The challenge
A Mumbai developer had 12,000 closed-lost contacts across two completed projects and one new launch sitting cold in HubSpot. Manual reactivation had been tried twice and abandoned because it ate sales-team bandwidth. The list represented two years of ad spend with zero ongoing return.
How we deployed
- Ran DND scrub and WhatsApp Business consent check across the full 12,000 contacts.
- Segmented by original budget band, project preference and reason-lost tag.
- Sent tailored WhatsApp openers per segment — new launch nearby, price drop, ready possession.
- Followed non-engaged contacts with a single SMS at day 7.
- Routed any reply within 90 seconds to a human relationship manager with full context.
- Retired confirmed-dead contacts so future runs cost less.
What changed
- 11.4% of the 12,000-contact list engaged in a real conversation.
- 127 booked site visits in the first 45 days.
- Rs 4.7 crore in net-new bookings closed inside 75 days.
- First booking closed on day 9 — a buyer who had been silent for 14 months.
- Total campaign cost was under 2% of the recovered revenue.
"We had written that list off as dead money. It funded our entire Q3 marketing budget and then some."
