The Challenge

Student acquisition for competitive exam coaching has become increasingly expensive. Google Ads CPL for NEET admissions in Tamil Nadu runs ₹300–₹900 per lead. Meta Ads are ₹250–₹700. Education portals charge ₹250–₹600 per enquiry.

The institute had a database of over 4.5 lakh previous NEET aspirants — students who had already demonstrated serious intent by attempting NEET at least once. The question was how to reach them at scale without burning budget on per-click advertising costs.

Scalify Labs was brought in to execute a large-scale OBD (Outbound Dialer) voice campaign targeting this existing database for NEET Repeater Batch 2027 admissions.

Why OBD Calling?

Instead of asking counselors to manually call lakhs of students, Scalify Labs deployed an automated Outbound Dialer solution that worked in parallel around the clock.

The platform automatically:

• Dialled every number in the database
• Played a professionally recorded admission message in Tamil and English
• Identified interested responses through keypress/voice input
• Transferred hot leads to counselors in real time
• Generated campaign reports per calling session

Counselors received only students who had expressed active interest — no time wasted on busy lines, no-answers, or disinterested contacts.

Pilot Phase Results

The campaign launched with a controlled pilot to validate script, timing, and qualification logic before scaling.

Metric	Value
Student Database	75,635
Calls Dialled	56,993
Connected Calls	14,247
Qualified Leads	33
Call Cost	₹0.22 per call
Campaign Spend	₹3,134
Cost Per Lead	₹94.98

Leads at under ₹100 per qualified enquiry in the pilot confirmed the model worked. The institute approved scale-up immediately.

Scaling to 3.5 Lakh Calls

Based on the pilot results, the campaign expanded to over 3.5 lakh OBD calls across multiple phases. Each subsequent phase incorporated improvements:

• Better audience segmentation (by geography, previous attempt score range, stream)
• Optimized calling windows (weekday evenings 6–9 PM, Saturday mornings)
• Regional language voice scripts refined for Tamil Nadu aspirants
• Improved lead qualification logic (keypress 1 for callback, keypress 2 for fee details)
• Multiple follow-up rounds for non-connected numbers

These iterations reduced the effective acquisition cost from ₹94.98 (pilot) to approximately ₹80 per qualified lead at full scale.

Why This Campaign Worked

High-quality, intent-verified database — previous NEET aspirants, not cold contacts. These students had already invested a year preparing for NEET; the repeater batch message landed in relevant context. Regional language recording — Tamil-language primary message with English fallback. Students answered and listened because it felt addressed to them, not generic. Optimized calling schedule — Evenings and weekend mornings, when students were available and not in classes. Connection rates were 40%+ above industry average. Automated lead filtering — Counselors received only interested students. No time spent on unanswered calls, no morale drain from cold outreach. Immediate callback logic — Hot leads (keypress 1) were transferred to counselors within 60 seconds. Warm leads received a scheduled callback the same day. Continuous script optimization — Each phase used A/B tested voice recordings. Highest-performing scripts were scaled; underperformers were retired.

Counselor Productivity Impact

Before OBD: A counselor manually dialling from a list could complete 60–80 calls per day, reaching perhaps 20–25 actual students, generating 2–4 interested callbacks.

After OBD: The same counselor received 25–35 pre-qualified, actively interested leads per day — students who had already expressed intent. Counselor conversion rates from interested-to-enrolled improved because the conversation started from a warmer baseline.
