Build an email in ONTRAmail or our HTML email editor. Save it and name it "Newsletter: Template". This becomes your template.
When you're ready to create your monthly newsletter, select the checkbox next to your "Newsletter: Template" and select the Copy button from the Actions drawer. Now you can edit the name to reflect your monthly newsletter and keep the original one as your template.
