You will find the New list button under Settings > Account settings > Lists.
This feature allows you to create a new list and to complete its setup.
First of all, insert the List name and the Company, used internally to identify the business that the List is associated with (e.g. if you are an advertisement agency and you are managing the mailings of several clients).
Th following section is divided in its turn into 5 sub-areas that allow to completely customize your messages. Click here for a comprehensive description of each one of them.
Before proceeding to set all the parameters, you have a very useful tool that allows you to copy look and settings (such as message header, footer, default messages, e-mail notifications, preference center, etc.) from another existing list: "Copy settings from list", just select the list from which you want to copy the settings from the drop-down menu and click "Save".
