True or false? When you conduct email A/B testing and create test groups, both groups should be a sample of your overall audience (in size and in representation of your contacts).

A/B testing works best when each test group reflects the broader audience being evaluated. Balanced sample groups reduce the chance that performance differences come from audience makeup instead of the tested email variation. In HubSpot, A/B test results compare how different versions perform against selected email metrics. Representative groups make the results more useful for deciding which version should be sent or used going forward.
