Smart List and Email Performance Report Show Different Numbers for delivered. Does anyone know why the smart list shows a smaller number than the email performance report?

I ran a smart list with the filter "delivered email," but it shows a smaller number than the email performance report for delivered. Does anyone know why this is?

Hey Katherine Creeden‌ - Check out this post: /blogs/marketowhisperer/2015/07/10/why-does-my-smart-list-count-not-match-the-email-performance-repo... That should answer it for you

But surely delivered is a reliable metric to look at in a smart list? Eh, not so much. Certain categories of soft and hard bounces only register after the delivered message. In this case, the activity log will show a Delivered activity followed by a Bounced activity. The report will register the person as delivered, but as soon as we get a bounced message, it will no longer count that email as having been delivered. This means your delivered numbers in your report could actually decline over time as we get more accurate information back from the email client.
