Go to the Design section and check out the preview - this is how the pop up will look at your store.
Now you can change the colors and fonts from this page, save (always important) and click the preview button to see the results.
If you don't have the Email Builder enabled, insert your logo's URL so it will show up on every email sent from the app.
After uploading the images, make sure you select them by adding the check mark sign.
In order to remove the default image shown on the popup (the gift image), click the star icon on the image that you've chosen to replace it with.
Remember to save after each change and check the preview button to see the changes.
