Every Newsletter contains Editions -- the email sent to your subscribers list. When you’d like to send your Newsletter, you will add articles to a new Edition.
Click on the Name of your Newsletter and click Create Edition.
Each Edition automatically includes details from your Newsletter Settings & Template (like sections, colors, images, and copy). Adding, removing or editing content of one Edition does not affect your Newsletter Settings & Template or future Editions of your Newsletter.
Proceed to the Compose step to edit content, add and organize articles in Sections and preview your Edition.
