Sometimes mistakes happen and you need to cancel a scheduled experiment. We'll go over the ways you can cancel your experiment below.
The method you should use to cancel will depend on what stage of deployment your experiment has made it to already. Ensure you read the following and choose your cancellation methodology carefully to avoid unintended deployments or double deployments.
Your experiment is scheduled and split tests have not gone out
Navigate to the Jacquard App in Salesforce and find the experiment you want to unschedule. Open the experiment and then the integration drawer on the right side of the screen, within which you can click the Cancel button.
This will reset everything in Salesforce Marketing Cloud so you can make your changes and reschedule your experiment.
Your split test email has been sent and you want to cancel the final email
In this case, do not reschedule your experiment from the Jacquard App. If you do, your splits will be resent and everyone in your test audience will end up seeing the email twice.
Instead, follow the steps below:
Locate the final email in the Tracking folder under Email Studio > Tracking > Sends > My Tracking. You'll know it's the final email because the Name will be the same as your split test deployment but the AMPscript in the subject line will be referencing the Winning Subject Line.
Click on the email name.
Click on Cancel Send.
When you're ready to reschedule your final deployment, you'll want to manually send the email from Salesforce Marketing Cloud. Make sure you properly suppress your split testing list from your final deployment if you choose to make a new user-initiated email.
Your split test has been sent and your final email is mid-deployment
Generally, the only opportunity to cancel a final send already in progress is if your experiment had send throttling enabled or if you are sending to a very large list that takes awhile to deploy.
You will have to look in the Email Studio > Tracking > Sends > My Tracking to locate your send. If any emails have not been sent, the status of the email will be In Process. If your email is in this state, you can pause or cancel the send as you normally would in Salesforce Marketing Cloud with the Pause Send or Cancel Send button.
If you are going to resend your email, you will need to use native Salesforce Marketing Cloud tools to determine who has already received your email so you can suppress those subscribers from your resend.
