I pushed out an email yesterday morning and went into the smart campaign to check out the results. I looked at the "Email" tab, to see an overview (# sent, #delivered, % delivered, etc) and then navigated to the "results" tab to see each individual person that received the email. I noticed that when I counted up each individual with an activity type of "email delivered" the # did not match the "#delivered" in the Email tab. Can anyone help explain why?
