Benefits
Small changes to subject lines can double your open rate. Test variations and let the data decide.

Set your test criteria and sample size. We pick the winner and send it to the rest of your list automatically.
We calculate statistical significance so you know when results are real, not random noise.
How it works
Write two or more versions of your email. Test subject lines, content, CTAs, or anything else.
Choose your sample size and winning metric. Usually 10-20% of your list for the test, opens or clicks to pick the winner.
We split your test audience evenly across variations and send them simultaneously.
After your test period, we automatically send the winning version to the rest of your list.
