How it works

  • 📋 Customer submits your Typeform → instant personalised welcome SMS fires via Twilio
  • 📊 Submission logged to Google Sheets with name, phone, timestamp, and nudge tracking
  • 💬 Twilio listens 24/7 for replies → marks customer as responded, stops all future nudges
  • ⏰ Scheduler runs every 6 hours → finds non-responders and sends up to 2 follow-up nudges
  • 🛑 System stops contacting anyone who replies or hits the 2-nudge limit

The three branches

Branch Trigger What it does
🟢 New Submission Typeform form submit Welcome SMS + log to Sheets
🔵 Reply Handler Incoming Twilio SMS Mark replied, stop nudges
🟡 Nudge Engine Schedule every 6hrs Nudge 1 at 24h, Nudge 2 at 48h

Why this matters

Metric Manual This workflow
⚡ Speed to lead Hours or days Under 10 seconds
🔁 Follow-up consistency Whoever remembers 100% automated
📉 Lead drop-off High — people go cold fast Nudges catch non-responders
🧠 Staff time per lead 5–15 min Zero
💸 Revenue at risk Every ignored inquiry Recovered automatically

Studies show leads contacted within 5 minutes are 9x more likely to convert. This workflow makes that the default — not the exception.
