Crafting an engaging, compelling email that converts has become more critical than ever in this ever-evolving digital marketing world.
Since there are many competitors on the market looking for placements in the same inboxes, your email design can be one of the most critical deciding factors for many when choosing to click or delete an email.
With new devices, email clients, and consumer behaviors emerging every year, staying updated with the latest email design best practices in 2025 is essential to maintain a competitive edge.
So, if you are ready to review some essential email design best practices, we are here to walk you through the best practices that every brand should implement in 2025 and beyond.
Sorry to burst your bubble, but email is far from dead; it is one of the highest ROI-generating channels marketers can use to generate traction.
However, your message might never reach its full potential without the right email design.
A well-designed email:
In 2025, responsive email design best practices, mobile email design best practices, and HTML email design best practices are no longer just nice to have. They have become non-negotiables as they can help propel your email ahead of the others.
Before your beautifully designed email ever gets the chance to be read, it has to be opened. And that doesn’t happen by accident—it starts with how your message shows up in your subscriber’s inbox.
In a sea of promotions, newsletters, and spam, your email needs to look trustworthy, relevant, and worth clicking on.
Here’s how you can set the stage for success:
Think of your sender name as your handshake. It's the first thing people notice when your email hits their inbox. If you’re using generic or cold sender names like “[email protected]” or “[email protected],” you’re missing a big opportunity to build trust. These feel impersonal—and let's be honest, most people associate them with spam or customer service bots.
Instead, use a recognizable and friendly sender name that reflects your brand or even an objective team member. For example: (we are using Mailmunch; you can use your own business name where needed)
When your subscribers see a familiar name, they’re more likely to trust and open it.
Your subject line is your email's headline. It's what convinces someone to stop scrolling and actually click. And with shrinking attention spans, you only get a few seconds to make an impression.
So, what makes a subject line irresistible?
And remember—test different styles! What works for one audience might fall flat for another.
The preheader is the line of text that appears next to or below the subject line in most inboxes. It’s basically your second chance to convince someone to open the email. Think of it as the email’s subheadline—it gives context, adds a little teaser, or reinforces urgency.
Instead of leaving this to default to something boring like “View this email in your browser,” be intentional. Try something like:
The preheader and subject line should work together like a power duo—one grabs attention, the other supports the pitch.
With Mailmunch, you can easily customize your sender name, subject line, and preheader text during the email creation process. Everything’s built to help you boost open rates without the hassle.
Design isn’t just about looking good anymore—it’s about working well for everyone. Whether someone’s opening your email on a phone, tablet, desktop, or using assistive technology, your content should be easy to navigate and pleasant to experience. That’s what modern email design best practices 2025 are all about: inclusivity, flexibility, and functionality.
Here’s a stat you can’t ignore—over 60% of emails are opened on mobile devices. So if your email looks clunky or broken on a phone, you’re likely losing subscribers before they even see your offer.
Mobile email design best practices recommend:
The best part? With Mailmunch, you don’t have to code a single line. Their drag-and-drop email builder automatically creates responsive email designs that adapt perfectly across devices. Just design, preview, and send—it’s that easy.

Not only is this the right thing to do, but it also boosts engagement—and it’s another area where Mailmunch shines. Their tools are designed to help you build accessible and responsive emails without needing to be a design expert.

Accordions, sliders, and collapsible sections enhance engagement and keep emails compact. These are increasingly popular in marketing email design best practices.
When done right, GIFs can add movement and personality. Make sure they don’t affect load times. Mailmunch’s lightweight assets help avoid that and help you create meaningful gifs that work well with your content.
When it comes to email marketing, how your email looks is just as important as what it says. A well-structured layout makes your message easy to read and increases the chances of your audience taking action. In this section, we'll break down how to create a layout that’s clean, logical, and visually appealing—no design skills required!
Keep your email header simple and clutter-free. All you really need is your logo, maybe a navigation bar, and a quick, clear statement about your offer. This sets the tone right away without overwhelming the reader.
Quick tip: If you're running a promo or sale, a short banner like “Spring Sale: Up to 30% Off!” at the top can work, just don’t overload it.
People scan emails quickly, so your content needs to be laid out in a way that flows naturally. Start with the most important info above the fold (the part visible without scrolling), and use layout patterns like the F-pattern or Z-pattern to guide the reader’s eyes.
Break things up with headings, subheadings, and visuals so it’s easy to skim and understand the message.
Your CTA is the main event. It’s the action you want the reader to take—buying something, signing up, or downloading a resource. Use clear, action-oriented text and make it stand out visually so no one misses it. One strong CTA is better than several weak ones.
Your emails should feel like a natural extension of your brand. From the design to the wording, consistency helps build trust and recognition. In this section, we’ll look at how to reinforce your brand in every email you send and make your messages feel more personal and relevant to each reader.
Make sure your emails match the look and feel of your brand. That means using your colors, fonts, logo, and tone of voice—just like you do on your website and social media. Keeping everything cohesive helps customers immediately recognize your brand.
Example: If your site has pastel blues and a clean, rounded font, keep that same vibe in your emails.
Personalized emails perform better—plain and simple. Go beyond just using someone’s first name. Include dynamic content like location-based offers or triggered emails based on behavior (e.g., abandoned carts, past purchases). The more relevant the message, the more likely someone is to engage with it.
A lot of marketers forget about the footer—but it’s actually a key part of your email. It builds trust, helps with legal compliance, and gives readers the tools to stay connected with your brand. This section covers what to include in your footer and how to make sure you're meeting important email marketing laws.
Your footer should include a few basics:
You can also add a small tagline to remind readers what your brand stands for.
To stay on the right side of email marketing laws like CAN-SPAM, GDPR, and CASL, make sure your footer includes:
This isn’t just about avoiding penalties—it also shows your audience that you respect their privacy and their inbox.
You’ve built your email and hit send—now what? This section is all about measuring success and improving your results. By testing different elements and tracking performance, you’ll learn what works best for your audience so each campaign gets better over time.
Want to know if an emoji in your subject line makes a difference? Should your CTA go at the top or bottom? That’s where A/B testing comes in. You test two versions of an email (changing just one thing) and see which one performs better.
Just make sure you’re only testing one variable at a time, or you won’t know what made the impact.
After you send your email, it’s important to monitor the results. Pay close attention to:
