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

• Hypothesis – statement of expected lift + rationale.

• Variable Selection – hook, CTA, body copy, offer framing, proof element.

• Segmentation – define audience splits and holdouts.

• Metrics – primary KPI + guardrails (opens, CTR, CVR, CPL, unsub, spam).

• 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.
