Email remains one of the most valuable channels for building customer relationships. It gives your business direct access to people who’ve chosen to hear from you, without having to rely on social media algorithms. But access to the inbox doesn’t automatically mean engagement. Your audience is busy, their inboxes are crowded, and your email has only a few seconds to earn attention, communicate value, and guide action.
This is what stood out during the judging process for Everlytic’s 2026 You Mailed It Email Marketing Awards. The strongest entries weren’t just well-designed or well-written – they showed clear strategic thinking, audience understanding, smart use of data, and a strong sense of what the reader needed next. Here we share eight practical tips from the judges to help you write and build better emails.
1. Start with Your Audience
Before you write your subject line or involve your designer, get clear on who you’re speaking to. What does this audience care about? What do they already know? What problem are you helping them solve? What action do you want them to take? The best emails are built around the reader, not the sender.
This matters even more when you’re dealing with complex topics like finance, healthcare, compliance, education, or technical product information. If your message is difficult, your job isn’t to make it sound impressive. Your job is to make it easier to understand.
Understanding the audience and using personalisation to speak to each segment effectively is how this retailer was able to increase revenue and heighten customer engagement.
2. Use Data to Make the Message More Relevant
Personalisation is more than adding a first name to a subject line. Strong email communication uses data to shape the experience – segmenting your audience by behaviour, location, lifecycle stage, interests, purchase history, engagement level, or customer type.
Take a loyalty rewards programme with three groups on the same list. Members who are actively earning points get a progress-style email: “You’re 200 points from your next reward – here’s how to get there.” Members who’ve been sitting on unredeemed points for months get a different message: “Your 850 points are about to expire – here’s what you can claim today.” Members who haven’t engaged in 90 days get a re-entry offer built around their last purchase category, not a generic “we miss you” banner.
Same programme, same week, three completely different emails – because three different behaviours call for three different messages.
3. Make Your Subject Line Earn the Open
Your subject line has one job: give people a clear reason to open your email. The judges responded well to subject lines that were short, specific, benefit-led, and relevant to the content inside the email. Personalisation, urgency, and curiosity can all work – but only when they feel natural and truthful.
Avoid being vague for the sake of being clever. If your subject line is too generic, your email may disappear. If it overpromises, you risk losing trust. Keep in mind that many people read emails on mobile devices, where subject lines are often truncated. Put the most important words at the beginning, so readers see your key message before the text is cut off.
4. Keep the Copy Simple and Human
Good email copy is quick to read, easy to understand, and written with people in mind. That doesn’t mean your writing has to be basic; it means it must be clear. To do this, use shorter sentences and break up long paragraphs. Also cut the jargon, acronyms, and formal phrasing that puts distance between your brand and your reader. A professional email can still sound warm, and a very technical email can still feel human. At the same time, a serious message can still be easy enough to follow.
As AI-generated content becomes more common, a clear and authentic brand voice matters even more. If every email starts to sound the same, the brands that sound human will stand out.
The one global email marketing trend we are seeing this year is a move towards writing email copy for both humans and AI. Here’s a few more of the trends that 2026 has seen, and what they mean for South African businesses.
5. Focus on One Clear Call-to-Action (CTA)
Many emails try to do too much. They ask people to register, read more, shop now, follow a page, download a guide, watch a video, and contact a team – all in one send. That creates confusion and weakens the user’s journey.
Here’s what that looks like in practice: a webinar invite that opens with “Register now,” then adds a secondary button for “Download our latest report,” a footer link to “Follow us on LinkedIn,” and a P.S. asking readers to “reply with questions.” There are four asks but no clear winner – and a click-through report that can’t tell you which CTA people preferred.
Compare that to a webinar invite with one button – “Save my seat” – repeated at the top and bottom of the email, with everything else (the speaker’s LinkedIn, a related report) mentioned in text only, with no competing buttons. Aim to have one action and one clear signal in your reporting.
A strong email can still have several sections, as many newsletters often do, but the hierarchy must be clear. The reader should know what the main message is and what to do next. If the action is clear, your reporting becomes clearer too.
Email marketing metrics do more than report what happened after the send. Here’s what metrics to measure and interpret to create messages that are relevant, trusted, efficient, and useful.
6. Design for Mobile First
Many people open email on their phones first, even when the message is work-related. That means your email needs to work well on a smaller screen.
Your buttons should be easy to tap, your images should load reliably, and your content blocks should stack neatly. This ensures your text is readable without having to zoom in. A good desktop design that displays accurately but breaks on mobile can damage the experience quickly. Before you send, test how your email displays across devices. A good mobile experience can be the difference between a quick click and a quick delete.
7. Use Design to Guide Attention
The design of your email should help readers navigate it with ease and shouldn’t compete with your main message. Use headings, spacing, imagery, buttons, and content sections to create a clear path to guide your reader.
Take a simple product email: add a headline stating the benefit, one hero image of the product in use, and a short paragraph of body copy. Then include a single button with plenty of white space between each element, so the eye knows where to land next. Now compare that to a similar email with three different fonts, a countdown timer, five product thumbnails, and a background pattern competing for attention. The offer is identical, but one version guides the reader, and the other exhausts them.
GIFs, countdown timers, calculators, videos, and gamified elements can add interest, but only when they support the goal of the email, not when they’re decoration for its own sake. The best design choices feel intentional. They guide attention, improve readability, and make the message easier to act on.
8. Test, Measure, and Improve
Email isn’t a send-and-forget channel. Use your campaign reports to understand what worked and what didn’t work. Look at open rates, click-through rates, heatmaps, device data, unsubscribe patterns, and conversion activity where available. Use A/B testing to help you learn what your audience responds to. Start with simple tests: two subject lines, different calls-to-action, or alternative send times. The goal isn’t to collect data for its own sake. It’s to use those insights to make your next email stronger.
Heatmaps can show where readers are paying attention and which content blocks are attracting the most clicks, helping you make better layout and hierarchy decisions in future campaigns.
Create Emails People Want to Read
Writing a good email isn’t about adding more content, more design elements, or more links. It’s about making smart choices. Know your audience, use your data, keep the message clear, design with purpose, have a next obvious step, and use your results to keep improving. Your audience has already given you permission to reach them. Make that inbox moment count.

Frequently Asked Questions (FAQs)
What Makes an Email Marketing Subject Line Effective?
An effective subject line is short, specific, and benefit-led – it tells the reader what’s inside and why it matters to them. Personalisation, urgency, and curiosity can all improve open rates, but only when they’re truthful. A subject line that overpromises damages trust when the email is opened, and a subject line that’s too vague gets lost in a crowded inbox.
How Does Personalisation Improve Email Engagement?
Personalisation works best when it goes beyond a first name and uses data (behaviour, purchase history, lifecycle stage, or engagement level) to shape what each reader sees. Segmenting an audience this way means different groups receive different, more relevant messages instead of one generic send, which makes readers feel understood.
Why Should an Email Have Only One Call-to-Action (CTA)?
An email with a single, clear CTA gives the reader an obvious next step and gives the sender a clean way to measure results. Emails that ask readers to register, shop, download, and follow all at once dilute the message and make it harder to tell which action drove engagement.
Why Does Mobile Design Matter for Email Marketing?
Most people open email on their phones first, regardless of whether the message is personal or work-related. If buttons are hard to tap, images fail to load, or text requires zooming, the reader is likely to delete the email rather than persist. Testing an email’s display across devices before sending helps prevent this kind of drop-off.
What Should Marketers Measure after Sending a Campaign?
Marketers should review open rates, click-through rates, device data, unsubscribe patterns, and conversion activity to understand what worked and what didn’t. A/B testing (comparing two subject lines, calls-to-action, or send times) turns those results into insight that improves the next campaign, rather than just producing data for its own sake.
How Can a Brand Keep Its Email Tone Human as AI-generated Content Increases?
A clear, consistent, and authentic brand voice becomes more valuable as more email content is generated by AI. Emails that sound distinct (warm, plain-spoken, and written for a specific reader rather than a general audience) stand out precisely because so much of what lands in an inbox now reads the same.
