How do I create a non-blocking, banner-style In-App Message?

To show an in-app message as a banner at the top or bottom of the screen instead of a full-screen takeover, you no longer need custom HTML. Set the position in the built-in in-app editor.

Recommended: position the in-app in the built-in editor

1. Go to Content → In-apps (Rich media) and open or create a template in the built-in editor.
2. Click In-app settings in the top bar.
3. Set Position on Screen to Top or Bottom (the other options are Fullscreen and Center).
4. Optionally set Present Animation / Close Animation (None, Fade, Left, Right, Up, Down, or Default) and Animation Duration (100–3000 ms).
5. Enable Swipe to Close in the directions you want, and configure Show close button (position, background, icon colour).
6. Keep the template short — design it at banner height so it does not fill the screen.

Note: these in-app settings apply to iOS and Android Native only. Currently None and Fade animations work on Android; on iOS the message appears and disappears instantly.

Alternative: Modal Rich Media

If you want a popup/dialog presented over the current screen with the background dimmed rather than a full-screen page, use Modal Rich Media. This requires a one-time setup by your development team:

You can also upload a custom HTML ZIP template if you need complete control over markup; see the Rich Media templates syntax and Rich Media customization guides.
