What is required if you want to have different looks for emails on mobile and desktop?

Using a single template with conditional formatting is effective for achieving different looks for emails on mobile and desktop. This approach allows for a more efficient workflow, as you don't have to create and maintain two separate templates. Instead, you can design one template that adapts its layout and styling based on the device being used to view the email.

Conditional formatting involves using media queries and specific CSS styles that detect the device’s screen size or orientation. By implementing this method, you ensure that the email content remains visually appealing and functional on both platforms, enhancing the user experience through responsive design. This flexibility not only saves time in development and iteration but also ensures consistency in branding across devices.
