To choose your fonts, colors, and styles, click Edit Design at the bottom of this screen. After you create a look and feel you love, click inside this box to start adding your own content.
Any time you create a layout here, you'll be able to find it in the Saved Templates tab on the Templates step. Then, you can reuse it as-is or quickly create new, similar versions for different types of messages.
Our Email Design Reference can help you add content blocks to this template or show you how to design and code your own from scratch.
