Every block in the email editor has its own settings, separate from the email-level styles set in the [Styles panel](/emails/email-styles). This lets you customize individual blocks without affecting the rest of your email. To access block settings, select a block and click **Block Settings** in the sidebar.

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](/emails/email-styles). For a background image that spans multiple blocks, use a [1-column layout](/emails/editor/columns-and-layouts) 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 in the block settings. *** ## 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.

In **Block Settings**, click **+ Add visibility condition**, choose whether recipients must be **on the list** or **not on the list**, and pick a list. When the email is sent, only recipients who match the condition get the block; everyone else gets a version of the email without it. The content is removed from their email entirely — not hidden with CSS — so it never appears in their inbox or their view-in-browser page. * **On the list** sends the block only to people on the list — for example, an update just for volunteers. * **Not on the list** sends the block only to people who aren't on the list — for example, a sign-up pitch hidden from people who already signed up. * Blocks with a visibility condition show a small filter badge on the canvas and next to the Block Settings title. * To apply a condition to several blocks at once, select multiple blocks (shift-click or cmd/ctrl-click) and use **Add Visibility Condition** in the sidebar. * Recipients are matched by their Planning Center person. Recipients imported from a CSV aren't on any list, so blocks limited to a list are removed for them, and blocks hidden from a list are included. When you send a conditional-block email to a CSV audience, we'll warn you about this on the send confirmation. * Public email archives and RSS feeds show the email as someone on none of the lists would receive it: content limited to a list is never published publicly, while content hidden from a list is included. * Moving a block into a column layout removes its visibility condition (conditions only work on top-level blocks) — you'll see a warning when this happens. The editor preview and test sends always show the full email with every block included. *** ## 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.
