Hi there, I need to know how you create a control group in a Delivery but instead of doing a random selection, you get the Control Group from a previous campaign that was sent out? I have tried so many ways but can't get it to work...HELP
There are two options to achieve what you are asking.
Refer to the screen below how to select or apply a control group formula.
Option 1: If you have already sent the delivery one and you have opted for a random sampling in the delivery. Now you have to use Query option as mentioned in the above screen and the filter selects the recipient of delivery 1 and applies another filter where control is true which will give you same group as before.
Option 2: You can create a recipient List under list management and use List option to select control list in both deliveries.
I have tried that but it doesn't work, the reason for this is because our system was customized and we do not use recipient. We have a customer which is linked to product tables. I have asked the people who created our system to help so at this time I have to just excluded the Control group in the workflow instead of at Delivery stage.
