The Settings section in your admin console that gives you the tools to custom the console itself according to your needs.
It is divided into two sections:
List settings
This sections deals with List-specific settings, i.e. settings that are only valid for the List you are in. As defined in the Glossary, a List in the MailUp admin console is an independent set of messages, settings, statistics, filters, events, groups, subscribers, unsubscribers, etc. You can create multiple Lists in your admin console.
List in the MailUp console is not to be confused with a Group which is a subset of a List.
Account settings
The Account settings section allows you configure every feature of your admin console which is not list-specific, but related to the admin console as a whole, or that helps you manage more easily your every-day work inside your admin console.
