Analyze the performance data from our influencer campaign and give me actionable insights.

**Campaign overview:**
- Brand: [name]
- Product: [what was being promoted]
- Campaign goal: [awareness / traffic / sales]
- Total budget: [amount]
- Campaign dates: [start — end]

**Per-creator performance data:**

| Creator | Platform | Format | Fee | Impressions | Likes | Comments | Shares | Saves | Clicks | Conversions |
|---------|----------|--------|-----|-------------|-------|----------|--------|-------|--------|-------------|
| [Name1] | Instagram | Reel | $X | X | X | X | X | X | X | X |
| [Name2] | TikTok | Video | $X | X | X | X | X | X | X | X |
| [add all creators] |

**Analyze and provide:**
1. **Creator ranking** by cost-per-engagement (CPE) and cost-per-click (CPC). Who delivered the most value per dollar spent?
2. **Format analysis** — which content formats drove the best engagement? Best clicks? Best conversions?
3. **Messaging insights** — if I paste the top 3 and bottom 3 performing captions/scripts below, identify what messaging patterns drove results. [PASTE TOP AND BOTTOM CONTENT IF AVAILABLE]
4. **Re-engagement recommendations** — which creators should we work with again? Which should we drop? Which should we give a second chance with adjusted format/messaging?
5. **Next campaign brief** — based on these results, what should the next campaign emphasize? Which formats, messaging angles, and creator tiers?

Be specific. "Creator A outperformed" isn't useful. "Creator A delivered 3.2x the engagement per dollar compared to the campaign average, primarily driven by her Reel format where comment rate was 4x the static post average" is useful.
