A/B testing in automations

Last Updated: Jul 10, 2025

A/B testing in automation helps you fine-tune your email strategy by comparing two variations of your emails to see which performs better. Whether it’s subject lines, designs, or content, testing allows you to make data-driven adjustments to improve results.

This guide will show you how to set up and analyze A/B tests seamlessly within your automated workflows.

Setup

To include an A/B test in your automation workflow, simply click to add element and select “Split”.

A/B testing block has only two paths can be added to the block settings, but cannot have a single resolution position.

In the split setup, you can define the percentage distribution for your audience.

By default, the split is set to 50/50, but you can adjust it to any other ratio. A 50/50 split works best when the goal is to test different variations equally.

However, if you’re distributing something like a discount and want it to be more random, you might opt for an uneven split, such as 40/60 or the reverse, depending on your needs.

Once the campaigns are sent and the test phase is finished, compare the reports to learn more about your audience preferences and the subject line that works best.

After the campaigns are sent and the test phase is complete, review the reports to gain insights into your audience’s preferences. The opens and clicks of each campaign will help you determine which subject line performed better.

That’s it!
