Hello @AdolfoM312. Great question. Were you looking to import a list of unsubscribes? To do this, you would want to go to My Settings (located in the top right corner of your account by clicking on the silhouette of the person), then scroll down to the section called Contact Settings, and check the box next to "Enable advanced email permissions". After you click Save, you should now be able to upload a file of unsubscribed contacts.
