Above you will see the Newsletters that are scheduled in one pane followed by the Newsletter Scheduler in the other.

To schedule a Newsletter you must select one of the groups you have created from the Group: drop down.

You can then select the "Page" Newsletter you created to use. Input the Date you would like to send it and the Subject title.

The Optout checkmark when checked will provide your subscribers with a link to either optout of your newsletter or change to a different group.

Left unchecked it will allow them to optout of your newsletter but will not give them the option of selecting a different group.

Select the Email Server you have setup and click on Add Schedule to schedule your Newsletter.
