Not all SMS is the same. Transactional messages are expected service communications: OTPs, booking confirmations, payment alerts, shipping updates. Promotional messages are marketing: offers, launches, festival campaigns, win-backs.
Blurring the two creates operational and trust problems. Customers who receive offers in the same pattern as OTPs learn to ignore everything. Teams that treat every SMS as a blast miss the reliability requirements of transactional journeys.
In India, sender and template discipline matters. Businesses should plan promotional and transactional journeys separately — including content ownership, timing rules, and reporting. DLT/TRAI realities are part of implementation planning, not an afterthought.
Design tip: transactional SMS should be short, unambiguous, and tied to a user action. Promotional SMS should be audience-scoped, offer-clear, and ready for a follow-up channel when someone replies or clicks through.
SMS works best as part of a stack. Failed deliveries or high-intent replies can trigger WhatsApp or voice follow-up. Calling teams should see SMS outcomes in CRM so conversations stay coherent.
If your current SMS program is one spreadsheet and one sender ID for everything, start by splitting journeys. Clarity beats volume. Property teams that send visit reminders after an AI call should also read how AI voice agents convert real estate leads.
