You put time, effort, and budget into your email campaigns. But how do you know it’s paying off?

That’s what email marketing ROI (return on investment) tells. It tells you how much value your emails generate for every dollar you spend. This helps measure success and make smarter marketing decisions.

In this article, we will explore the most recent email marketing ROI statistics to help you optimize your email campaigns accordingly.

Email Marketing Stats

Email is far from dead. In fact, it’s growing fast.

In 2024, people sent 251,100,000 emails per minute, more than any other communication method, such as instant messages or calls. This makes it super clear that email is still one of the most popular ways we communicate.

So, it’s no wonder that email marketing remains one of the most cost-effective tools for businesses.

But is it paying off for you? To know this, calculate your email marketing ROI.

Here’s how the math works:

ROI = (Money Earned – Money Spent) ÷ Money Spent × 100

Let’s say you spend $100 on an email campaign and it brings in $4,200. That’s a 4,100% ROI; you’ve earned 41 times what you spent. Pretty amazing, right?

So let’s look at some recent email marketing statistics to see how things have been going:

• On average, businesses make about $36 for every $1 they spend.

According to Statista:

• 57% of UK marketers say email marketing gives a good or excellent ROI
• 73% of in-house marketers agree
• And 75% of agency marketers back that up

• Companies around the world spent about $8.3 billion on email marketing in 2023.
• Fast forward to 2028, this is expected to hit $18.9 billion. That’s almost double in only five years, with an average growth rate of nearly 19%.

Email marketing is also ranked as the most profitable digital channel for good reasons, as compared to other marketing channels.

• 42% of marketers say email is their most effective channel, far ahead of social media and paid search, which both sit at just 16%.
• In 2024, 50% of consumers said they purchased directly from an email; more than from social media posts or ads.

So, for many businesses with good subscriber lists and strong email marketing strategies, email marketing delivers the highest ROI by far.

Global Email Marketing ROI Stats

A lot of businesses are already investing in email marketing. Let’s look at some data to understand its worth on a global scale:

• In 2020, global email marketing was worth $7.5 billion.
• By 2027, it’s expected to hit $17.9 billion, which is clear proof that more businesses are investing in it because it works.

As investment grows, performance also improves:

• In 2024, about 33% of marketers said their email marketing results were twice as good as the previous year
• Another 13.7% saw three times better ROI
• But it’s not all sunshine: 23.3% saw no improvement in ROI at all

Another thing that’s shaping email performance is the devices people use to read those emails:

• As of March 2024, more than half of all global email opens, about 55%, came from Apple devices using Mail Privacy Protection (MPP). MPP makes it harder for marketers to track user behavior (because of privacy!)
• Gmail came next, with roughly 30.57% of opens
• Outlook followed at around 4%

Email Usage Stats

One reason email marketing delivers such a strong ROI is simple: people use email most of the time. So, the more active users there are, the more chances you have to reach, engage, and convert them.

Here are some recent stats that show how widely email is used today:

• In 2023, there were about 4.37 billion email users worldwide, and that number is expected to grow to 4.8 billion by 2027.
• In 2025, 376.4 billion emails are expected to be sent every day. This is expected to reach over 408 billion by 2027.
• About 93% of people use their email every day, and 42% check it three to five times a day.
• 58% of users say email is the first thing they check online in the morning, so a well-timed email can be the first message they see all day.
• 60% of consumers prefer to be contacted over email by businesses.
• In 2025, Apple Mail holds the largest email client market share at 51.52%, followed by Gmail at 26.72%, and Outlook at 7.06%.

Email Engagement Stats

At the end of the day, sending emails is the easy part. The real challenge is getting people to actually engage with them—open them, click, and (hopefully) do what you want them to do.

Let’s look at some statistics related to email engagement:

Email Open Rates

Open rate is the percentage of people who open your email after it’s delivered. It shows how good your subject line is and whether your audience is interested in what you’re sending.

• In 2025, the average open rate across industries is about 42.35%. This shows that people are still paying attention to emails.
• A good email open rate in 2025 is above 30%, with 45-50% being strong, and over 50% being exceptional.

Click-Through Rates (CTR)

Click-through rate (CTR) shows how many people clicked on something in your email, like a link, button, or product. It tells you how interested your audience is in what you’re offering.

• On average, the email click-through rate across all campaigns is about 2%. Depending on the industry, this number can range from 0.77% to 4.36%. So while results vary, you can still get strong engagement if you’re reaching the right people with the right message.
• The design of your email also plays a big role. Emails with images get about 4.84% CTR, compared to just 1.6% for text-only messages.

Conversion Rates

Conversion rate tells you how many people take action after getting your email, whether that’s making a purchase, signing up for something, or filling out a form.

While ROI shows how much value you’re getting from your email spend, conversion rate shows what’s driving that value.

If your conversion rate goes up while your budget stays the same, you get more results without spending extra. That means your ROI improves; each result costs less. But if conversions drop, you’re paying more for each one, which can drag your ROI down.

Here are some supportive data points that you must know:

• In 2024, global data showed that automated welcome emails in e-commerce had a conversion rate of nearly 3%.
• But automated cart abandonment emails weren’t far behind, at around 2%.

• In 2024, email campaigns saw a 27.6% rise in click-to-conversion rates.
• With a conversion rate of 0.30%, the gaming industry was the highest converting industry in 2024.

Bounce Rate

Bounce rate tells you how many of your emails never actually reach someone’s inbox. It’s a signal of your list quality and can affect your ability to reach people in the future.

There are two types:

Hard bounces: Permanent delivery failures, often due to invalid email addresses.
Soft bounces: Temporary issues like full inboxes or server problems.

In 2024, the average bounce rate across all industries was 2.33%. A bounce rate below 2% is generally considered acceptable, and under 1% is ideal.

Unsubscribe Rate

When someone unsubscribes from your emails, it never feels great. 43% of people unsubscribe because they feel they get too many emails from the same sender. But it’s not always bad; it can actually give you helpful feedback about what’s working and what’s not.

As long as your unsubscribe rate is under 2%, you’re within normal industry standards. Most marketers aim even lower. The average unsubscribe rate is around 0.17%.

If your unsubscribe rate is higher than that, it means you should consider:

• Changing how often you send emails
• Improving your content
• Making sure you’re targeting the right audience

Sometimes people just get tired of emails over time, but other times it’s a sign your emails aren’t quite connecting. So monitor your unsubscribe rate and see how you can stay on track.

Strategies to Enhance Email Marketing ROI

Here are some actionable tips to improve your email marketing performance:

Personalize Your Emails

People are more likely to engage when the content feels relevant. Emails with personalized subject lines are 27% more likely to be opened.

Implement Automation

Automated emails, such as welcome messages and cart abandonment reminders, can boost your ROI. In fact, automated emails generate 320% more revenue than non-automated emails.

Optimize for Mobile Devices

You must optimize your emails for mobile devices, as 64% of emails are opened on mobile devices. And emails that aren’t optimized for mobile are often deleted within seconds.

Conduct A/B Testing

Testing different elements of your emails, such as subject lines and call-to-action buttons, can show better performance. To do so, use the A/B testing method. It can increase email marketing ROI by up to 83%.

Brands that A/B test every email see email marketing ROIs that are 37% higher than those of brands that never include A/B tests.

Maintain a Clean Email List

Regularly update your email list by removing inactive subscribers to improve deliverability and engagement rates. A clean list ensures your emails reach interested recipients.

Optimize Sending Frequency

Send too many emails, and you may annoy your audience (hello, unsubscribes!). Send too few, and they might forget about you altogether.

To avoid both situations, test and see what works best for your audience, because when you get the timing right, open rates and clicks tend to follow. 5-8 emails per month frequency has shown the highest ROI, about $48 for every $1 spent on average (for specific industries like consumer goods and retail).

Small improvements like these can give profitable results and returns from every email you send.

FAQs

Can Re-engagement Emails Help You Get Better Results?

Yes, re-engagement emails are sent to people who haven’t opened or clicked in a while. They remind them you’re still here and may bring them back. This can turn inactive contacts into active customers again.

What’s the Difference in Performance of Email Subject Lines With and Without Emojis?

The difference is relatively small. Subject lines with emojis have only a 4.7% higher open rate and a 3.3% higher click-through rate (CTR) than those without emojis.

Is Spam Still a Problem in the Modern Workplace Email?

Yes, spam remains a persistent issue. In 2025, nearly half of all emails, around 160 billion messages per day, are classified as spam. Although modern filters block most of these, some still get through, which clutters inboxes and poses potential security risks like phishing scams.
