This is an image issue. In the desktop preview, a small image (of a signature) appears as intended, flush left. But in the mobile preview it appears center-justified. Is there a way to get it to appear flush left in the mobile view, too?

Thank you for sharing these screenshots! They helped to understand exactly what you are experiencing. You are seeing this alignment change because our templates are mobile responsive. Being mobile responsive means emails will resize itself based on the screen it is being viewed on. Because of this images will resize to fill the whole screen and blocks will stack itself to center align. I apologize for any inconvenience this may cause. While we do not currently have a resolution, being able to control the mobile version of your emails is a feature request I have tracked in your account in the meantime.
I'd just like to second this bug report. We have different signatures we'd like to include - sometimes from our principal, our president, etc. - and this is something that was not a problem with old templates.
Thank you for your feedback! We appreciate it and will submit it to our engineers for review. Thanks!
