Vedantu needed to solve two communication problems at the same time—secure access and growth engagement. On the authentication side, OTP and login alerts had to reach students instantly, but connectivity issues in low-network regions often caused delivery delays, impacting logins and trust. On the growth side, SMS was too limited for rich counselling journeys—Vedantu needed multimedia, interactive CTAs, and guided conversations to engage prospects, qualify leads faster, and move learners from enquiry to counselling with less drop-off.

Vedantu implemented a dual-channel strategy with Times Mobile, mapping each channel to what it does best. SMS was used for mission-critical authentication (OTPs and login alerts), delivering 95%+ delivery consistency with low latency—even in low-data environments. For engagement and conversion, Vedantu used WhatsApp Business API (WABA) to run richer communication journeys with videos, PDFs, class invites, quick replies, and CTA-driven flows, enabling faster lead qualification and stronger student engagement than SMS alone.

The dual-channel approach delivered measurable improvements across access and growth. Vedantu achieved a 12–15% uplift in authentication success, ~18% lower login latency, and sustained 95%+ delivery stability for critical SMS. On WhatsApp, engagement improved by 25–35%, lead qualification became 40% faster, and enquiry-to-counsellor interaction improved by 20–25%, while overall WABA communication scaled 2–3×.
