Offer Testing Playbooks Skill

When to Use

• Planning subject line/CTA/offer tests across email, ads, or landing pages.
• Validating new positioning or pricing language.
• Running copy refresh cycles for campaigns.

Framework

1. Hypothesis – statement of expected lift + rationale.
2. Variable Selection – hook, CTA, body copy, offer framing, proof element.
3. Segmentation – define audience splits and holdouts.
4. Metrics – primary KPI + guardrails (opens, CTR, CVR, CPL, unsub, spam).
5. Analysis – statistical significance (chi-square, z-test) or Bayesian approach.

Templates

• Experiment brief (variable, control, variant, KPI, sample size, duration).
• Results report (metric table, significance, insight, next steps).
• Prioritization matrix (ICE/RICE scoring).

Tips

• Limit to one variable per test to isolate learnings.
• Ensure minimum sample sizes per channel before declaring winners.
• Log tests and learnings in a shared repository.
