Background Image New Email Editor

Are you setting the background image on the structure (not the contents)? If you're setting it on the Structure, on the Styles tab, under the image source link, there should be a section for "Image Placement." Are you able to choose "center" for your placement? 

When I do that on my end, that's how I get the image to be centered on my email area instead of spanning the full width of the editor panel.

What you’re seeing is actually expected behavior in Marketo. When you apply a background image at the section (row) level, it will span the full container width — there isn’t a setting in the editor that limits it to just the two inner columns.

To get the background only behind the 2-column area, you’ll need to apply the background to a fixed-width inner table instead of the full-width section. 

• Keep the outer wrapper at 100% width

• Add a centered inner container (for example, 600px wide)

• Apply the background image to that inner container

• Place your two columns inside that container

That way, the background image will sit only behind the two columns and won’t stretch across the entire page.

If you’re using a guided template, this would require adjusting the HTML template itself — it can’t be controlled purely from the email editor UI.
