When creating your Custom Dashboards, you might want to take a look at your who is no longer interested in receiving your content. To add this component, go to Insights > New Dashboard or select a previously created Custom Dashboard > Add Component > Subscriber Opt-Outs. For more info on creating Custom Dashboards check out this help desk article!
We hope you don't have to access this card too often, but the Subscriber Opt-Outs component shows your subscribers who have chosen to no longer receive your content via automated newsletters or email campaigns. Feel free to sort and order the opt-outs and export them as a CSV file also.
Remember: You can also filter your subscribers by selecting the orange filter button in the top right corner of the component.
