Create a structured message experimentation plan across [Channels] to validate [Hypotheses] with a minimum [SampleSize] audience and a primary [PrimaryKPI] during [TestWindow]. Define variants (hooks, benefits, proofs), targeting, and sequencing rules.
Output format:
Test charter (objective, hypothesis, success metric, guardrails);
Experiment matrix (Variant, Channel, Audience, Sample, Expected Lift, Risk);
Pre-registration summary;
Analysis template with statistical test choice and decision rules;
Roll-out & deprecation plan.
Ensure learnings are attributable and actionable across paid/owned/earned media.
