Design an Inbox inbox-design
Inbox design governs how each message is rendered to targeted profiles within the inbox surface. The configuration encompasses the inbox template, list and expanded presentations, and read-state indicators that distinguish new messages from those already viewed.
For the complete procedure to create an inbox campaign, refer to Create an Inbox.
-
Open the Content tab of the Inbox campaign you created.
-
Set the Container title.
-
Select an inbox layout:
-
List layout: shows each content card in a vertical list so profiles can scroll through messages and open them one at a time.
-
Carousel layout: shows cards in a horizontal carousel so profiles can swipe or move sideways through highlights without leaving the inbox surface.
-
-
Specify the inbox capacity, the maximum number of content cards the inbox is configured to hold.
-
Toggle Unread settings and configure how unread messages are indicated:
-
Unread icon image URL: Provide the image shown next to or on unread items; add a dark-mode URL so the icon stays visible and on-brand when the app or site uses a dark theme.
-
Background colors: Set colors for light and, if needed, dark mode so the unread treatment matches your brand and remains readable against the inbox background.
-
Placement: Use the drop-down to choose where the unread icon appears to align with your layout.
-
-
Under Empty state, configure what profiles see when there are no messages to display:
-
Message text: Short text that explains the inbox is empty or suggests a next step.
-
Image URL: Optional illustration or graphic for light mode that reinforces the empty state instead of showing a blank area.
-
Dark image URL: Optional image tuned for dark mode so the empty state looks correct without low contrast or harsh edges.
