Customize A/B Splits in Flow Builder

   Tip: Select any of the images or GIFs in this article for a closer look.

We are so excited to share that you can now customize the size of your A/B splits in campaign flows!

What's Changing and When

Starting 2/11/22, you can now configure the A/B split in campaign flows. Previously, the split was an automation 50/50 split.

Here's how this change benefits you:

  • Have more control over how the split is distributed between two different messages.
  • Test out messages with a small percent of the intended subscribers and still view performance metrics once the campaign sends.

Customize A/B Splits

  1. Select the A/B Split component in the campaign flow.
  2. Adjust the A or percent to reflect your preferred split. Postcript will automatically calculate and enter the percentage for the second split group.
  3. Select Save.
