What to watch

  • Further TRAI announcements on sender blacklisting, telecom-resource disconnections, penalties or traceability requirements.
  • Rising SMS delivery failures, template rejections, DLT header blocks or sudden declines in reachable campaign audiences.
  • Increased customer complaints, DND-related disputes or telecom-provider notices tied to a retailer, agency, franchisee or calling vendor.
  • Major telecom operators tightening enterprise onboarding, consent proof requirements or promotional-message filtering.
  • Enforcement actions involving prominent retail, e-commerce, fintech, delivery or loyalty-program brands.
  • Growth in WhatsApp, RCS and app-push promotional volumes as brands redirect communications budgets away from bulk SMS and calls.
  • Create a unified consent ledger linking mobile number, consent purpose, timestamp, source, DND status, header/template and withdrawal history.
  • Pause or quarantine promotional lists that cannot demonstrate explicit, auditable consent, especially data acquired through stores, contests, affiliates, marketplaces and lead vendors.
  • Separate transactional, service and promotional communications operationally; review whether delivery, payment, warranty and loyalty messages contain promotional content.
  • Audit all SMS and calling vendors, franchisees, store teams and outsourced call centers for TRAI registration, approved headers, template usage, opt-out handling and data-sharing controls.
  • Shift high-frequency offer communication toward first-party loyalty enrollment, app push, email and opted-in WhatsApp, while measuring incremental revenue rather than gross sends.
  • Build delivery-rate, complaint-rate, opt-out-rate and blocked-header dashboards by campaign, vendor, region and customer-acquisition source.
  • Prepare festive-season fallback plans using owned audiences and in-store activation in case SMS routes, sender IDs or vendor accounts are suspended.
