Campaign Structure

  • Target: warm leads first (site form, LI replies), then cold with strict compliance
  • Cadence: call + SMS/email follow-up if permissioned
  • Windows: local time 9–11am, 2–5pm; avoid lunch

Script Skeleton

OPEN: "Hi {{first}}, this is Nova with Quantum — I'm an AI assistant. Calling to set a quick demo if useful. Bad time?"
QUALIFY: "Are you exploring automation for {{function}} this quarter?"
BOOK: "I can book 15 mins with {{owner}} — Tues 10:30 or Wed 2:00?"
CONFIRM: "Great — can I confirm your email as {{email}}?"

Slotting Logic

selectSlots(cal, owner, tz) ->
  fetch owner availability ->
  filter next 7 days within 9–5 local ->
  propose top 2 ->
  hold slot after verbal accept ->
  confirm + send ICS + reminder

Signals and Failover

  • Positive: schedule → stop sequence; create CRM meeting
  • Neutral: send recap + self-serve link; retry once
  • Negative: opt-out everywhere; write reason
  • Failover: transfer to human on confusion/hostility

QA & Metrics

  • Booked/connected, show rate, cancel/no-show, time-to-book
  • Listen scorecard: disclosure, empathy, clarity, compliance
  • Error taxonomy: AMD miss, slotting fail, timezone mismatch
