How do I restore my Mailing List from a backup?
From Bravenet Wiki
1. Log into your Bravenet account
2. Click on the Mailing List Service tab
3. Click on the link "Manage Subscribers"
4. Click on the button "Import" to import a list of email addresses. (Limited to 500 subscribers/lines per import)
If your list is relatively large, this may take a while.
