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.
