Gmail to Roll Out Support for Responsive Email Design in 2024: What It Means for Marketers

Responsive email design, which allows email content to automatically adapt to different screen sizes and devices, has been a best practice and an increasingly essential strategy for email marketers for years now. However, one major holdout has long been a thorn in email designers‘ sides: Gmail, the world‘s most popular email service with over 1.5 billion active users, has not supported responsive email coding techniques.

But that‘s all set to change very soon. In a major announcement, Google has revealed that Gmail will begin rolling out support for responsive email design by the end of 2023. This update will allow the email content and layouts to automatically adjust to the recipient‘s screen size, providing a much better experience for Gmail users reading emails on their smartphones.

As an email marketing expert, I believe this move is a game-changer that will have a profound impact on the email design landscape and email marketers‘ strategies in 2024 and beyond. Let‘s dive into the details of Gmail‘s responsive design update, what it means practically for email marketers and Gmail users, and how to make the most of this change.

The Responsive Email Design Challenge for Gmail

To understand the significance of Gmail supporting responsive design, it‘s important to know how Gmail has handled responsive coding up until now and why it‘s been such a pain point for email marketers.

Responsive email design is typically achieved through a combination of specific HTML and CSS code, particularly CSS media queries. Media queries allow you to specify different style rules based on the width of the screen the email is being viewed on. This enables you to create fluid layouts that dynamically adjust sizing, stacking, and visibility of different email elements to ensure the design looks great on any device.

Here‘s a simple example of CSS media query code for responsive email:

@media only screen and (max-width: 600px) {
  .column {
    width: 100%;
    display: block;

This code tells the email client that for screens 600px wide or smaller (i.e. mobile devices), elements with the class "column" should be displayed as full-width blocks stacked on top of each other, rather than side-by-side columns.

The problem is, Gmail has not supported CSS media queries, meaning this responsive code would simply be ignored. No matter how well-designed your responsive email was, it would look broken or distorted to Gmail app users on iPhones and Android phones.

Gmail‘s lack of responsive support has forced email developers to use a variety of sub-optimal workarounds and fallback techniques, such as:

  • Coding the entire email to be single-column, large text, and mobile-friendly by default
  • Using the "mobile-first" approach of defining all mobile styles in the main CSS and then overriding them for desktop using media queries (which would be ignored on Gmail mobile)
  • Implementing complex hybrid coding that combines fluid tables, conditional Ghost tables, inline CSS and media queries to achieve a semi-responsive effect

None of these quite achieve a truly mobile-optimized experience in Gmail the way full media query support does. This has been especially challenging given Gmail‘s huge market share – over 27% of all emails are opened in a Gmail inbox according to Litmus‘ 2023 market share data.

How Gmail‘s Responsive Design Update Works

Gmail‘s responsive design support will roll out in two key phases:

  1. Support for CSS media queries across all Gmail platforms, allowing responsive code to properly resize and reformat emails based on screen width
  2. Support for embedded style block classes, allowing cleaner and more efficient responsive coding compared to using inline CSS styles

This update will apply to both Gmail‘s web interface and the Gmail mobile apps for iOS and Android. For now, only personal Gmail accounts are confirmed to be getting the responsive update – support for enterprise G Suite accounts is expected to come later.

With this change, all the advanced responsive design techniques that email marketers have used for other email clients will now work in Gmail too:

  • Fluid hybrid designs that combine percentage-based tables and media queries for layout flexibility
  • "Spongy" or "fab four" images that can automatically resize while maintaining aspect ratios
  • Show/hide toggles to display or remove different content modules based on screen size
  • Interactive elements and accordions that collapse or expand sections for better usability
  • Hamburger menus to simplify navigation on smaller screens
  • Enlarged text and CTA buttons for better touchscreen tappability

In short, Gmail will now properly handle pretty much any modern responsive email code, unlocking a huge range of design possibilities for crafting mobile-optimized Gmail experiences.

Why Responsive Email Design Matters for Marketers

So why is responsive design so important for email marketers in the first place? The data tells a clear story:

  • Over 60% of email opens now happen on mobile devices (Litmus)
  • Mobile readers who open an email a second time from their computer are 65% more likely to click through (Campaign Monitor)
  • Emails that display poorly on mobile may be deleted within three seconds by 70% of consumers (Adestra)
  • Responsive email designs generate 24% more clicks on mobile (MailChimp)
  • 80% of respondents say they‘re likely to engage with an email specifically because it "displayed well on their smartphone" (Adobe)

Clearly, providing a great mobile inbox experience is essential for driving email engagement and conversion in our mobile-first world. And with mobile commerce steadily rising to an expected 73% of total ecommerce revenue by 2025 according to eMarketer, integrating your email and mobile strategies is key to capturing mobile sales.

Gmail‘s mobile email market share makes their embrace of responsive design especially meaningful for marketers. Gmail has over 1.5 billion active users worldwide and 27% of all email opens. In some industries like tech, Gmail‘s share of opens is even higher. For many brands, Gmail users represent a huge portion of their email audience.

In 2024, optimizing the email experience for these Gmail users on smartphones and tablets will become much easier and more effective. Brands will have more design flexibility to craft high-converting mobile email experiences, taking advantage of Gmail-specific tactics like AMP for interactive elements. This has major implications for email engagement, list growth, and ultimately email marketing ROI.

Responsive Email Design Best Practices & Tips for Gmail

While Gmail‘s update removes key technical hurdles to implementing responsive design, email marketers and designers still need to follow best practices to ensure their campaigns are successful on mobile. Here are some key tips I recommend based on our responsive email design projects for leading brands:

  1. Keep layouts simple: Use a single-column layout for the most mobile-friendly experience. Limit yourself to 2-3 columns max for desktop.

  2. Make text readable: Use a minimum 16px font size for body copy and 22px for headlines on mobile screens. Stick to easily readable fonts.

  3. Prioritize tap-friendly CTAs: Make buttons at least 44x44px with plenty of surrounding whitespace for easy tapping. Use clear, action-oriented CTA copy.

  4. Optimize image sizes: Compress images to under 250KB each for faster load times. Use retina-optimized 2x images sparingly. Implement lazy loading for image-heavy emails.

  5. Simplify navigation: Limit your primary navigation to 3-5 key links. Consider using an expandable hamburger menu for secondary links.

  6. Test across devices: Use email preview tools like Litmus to QA your designs across a range of screen sizes, email apps, and devices. Don‘t forget to test with images blocked.

  7. Implement responsive targeting: Leverage mobile-specific segmentation, personalization, and automated triggers to deliver the most relevant content to Gmail mobile readers.

Remember, even with the new responsive support in Gmail, not every email client will handle your media queries and responsive code the same way. It‘s still important to design defensively, test extensively, and provide fallbacks for older email apps and less common devices.

Examples of Responsive Email Campaigns

To see what great responsive email design looks like in action, let‘s examine a few examples from leading brands:


Ride-sharing giant Uber uses responsive design to create sleek, on-brand emails that are easy to engage with on mobile. They keep their message copy concise, make CTA buttons large and prominent, and dynamically hide some secondary content on smartphone screens. The result is an email that‘s quick to read and act on for busy mobile users on the go.

Airbnb takes a visual-forward approach to their responsive email designs, showcasing large, enticing destination photos. But they‘re thoughtful about how these images scale down for mobile screens, using percentage-based sizing and compressed files to ensure fast loading. They also use finger-friendly star ratings and bulleted lists to highlight key information on mobile.

Email testing platform Litmus naturally has some of the most advanced and thoughtful responsive emails around. They make great use of collapsible accordions and interactive hot spots to pack more content into a mobile-friendly format. They‘re also a great example of how to design responsively for dark mode.

The Future of Email Marketing is Mobile-First

Gmail‘s announcement to start supporting responsive email design is just the latest signal that marketers must adopt a mobile-first mindset across all their channels and tactics going forward. We‘re firmly in the age of the smartphone, and email is no exception.

Consider that mobile email will account for 77% of email opens by the end of 2023 according to Litmus‘ Email Client Market Share Trends report. What‘s more, Adobe‘s 2023 Email Usage Study found that 60% of consumers prefer to check email on their smartphones – a figure that rises to 73% for the 18-34 age group.

It‘s clear that optimizing for mobile screens and behaviors will only become more important for email marketers as these trends continue. Responsive design is a foundational part of this, but it‘s just the beginning. Savvy email marketers will adopt additional mobile-first tactics like:

  • Embedding interactive AMP elements in Gmail emails for app-like experiences
  • Leveraging mobile behavioral data and geolocation for hyper-personalized content and offers
  • Implementing omnichannel messaging to deliver coordinated email, mobile push, SMS and in-app communications
  • Adopting modular email architectures for more flexible, mobile-friendly design systems
  • Prioritizing accessibility for mobile email users who rely on assistive technologies

As smartphones become ever-more central to how people communicate, consume content, and make purchases, marketers will need to continually push the boundaries of what‘s possible with mobile-optimized email. Gmail embracing responsive design is an important step forward in this direction, empowering brands to deliver better experiences to more mobile inboxes than ever before.
