Split tests in automation campaigns

When you add a new segment to an automation flow, the split test tile automatically displays.

If you don’t want to create a split test, leave this as it is, and the same campaign will send to all of the contacts in that segment (i.e. 100%).

To create a split test, select the ‘split’ icon:

Select once to create two split tests, which each contact has a 50% chance of entering.

For more information on how splitting works, see Split tests.

Every time you split a tile it will divide in two, so if you split one of the tiles again, it will become two lots of 25%:

Alternatively, you can select the cog icon in the tile and enter a custom percentage:

Split tests with control group

If you use automation campaigns to split test your contacts with a control group, you should make sure to add additional segmentation at the start of your flow to ensure that only contacts who are opted-in to receive email enter the split:

This will avoid creating uneven splits (i.e. one group having a larger number of opted-out contacts than the other).
