Registration and consent come first
Commercial SMS in India runs through telecom-regulated registration of the sender and each message template. Your messaging provider can guide you through the current process, and you should confirm requirements with them before planning campaigns.
Send only to people who have agreed to hear from you, keep a record of how and when consent was given, and honour opt-out requests promptly.
Write messages that earn a response
Keep each message short, say who it is from, give one clear reason for sending it and one clear next step. Transactional messages such as order and appointment updates usually perform better and build more trust than repeated promotions.
Measure and connect it to the rest of your marketing
Track delivery, clicks and the enquiries or sales that follow, not only the number of messages sent. SMS works best alongside WhatsApp and email, with each channel used for what suits it, and with customer data kept in one place so people are not contacted twice.
Frequently asked questions
Do I need registration to send business SMS in India?
Yes. Business senders and message templates are registered through the telecom framework. Your SMS provider can explain the current steps for your account.
Should I use SMS or WhatsApp?
Often both. SMS reaches nearly every phone without an app, while WhatsApp supports richer conversations. The right mix depends on your audience and the type of message.
