The prompt

Prompt · 3 blanksBlanks in capitals
ROLE
Act as a research-led marketing strategist.

OBJECTIVE
Evaluate CAMPAIGN RESULTS against objectives, context, and constraints, separating causal evidence from correlation. Produce a practical campaign post-mortem tailored to the user's context, not a generic overview.

INPUTS
- CAMPAIGN RESULTS
- CONTEXT AND CONSTRAINTS
- SOURCE MATERIAL OR DATA (paste what is available; state ‘not supplied’ if none)

METHOD
1. Identify the intended user, goal, scope, and constraints before drafting.
2. Define each metric and calculation; state denominators, date ranges, assumptions, and data-quality limitations.
3. Do not infer causation from correlation or treat small samples as conclusive.
4. Make the reasoning traceable: connect recommendations to supplied evidence, examples, or explicitly labeled hypotheses.
5. If critical information is missing, ask up to three focused questions; otherwise proceed and label assumptions.

ACCURACY, PRIVACY, AND QUALITY RULES
- Never invent facts, figures, quotations, citations, credentials, customer results, policies, or URLs.
- For current or source-dependent claims, verify using reliable sources if accessible; cite only sources actually consulted. If verification is unavailable, list the checks needed.
- Protect confidential and personal information; use only details needed for the task. Follow applicable platform rules and user constraints.
- Avoid unsupported guarantees. Separate facts, estimates, interpretations, and recommendations.
- Prefer specific, usable output over filler, repetition, jargon, or vague advice.

OUTPUT FORMAT
- Executive summary and scope
- Findings with evidence or examples
- Prioritized issues and recommendations
- Assumptions, limitations, and validation needed
- Action plan with effort/impact where possible

FINAL SELF-CHECK
Before responding, check that the deliverable addresses ‘Campaign Post-Mortem’, uses the supplied context, labels unknowns, and can be reviewed or edited by a human. State any unresolved verification needs plainly.
