number of rejections. The placeholder has to be typed in exactly the expected format, and templates tend to fail when they use too many variables, place two of them side by side, or stuff too much into a single one. Keep the count low, separate them with fixed words, and remember that each value you send later should stay within the length limit. Overly long templates are another quiet culprit, so check your character and segment count before you submit.
Links, Headers, and Language
Three technical details trip people up regularly. First, links: any URL in your message should be whitelisted against your sender ID before you submit, including short-link domains. Operators have been blocking unwhitelisted links, so this one can’t be skipped. Second, headers: the header you use should be registered for the same category as the message, and recent TRAI changes mean headers can carry category suffixes. Third, regional languages: if your message is in Hindi or another Indian language, it should be submitted as Unicode, not pasted in as plain text.
Approved Doesn’t Always Mean Delivered
Here’s a point many people miss. Getting a template approved isn’t the finish line. Messages can still fail to deliver if what you send differs from the approved text by even a single space or punctuation mark. Other common causes include using the wrong template ID, variable values that run too long, a missing link in the sender-to-template chain, or promotional messages sent to DND numbers or outside permitted hours. If delivery drops after approval, compare the sent message with the template character by character before blaming the network.
Resubmitting Without Starting From Scratch
Approved templates generally can’t be edited, so any change means creating a new template and switching to its ID. Every rejection also restarts the review, which is why getting it right the first time matters. Before you submit, run a simple checklist: brand name in the fixed text, one purpose per message, correct category and header, clean variables, whitelisted links, and the right opt-out wording for promotional messages. For a full walkthrough of the common reasons and their fixes, this detailed DLT template rejection guide covers each one step by step.
Get a Second Pair of Eyes
A quick review before submission can save days of back-and-forth. Teams at MetaReach Marketing work with businesses on DLT registration support and template preparation alongside SMS, voice, and WhatsApp services. Whoever you work with, regulations and operator rules do change, so always confirm the current requirements with TRAI and your telecom operator before you rely on any checklist, including this one.
