Journeys Experiments changelog cover

Experiments bring A/B testing to Journeys. Add an experiment to any send node and run 2 to 10 template variants on a single send, without a separate testing tool or glue code.

  • Not just A/B: 2 to 10 weighted variants on one send node.
  • Deterministic, sticky bucketing, so each recipient keeps the same variant across sends.
  • Per-variant metrics (sent, delivered, opened, clicked) in the Results and Metrics views.
  • Promote the variant you want when you're ready, and build it in the UI or through the API.
