I need to create a control group inside Marketing Cloud. A control group would be a subgroup of a data extension to whom I would not send campaign information. Example: If I had a DE with 500 campaign members, I could have 100 members as a control group and 400 as "not control group".
Then I would measure the 400 members success against the 100 members success to have an overview of campaign success. Is there any form to measure this inside SFMC?
And case have a sync between Sales and SFMC, is there a form to measure?
