I am new to the world of HTML and CSS. I apologize if this question seems trivial, as I have searched extensively online with no success!
You can access my email HTML template here. The issue I am facing is:
The top and bottom padding around the background image in the email appears too large on mobile devices (desktop view is fine). I am struggling to reduce it as all padding in the HTML code seems to be either 0 or 10, leaving me unsure of what might be causing the problem.
