Steps
- Split one audience into equal lists (for example List A and List B, ~same size).
- Create Campaign A → List A and Campaign B → List B.
- Keep every setting the same except one variable (opening line, CTA, tone, or personalization).
- Launch both at the same time.
- Compare reply rate and other Overview metrics — Campaign analytics.
Tips
- Even splits and identical settings keep the test fair
- Run long enough for meaningful reply counts
- Roll the winner into future campaigns
