I need a campaign post-mortem. Be direct and honest. Do not soften failures or inflate successes. If something underperformed, say so clearly and suggest why.

**Campaign:** [name and brief description]
**Duration:** [start date — end date]
**Budget:** [total spend and allocation by channel if available]

**Goals set before launch:**
[List each goal with its target metric]
- Goal 1: [e.g., Generate 500 leads at <$20 CPL]
- Goal 2: [e.g., Drive 50K landing page visits]
- Goal 3: [e.g., Achieve 3.5x ROAS on paid spend]

**Actual results:**
[Paste performance data — channel breakdowns, conversion data, revenue, engagement metrics]

**Qualitative observations:**
[Things the data doesn't capture — customer feedback, team observations, operational issues, external factors]

Produce a post-mortem with these sections:
1. **Verdict** (2 sentences: did the campaign meet its goals? Overall assessment.)
2. **Goals vs. Results** (table: goal, target, actual, met/missed, gap)
3. **What Worked** (2-3 items with data + explanation of WHY)
4. **What Didn't Work** (2-3 items with data + honest diagnosis)
5. **What We'd Do Differently** (3 specific, actionable changes — not "optimize targeting" but "narrow audience from broad interest to lookalike based on Q1 purchasers")
6. **Action Items** (owner + deadline format if applicable)

Reference only data I've provided. Flag any gaps as "DATA NOT PROVIDED."
