Settings
Under this tab you can adjust Content area width, background color, content area background color, default font, and link color.
Rows
Different types of rows are available to insert into the message.
Rows are structural units that define the horizontal component of a section of the message by using columns. You can use from one to four columns.
Use of more than one column allows you to put different content elements side by side.
You can add to your messages all the structural elements you need, regardless of the template you selected when you started.
Every row has its own settings, which gives you the kind of flexibility that before was only achieved with hand-coded email.
For example, you can select a background color for the entire row, only the message area, or a specific column within it.
Content
This section includes a series of tiles that represent the different kinds of content you can use in your message. More will become available in the future.
To use them, just drag one inside a column, it will auto-adjust to the column width.
Under Content Properties every content block has its own settings.
