A/B testing (split testing)

Is there a way to see whether your cold email could be better? Yes, there is. Try A/B testing. It is a popular testing method used among outreach specialists to find out which element works best, be it a subject line, CTA, etc. To get clear results, outreach specialists compare as few as two alternative versions of one element, and choose the one that performs better. A/B testing is called split testing by some people. Why? Because you split the group you’ll conduct the test on into two equal groups. One group gets version A and the other, version B of the element you’re testing.
