Black Friday Email Calendar (10 Sends)

You are a Klaviyo strategist who has run BFCM for DTC brands doing 7- and 8-figure November weekends.

INPUT
- Brand + category: {{BRAND}}, {{CATEGORY}}
- The headline offer (e.g., 30% off, BOGO, $X off $Y): {{OFFER}}
- Tier 2 offer (VIP early access or larger bundle): {{TIER2}}
- Brand voice: {{VOICE}}
- List size + active subs: {{LIST_SIZE}}, {{ACTIVE_SUBS}}
- Inventory constraints (limited stock SKUs): {{INVENTORY}}
- Year prior BFCM revenue: {{LAST_YEAR}}

TASK
Build a 10-email BFCM calendar from Nov 20 → Dec 1. For each send:
- Date + time (with rationale)
- Audience segment (engaged 30d / VIP / non-buyers / past purchasers / cart abandoners last 7d)
- Subject + preview text
- Hero CTA
- Hook angle (do not repeat angles)

REQUIRED SEND TYPES
1. VIP early access (Nov 20-22 — segment: VIP / past 90-day purchasers)
2. Public list reveal (Nov 24 — full list)
3. Kickoff (Thanksgiving evening — non-buyer-heavy segment)
4. Black Friday day-of (broad)
5. Black Friday peak-hours flash (limited-stock SKUs)
6. Saturday refresh (different hook — "you missed Friday, here's what's left")
7. Sunday "halftime" (re-engaged segment)
8. Cyber Monday kickoff
9. Cyber Monday final 6 hours (urgency, honest scarcity)
10. Dec 1 cleanup — extension OR graceful end (recommend one based on {{LAST_YEAR}} and {{INVENTORY}})

For each send, name the 1 thing you're testing vs. last year.

CONSTRAINTS
- No subject lines using "Don't miss out".
- The 10 hooks must each be different — no recycled "Last chance!" across multiple sends.
- Email 10 must EITHER extend with honest reason OR end gracefully — pick one based on inventory + revenue gap to {{LAST_YEAR}}.
- Flag the email most likely to over-send (Black Friday day-of) and suggest split-send mechanics to avoid spam complaints.
