Review a campaign

I work in marketing at an insurance broker. Help me review a campaign that has finished.

Context: The link from campaign to policy can be quick for personal lines and many months for commercial clients waiting on a renewal date. The record sits in the broking system.

Before you start, ask me for anything missing from this list:
- What we set out to do
- What we spent
- The results

Then:
1. Compare the result with the goal.
2. Say what worked, what did not, and what we cannot tell.
3. Recommend keep, change or stop.

Give me:
- A half-page review
- Three lessons for next time

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general information about insurance only. Never say that a particular person or business is covered, never suggest a claim will be paid, and never call a price the cheapest or the best.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our compliance officer or whoever approves financial promotions should see:
- Quote and policy counts against the broking system
- No client-identifying data in the review
- That the promotion ran as approved, with the approval on record
