Menu > Recipients > Toolbar

To simplify working with the list, you can use the 'List Tools' toolbar.
This toolbar allows you to manage your recipients, such as remove duplicates and remove invalid mail addresses.
You can also include or exclude recipients which are on another list or copy the list to an existing or a new list. The column group on the left provides the functionality to insert, rename or remove a column. The row group beside provides the functionality to insert and remove rows.
