The simplest way to bulk add emails to the Global Unsubscribe List when using Vuture Lists is to provide those to Vuture in Excel or CSV format. We only require a list of email addresses since is this the field we use for suppression.

We will then use our APIs to add them to your Global Unsubscribe List using the process described in this helpdesk article choosing the global unsuppression option.

Note that you must have the system configuration "Admin.System.Emails.Unsubscribe Whole System" enabled to ensure that the Global Suppression List is checked when uploading new CSV files.
