Measure the impact of your messages with control groups 👥 ⚗️

Control group testing withholds your message from half the audience, so you can measure the difference in behavior between the control group and those who receive the message. It’s a powerful, data-driven way to validate message performance, set benchmarks, and eliminate low-impact messages. Control groups are available on our Messages Premium plan.
