1. Hyper-personalisation: the new normal

Remember when just adding a first name to an email felt personal? Well, those days are long gone. In 2025, hyper-personalisation is the name of the game. We’re talking about emails that feel like they were crafted just for you, thanks to advanced data analytics and AI. 

Imagine dynamic content that changes in real-time based on what you’re into, where you are, or even what you’re doing. Using user behaviour, preferences, and their location makes this all possible.  Predictive personalisation takes this a step further, with AI algorithms anticipating which content will resonate best with each of your subscriber, engagement rates are set to soar.  

This level of personalisation not only enhances user experience but also strengthens the connection between brands and their audiences. It’s all about making your audience feel seen and valued. 

Behavioural triggers enable automated emails to be sent based on specific user actions, ensuring a more responsive and relevant communication flow. This level of personalisation not only enhances user experience but also strengthens the connection between brands and their audiences. 

2. AI: the silent partner in email marketing

Artificial intelligence has evolved from being just a buzzword to becoming an indispensable ally in the email marketer’s toolkit. In 2024, AI was primarily seen as an assistive tool, helping marketers streamline their processes. Fast forward to 2025, and AI is not just assisting—it’s taking the lead in all corners of email marketing.  

From crafting killer content to nailing the perfect send time, AI’s got your back. AI-powered tools can generate compelling content and craft captivating subject lines that resonate with your audience, while looking out for your brand’s unique voice. AI now offers the ability to create distinct personalities and save target groups, enabling more personalised and effective marketing strategies. 

What’s more, AI has become the master of send time optimisation, pinpointing the perfect moment to reach each subscriber. This feature actually exists within Maileon for years already, talk about staying ahead of the curve. Send time is like having a personal assistant who knows exactly when your audience is most likely to open their mail, making sure your mail ends up at the top of their inbox at the right time. 

Despite these advancements, the human touch remains irreplaceable. The most successful marketers in 2025 are those who strike the perfect balance between AI’s efficiency and the authentic personality of their brand. It’s all about making sure technology enhances, rather than overshadows, your message. So, while AI is doing the heavy lifting, your unique voice and creativity are what truly connect with your audience. 

3. Interactive emails: engagement in the inbox

Static emails will be a thing of the past, with more developments and the need to stand out in the sea of emails, interactive content is the future. Gamification elements like quizzes and polls aim not only to entertain, but also to collect valuable data. Dynamic visuals such as carousels and sliders make emails feel more like interactive web pages.  

While these features can enhance engagement, they can be tricky to implement and may not always work perfectly for all email clients. Providers like Apple and Gmail seem to respond well to these elements, but tools like Outlook lag behind. This means your emails might need alternatives depending on how complex you want to go. For beginners, tools like Nifty Images offer a user-friendly way to create engaging and personalised content. These interactive elements not only captivate audiences but also provide essential first-party data, crucial in today’s privacy-conscious world. 

4. Deliverability: the ongoing battle for the inbox

Reaching the inbox is more daunting and crucial than ever. Email providers are continuously refining their algorithms to weed out unwanted content. In 2024, we witnessed restrictions tightening, particularly with major players like Google and Yahoo. We don’t expect other to lag far behind. 

To keep up, AI-powered spam detection can be your best friend, helping marketers stay ahead of increasingly sophisticated spam filters through content optimisation. But a little common sense goes a long way as well. It’s all about tailoring your content to individual engagement levels and ensuring emails resonate with the reader. Set some guidelines in your emailing strategy this year, and your emails will always fly through to the inbox.  

As we move forward, it’s wise to prepare for a future where we rely less on third-party data. Focus instead on building direct, meaningful connections with their audience. 

5. Mobile-friendly design and dark optimisation

In 2025, the notion of mobile-friendly design is stepping up its game. It’s not just about being responsive; it’s about crafting an experience that’s tailor-made for mobile users from the get-go. With a staggering 60% of emails being opened on mobile devices, ensuring your design is spot-on for smaller screens is crucial. Think about it: are your buttons within thumb’s reach? Are your images sharp and snazzy enough to catch the eye? And let’s not forget the layout—will everything land where it should when the screen shrinks? As mobile continues to reign supreme, optimising for these devices isn’t just a nice-to-have any more; it’s a must for any savvy email marketer. 

Meanwhile, as night owls everywhere rejoice, dark mode is having its moment in the spotlight. Optimising emails for this moody viewing preference is no longer optional—it’s essential. There is no golden standard way to do it, but your brand should be recognisable even in dark mode. Don’t have anything set up yet? Let your contacts decide. Here are some ideas: 

• Enter smart colour inversion. 

• Adjusts hues and contrast to keep your emails looking sharp in the dark.  

• And don’t forget those images; using transparent backgrounds ensures they shine in both light and dark modes.  

Will 2025 be the year of standardising Dark Mode among the different email clients managed by Microsoft, Google and Apple? Probably not, so make sure to keep testing and keep things simple and let your contacts decide. With dark mode’s popularity on the rise, catering to this trend not only pleases the eye but also boosts engagement. 

6. Privacy-first approach: building trust through transparency

As global data privacy regulations tighten, building trust through transparency is more crucial than ever for successful email marketing in 2025. It’s all about creating a foundation of trust with your audience. How do you do that? By turning to zero-party data—encouraging subscribers to voluntarily share their information through engaging preference centres and interactive elements. A preference centre is a feature that allows your email subscribers to manage their own settings and preferences regarding the emails they receive from you. This approach not only respects user’s privacy but also enhances personalisation, making your emails feel even more personal. 

Implementing clear consent mechanisms is key. Robust opt-in processes and user-friendly preference management tools ensure your subscribers feel in control of their data. It’s like giving them the driver’s seat, and who doesn’t love a little control? Plus, being transparent about how you use their data is paramount. Clearly communicating how subscriber data is utilised and safeguarded fosters trust and strengthens the relationship between your brand and your audience. 

Remember, it’s not just about compliance—it’s about building a genuine connection. When your audience knows you’re handling their data responsibly, they’re more likely to engage with your content and stay loyal to your brand. So, make transparency your mantra and watch as trust and engagement grow.
