Booking Dropoff Recovery Experiment

"An A/B/C/D coupon-depth experiment on Android first-time bookers who dropped at booking details — CleverTap cohort, mobile-level dedupe, Gupshup WhatsApp dispatch on an n8n cron. The 20% coupon variant won with a +2pp conversion lift over control, at under ₹200 per incremental booking."

Executive Summary

Users who reach booking details and vanish are the warmest leads a travel app has. I built the full recovery pipeline: cohort from CleverTap booking_details events, ABRS new-user check, mobile-level dedupe, coupon-depth bucketing (10% / 15% / 20% / control), personalized WhatsApp recovery messages 20–30 minutes after drop, dispatched via Gupshup on an n8n cron. Phase 2 went live with 17K+ real sends.

Key Outcomes

  • 20% coupon variant won — roughly +2pp conversion lift over control.
  • Under ₹200 per incremental booking — a clearly profitable recovery loop.
  • 17K+ real sends in Phase 2 with clean cohort hygiene (new-user check + dedupe).
  • Winning coupon strategy now feeds the always-on dropoff recovery flow.
