What Is A/B Testing?
A/B testing (or split testing) is a method of comparing two versions of an email, landing page, or other marketing asset to determine which performs better. One version is shown to half the audience and the other to the remaining half, with results measured by metrics like open rate, click rate, or conversions.
Also known as: split testing, multivariate testing
Why Does A/B Testing Matter?
A/B testing removes guesswork from marketing decisions. Testing subject lines alone can improve open rates by 10-20%. Look for email marketing platforms that support automated A/B testing with statistical significance calculations.
