Stop an Experiment or its Winner

Sometimes, you may want to stop an experiment that's already running, such as when you want to declare a winning email campaign before the experiment completes its full duration. For example, the experiment report may show real-time statistics that clearly identify a strong leading variation. If you believe that this campaign will continue to lead, you may want to end the experiment early. After you stop the experiment, you choose the winner and schedule it. We'll then start sending the winning email campaign. If you choose to stop this process, you may want to view the experiment report, which shows experiment statistics to the time when it was stopped.

If you stop an experiment before we start sending, you can edit or reschedule the experiment. In general, you only stop an experiment that is being sent or running because you don't want to run it after all or, as in the previous example, you want to manually choose a winner.

If you stop a winning variation before it we start to send, you can reschedule it. You can't stop the sending of a winning variation once it starts.
