Test Ideas by Splitting Contacts Randomly with the Split Action

The Split action sends contacts down different paths in percentages you choose. It is the simplest way to A/B test emails, texts or follow-up timing.

How it works

• Distribution Type: Random Split is the only option.
• Paths: up to 5, each with a name and a percentage.
• The percentages must total exactly 100 or the action cannot be saved. A path set to 0 percent receives no one.
• Once a contact is assigned to a path, they always return to that same path if they re-enter the split.

Set it up

1. Click +, then choose Internal > Split.
2. Select Random Split.
3. Add paths, name them such as "Headline A", and set each percentage.
4. Check that the total is 100 percent, then save.
5. Build the steps under each path and publish.

Reading the results

Open the action's Statistics tab, or turn on Stats View, to see how many contacts entered each path.

Examples

• A/B test: 50 percent receive an email with headline A and 50 percent receive headline B.
• Lead routing: 75 percent to an experienced rep and 25 percent to a trainee.
• Timing test: half of contacts get the follow-up the next morning, and half after two days.

When to use If/Else instead

Split is purely random. If you want to separate contacts by a rule, such as order size or tag, use If/Else.

Changing a live split

Edits apply to contacts who enter afterward, not to those already assigned.

Good to know: Change only one thing per test, such as the headline, so you can trust which version performed better.
