Most email opens happen on mobile devices and a one-column wall of text or a desktop-only multi-column layout destroys the reading experience for the majority of your audience. Responsive email design uses CSS media queries and fluid layouts to adapt your email's structure to the screen it is being viewed on. The right email platform makes it easy to build or choose templates that are truly responsive rather than just "mobile-compatible" in the loosest sense.

A truly responsive email uses CSS media queries to actively change the layout, font sizes, spacing, and element visibility based on screen width. Mobile-compatible emails often just use a single-column fluid layout that scales linearly without changing structure. True responsiveness means a two-column desktop layout collapses to single-column on mobile, images resize proportionally and fill the available width, and font sizes may increase on small screens for readability. The distinction matters because many platforms claim mobile-compatible templates that look technically readable on mobile but are not actually optimized for the mobile experience.
Most email platforms have a mobile preview mode in the editor, which is a good starting point but not always fully accurate. More reliable methods include sending test emails to your own devices and checking on an actual phone, using inbox preview services like Litmus or Email on Acid which render your email in dozens of real email clients at different sizes, or using browser developer tools to simulate mobile viewports on the web version of email clients like Gmail. Testing on at least a large phone (like an iPhone Pro Max) and a small phone is a practical minimum, since layouts often break differently at extremes.
Most email designs use a 600px maximum width for the email body on desktop, which fits comfortably in most desktop email clients without requiring horizontal scrolling. On mobile the email should scale to fill the viewport width, typically 320px to 430px depending on the device. Using max-width: 600px on your container element and width: 100% on inner elements is the standard approach that handles both sizes well. Avoid fixed pixel widths on content elements since they will overflow on narrow mobile screens.
The standard technique for multi-column responsive email is using inline-block or table-based columns for desktop that stack vertically on mobile via CSS media queries. When the screen width is below a breakpoint (typically 480px to 600px), the media query changes each column to full width so they flow vertically instead of side by side. Most email builders handle this automatically in their multi-column block types, but if you are coding emails manually, the fluid hybrid approach using a combination of table cells and inline-block elements gives you the most consistent cross-client behavior.
Single-column layouts are inherently more mobile-friendly and significantly simpler to code and maintain. Many successful email programs use exclusively single-column layouts and never have mobile layout issues. The tradeoff is design flexibility: some content types like product grids, comparison tables, or feature showcase sections benefit visually from multi-column layouts on desktop. For most newsletter and transactional email use cases, single-column is genuinely the right choice. Multi-column is worth the added complexity only when the content specifically benefits from the side-by-side comparison that a grid layout provides.
Most modern email clients support CSS media queries, including Apple Mail, iOS Mail, Gmail on iOS, Android mail apps, and most webmail clients. The notable exception is Outlook on Windows, which uses Microsoft Word's rendering engine and has notoriously poor CSS support. Outlook does not support media queries in most versions, which is why many responsive email techniques use the fluid hybrid or spongy approach that relies on percentage widths rather than media query breakpoints. If Outlook is a significant part of your audience, prioritizing fluid layouts over media-query-dependent responsive techniques is the safer path.
