7 must-know email trends for 2023/2024

When it comes to email communication and especially email marketing, 2023 and 2024 are full of interesting trends.

Here are 7 exciting email changes you should consider adopting as soon as possible:

Trim down your subject lines

This year, digital marketers recommend writing extra-short, to-the-point email subject lines.

Think three words or less. So, for example, instead of writing “10% Discount Voucher on Hundreds of Items,” try “Special Discount Offer” or “Limited-Time Discount.” Remember: conciseness is key.

Personalize your email messages

When signing up for your email newsletter, your current and potential customers provide you with their personal info.

One of the reasons they do this is to help you create and share relevant and valuable content with them.

And that’s exactly what you should do - write custom emails for specific recipients based on their age, location, preferences, email behavior, purchase history, etc.

It’s important to keep in mind that email personalization goes beyond addressing your subscribers by name.

Make the important bits clickable

Your email recipients shouldn’t have to assume what you want them to do or where they’re supposed to click.

That’s why you should always make sure the crucial parts of your email copy are clickable. You should, of course, start with your CTA and social media icons.

Check out this guide on how to create clickable emails with the right design.

Optimize your emails for mobile

As mentioned above, a large number of email views come from mobile devices. This means that a huge chunk of your recipients open and read your emails on their smartphones.

That’s precisely why you should make your email marketing campaigns mobile-friendly.

Aside from using responsive templates, you can accomplish this by going easy with images, being efficient with your words, particularly in your subject lines and headers, avoiding long paragraphs, and using buttons for your CTAs instead of written links.

Add user-generated content to your email messages

2023 is the perfect year to start enriching your emails with user-generated content.

It’s a great way to show your customers you don’t take them for granted and that you care about their experience with your products and services.

There are many types of user-generated content to choose from, but two of the most effective ones are reviews from your customers and photos of them using your products and services.

Make your emails interactive

Interactivity is one of the most fun email trends in 2024.

You can make your email marketing campaigns more engaging and competitive by adding gamification elements and interactive sounds, incorporating polls, surveys, feedback forms, and quizzes, and including hover-over imagery effects.

Although animated GIFs are cool and popular, they’re not interactive as they’re viewed passively.

Include unsubscribe links both at the beginning and the end of your emails

Trying to keep your subscription list intact by hiding your unsubscribe links is so 2010. Such tricks won’t fly today. The smartest and safest approach is to make it obvious for your subscribers to opt out of receiving new email messages from you. Incorporating unsubscribe links both at the top and the bottom of your emails is the easiest way to do it.

Email statistics FAQs

What is the future of email?

The future of email looks bright. Experts predict that the number of global email users will increase to around 4.59 billion in 2025.

The number of sent and received emails per day is also expected to grow - to 361.6 billion by 2024 to be precise.

When it comes to email marketing, machine learning, and artificial intelligence are already making marketing automation a possibility and will give businesses the chance to create large email marketing campaigns without having to spend a lot of money.

Do email campaigns still work?

Yes, they do. Global email marketing revenue is projected to reach over 10 billion U.S. dollars in 2023.

Plus, email marketing’s average ROI is practically unbeatable - for every U.S. dollar you spend on email marketing, you can expect up to 45 U.S. dollars in return.

Email marketing campaigns work mainly because people prefer getting promotional messages in their email inboxes rather than anywhere else.

What are the 5 types of email?

The 5 most common email types are:

• Newsletter emails (emails sent to a list of subscribers to keep them up to date regarding your products and services or brand)
• Lead nurturing emails (emails sent to move leads from the consideration stage to the decision stage of the lead funnel)
• Promotional emails (emails that offer incentives to drive sales and revenue)
• Milestone emails (behavior-based emails sent to existing customers)
• Survey emails (emails sent to a target audience to gather information via surveys or questionnaires included in them)

Summary

The email has been declared dead many times.

However, if we take into consideration the number of global email users and the number of emails sent and received every day, it becomes clear that this communication and digital marketing tool isn’t a thing of the past.

The email is here for good.

The latest research shows that both individuals and companies rely on email to market their products and services and seal deals.

They will continue to use email for business purposes, but their success will depend greatly on whether or not they adopt the hottest trends and make the necessary adjustments.

These adjustments include personalization, interactivity, captivating storytelling, user-generated content, and, of course, data privacy.

Exciting times are ahead!
