You may notice different metrics when comparing a campaign in the Campaign Performance and Campaign Delivery reports to the same campaign in the Community Overview report. The reason for this is that both the Campaign Performance and Campaign Delivery reports are campaign-specific and only show metrics for the original campaign. However, the Community Overview report also includes metrics for anywhere the original campaign was embedded, such as a newsletter and drip workflow. This means that you will probably see higher numbers in the Community Overview report, as opposed to the Campaign Performance and Campaign Delivery reports.
