It's great to be able to see stats for how many people unsubscribed, under Marketing > Emails > Statistics. Unfortunately, this data does not match the data shown under Marketing > Emails > Campaigns > Workflow Campaigns > Click the 3 dots to the right of a workflow name > Click "View Statistics"
I'm specifically referring to the "Unsubscribe" data. Right now, the data in the "Marketing > Emails > Statistics" section could show that there were unsubscribes that occurred in the last 7 days ( specifically in workflows ), but the stats shown under "Marketing > Emails > Campaigns > Workflow Campaigns > Click the 3 dots to the right of a workflow name > Click "View Statistics" will show the number of unsubscribes as Zero.
So, unless you use LC Email ( and go to Settings > Email Services > Email Analytics ), there is no way to know who clicked on the unsubscribe link in the email that was sent via a workflow.
It would be greatly appreciated if we could easily see a list of contacts who unsubscribed, without having to create an unsubscribe workflow.
