On the Subscriber Details page you can find and manage your subscriber profiles. You can access the page by clicking on the name of the subscriber in the list of subscribers at the bottom of your Subscriber page. You can then view or edit the details of this specific subscriber.
If your subscriber has uploaded a profile picture on Gravatar, you will be able to see it here.
You will also be able to edit the first-name and email-address fields for each subscriber, as well as any custom Subscriber Fields you have created.
This is also where you can add tags to individual subscribers, making it much easier to filter through your customers and create targeted segments for your email campaigns.
Finally, under Subscriber Details, you are also able to manually set a customer's subscription status to “confirmed”, “unsubscribed” or “blocked”.
