Can I export my subscriber data to Excel?

Yes, it is just as easy to export your data as it is to import it.

On the page Subscribers → Browse, you will see an Excel icon under the table of your active subscribers. If you click this, you list is exported to an excel file:

You can see the status of the export in the side bar. When the entire list is exported, the export is ready and you can download it by clicking the relevant list. The Excel file you download will have three tabs: one for active subscribers, one for those who have unsubscribed, and one for cleared-out subscribers.
