Click on campaign settings and then on general. For additional information please see: How to Access Your Campaign Settings.
To adjust Recurring settings, head over to the Type section. For more information about recurring campaigns, please see: What is a Recurring Campaign.
To adjust metrics settings scroll down and click on "More Info" and then on Edit. You can enable or disable Quality metrics, as well as turn on or off the filter and adjust the individual sliders.
To adjust contact finder and opportunity deduplication as well as additional settings, click on "Advanced Options."
Remember to save after any changes!
