How doI search for all opted out email addresses?
All you need to do is go under the “Marketing” section of the menu and then go to “Reports”.
Once there, look for the report called “Unsubscribe Report”.
I have added a screenshot I made below OR you can go to the help article on this topic: https://classic-infusionsoft.knowledgeowl.com/help/unsubscribe-report
Let me know if you have any questions!
