Here are 10 practical tips to help you design emails that don’t just get opened, but convert.
Start with a Clear Goal
Before you design or write anything, decide what you want the reader to do. Whether it’s clicking through to a webpage, downloading a guide or signing up for an event, every email should focus on one primary action. Too many messages will dilute results.
Write Compelling Subject Lines
Your subject line and preview text determine whether your email gets opened. Keep subject lines short, relevant and benefit-led. Use the preview text to add context or urgency to the goal of your email, rather than repeating the subject line.
Focus on Mobile-First Design
The majority of emails are opened on mobile devices.
Use a single-column layout, legible font sizes and buttons that are easy to tap. If your email is hard to read or navigate on a phone, engagement will drop quickly.
Keep your Layout Clean and Scannable
Most readers scan emails rather than read them word for word.
Use short paragraphs, headings, bullet points and white space to guide the eye and make key information easy to digest at a glance.
Make your Call to Action obvious
Your call to action (CTA) should stand out clearly from the rest of the email. Use action-focused wording such as “Register now” or “Download the guide”, and make sure the button colour contrasts with the background so it’s easy to spot.
Use Imagery with Purpose
Images can enhance your message, but too many can slow loading times or distract from your goal. Choose visuals that support the content and reinforce your brand, and always ensure your message still makes sense if images don’t load by using Alt Text.
Stay Consistent with your Brand
Emails should feel like a natural extension of your website and wider marketing. Use consistent colours, fonts, tone of voice and logo placement to build recognition and trust with your audience.
Personalise where it adds Value
Simple personalisation; such as using a recipient’s name or tailoring content to their interests, can significantly improve engagement. Focus on relevance rather than novelty; meaningful personalisation works best.
Optimise for Accessibility
Good email design should be inclusive. Use readable fonts, sufficient colour contrast, clear button labels and descriptive alt text for images. This improves usability for everyone, not just those using assistive technologies.
Test, Measure, Improve
Even small design changes can have a big impact. A/B test subject lines, layouts, CTAs or send times, and review performance metrics such as open rates and click-through rates. Use the insights to continuously refine future campaigns and improve your email marketing strategy.
By applying these ten tips, you can create emails that engage your audience, strengthen your brand and deliver measurable results.
