There are several reasons why marketers might opt for a single column layout:
Mobile Optimization: With the majority of users now checking emails on their mobile devices, a single column layout ensures that content is easily viewable on smaller screens. Simplicity: A clean, uncluttered design makes it easier for recipients to focus on the key message. Speed: Single column emails tend to load faster, improving user experience and reducing the likelihood of abandonment. Accessibility: Single column layouts are generally more accessible for people using screen readers.
