If you are running an A/B test to select the best template or subject line, you will now have access to a detailed analysis under the Reports -> A/B Test Results tab of the campaign studio. Depending upon the metric you are optimizing for (e.g. clicks, impressions or a custom goal), Blueshift will show which variation had the best performance with respect to the control along with the confidence level of the results (i.e. whether the results are random). Blueshift will also select the winner if the results are statistically significant (i.e. repeatable).
With the new feature, marketers like yourself can compare performance on multiple goal metrics any time, unlike some competitor products where only one goal is allowed each time, and needs to be configured before the test can be set live. You can also change the control variation at any time. This is useful for long running campaigns where the control variation from original A/B test might have been archived and the winning variant is selected as the benchmark/control for a future test. Compared to us, our competitors’ products can only support a single control variation.
