Every block in the email editor has its own style settings, separate from the email-level styles set in the Styles panel. This lets you customize individual blocks without affecting the rest of your email. To access block styles, select a block and click Block Style in the sidebar.

​
Background Color

Set a custom background color for the block. This color appears behind the block’s content and is independent of the email’s overall background color.

​
Background Image

Add a background image behind the block’s content.
  • Choose an image from your asset library.
  • Set the image position: top, center, or bottom alignment.
Background images work best when card style is turned off in Email Styles. For a background image that spans multiple blocks, use a 1-column layout and apply the background to the column.

​
Padding

Control the space inside the block, between the block’s edge and its content. Use the slider to set a uniform value on all sides. Click the expand icon to the right of the slider to set each side individually (top, right, bottom, left).
For edge-to-edge images, set padding to 0 on the block style.

​
Corner Radius

Round the corners of a block. Use the slider to set a uniform radius for all four corners. Click the expand icon to configure each corner independently (top-left, top-right, bottom-right, bottom-left).

​
Margin

Control the space outside the block. Use the slider to set a uniform value, or click the expand icon to set each side individually.

​
Borders

Add borders to any block. Choose a border color and set the width using the slider. Click the expand icon to set a different width for each side (top, right, bottom, left), which is useful for effects like a thick bottom border or an accent line on one edge.

Tips

  • Combine a background image with padding to create breathing room around your content.
  • Use corner radius on image or card blocks to create a softer, rounded look.
  • Margin is helpful for creating visual separation between blocks without adjusting the block gap in your column layout.
