Test two variants on a slice of your audience and let the numbers decide — the winner is sent to everyone else automatically. Test whole sequences with percentage splits inside automations.
Send variant A and variant B to a test sample; the rest of the audience waits for the winner.
Judge the winner by open rate, click rate, or reply rate — replies matter for cold outreach.
After the test window closes, the winning variant goes to everyone else — no manual step.
Drop a split node in any automation to route a percentage of contacts down each branch.
Each contact lands in the same variant every time — results stay clean and repeatable.
Opens, clicks, and replies broken down by variant, in the dashboard and the API.
Duplicate a campaign, tweak the subject line, and let the winner ship itself.
