Snapshot: A regional solar sales business sitting on 10,000+ older leads (mix of enquiries, showroom walk-ins, and trade show captures). Leads ranged from 12 months to 36 months old.

Execution: Tiered reactivation logic:

1. Segment by lead age / postcode / property type.

2. Send hyper-personalised SMS mentioning the year of the original enquiry and new incentives (zero-deposit offers, new finance packages).

3. Offer short site-survey booking via link (15-20 minute slot) and a limited-time grant/finance window.

Results (headline): “Reactivated 10,000+ cold leads → new bookings within a week.”

• Week 1: 420+ site-survey bookings across target postcodes (~4.2% immediate booking rate).
• Week 2–4: sustained drip recovered another 1,200 interested prospects (total engaged ~16% of contacted list over 30 days).

Revenue example:

• If average project value = £8,000 and conservatively 5% of site surveys close in initial 60 days: 420 bookings × 5% = 21 installs → 21 × £8,000 = £168,000 in new sales from week 1 alone.

Why this worked:

• Large list + high-ticket product means even modest booking rates produce big revenue.
• Personalisation (address/year) made outreach feel bespoke.
• Immediate booking removes friction and improves show rate.
