+## 🔄 POST-COMPLETION (triggered emails, not campaigns)
+
+### 18. Order Completion Email — Exit Survey + Referral + Review
+Triggered when order status changes to "delivered" / "completed". Not a campaign — a transactional email per order.
+
+**Email flow:**
+1. "Your [service] is complete!" — delivery confirmation with documents attached
+2. 24 hours later: Exit survey (3 questions max)
+   - How would you rate your experience? (1-5 stars)
+   - What could we do better? (free text)
+   - Would you recommend us? (Yes/No)
+3. If rating >= 4: Ask for Google review with direct link
+   - "Leave us a review on Google — it takes 30 seconds and helps other truckers find us"
+   - Direct link to Google Business review page (skips the search step)
+4. Referral program pitch:
+   - "Know another trucker who needs help with compliance?"
+   - "Send them your referral link and earn $25 credit for each order they place"
+   - Unique referral code per customer (e.g. REF-MARKADAMS)
+   - Credit applied to their next order or paid out
+
+**Implementation:**
+- Exit survey: store in DB, flag low ratings for admin follow-up via Telegram
+- Google review: link format https://g.page/r/YOUR_PLACE_ID/review
+- Referral: generate unique code per customer, track via discount_code system
+- Timing: send 24h after completion (not immediately — let them receive documents first)
+
+**Revenue impact:**
+- Reviews build trust → higher conversion on compliance checker
+- Referrals: truckers know truckers — word of mouth is huge in this industry
+- Survey feedback improves retention
