Email marketing statistics

I got my first email address when I was around 12 years old. I used to love AOL’s encouraging “you’ve got mail” greeting, though my inbox was fairly vacant back then.

Flash forward to 2021 and, though I’ve been through 3 different personal email addresses (plus a ton for various places of employment and education), I am still an avid email user – just like 50% of the world’s population. That’s right, there are currently 4.3 billion email users in the world, making it a great way to promote your products and services!

Though marketing strategies have included many different tactics over the years (flyers, TV, cold calling, social media, video, Facebook ads, SEO optimized content, etc.), one thing is clear: email marketing remains one of the most important tools for businesses in 2021, and it’s likely to remain that way over the coming years.

Find out why below.

Email Marketing and why it's so Important

Further down you can find our top tips on how to get better conversion rates, but first, the all-important email marketing statistics:

Email Usage Worldwide

As I mentioned above, 4.3 billion people use email, and that number is set to grow to 4.48 billion users in 2024.

So what does that look like in emails? In 2020, 306.4 billion emails were sent and received each day. The figure is expected to increase to over 361.6 billion emails a day in 2024.

You might say “that’s a hell of a lot of spam people are receiving”, and though the US has 2529 current live spam issues, the marketing emails received are continuing to engage people and lead to purchases of products and services across all industries. You only have to look at the ROI for email marketing, which continues to grow.

Email Marketing ROI

When you only have a limited marketing budget, you need to be sure that the marketing strategy you employ is going to be profitable. Many marketers will test a variety of tactics before investing a large chunk of the funds into whatever works. Of course, every business’s strategy will be different, but one thing is for sure: email marketing will give you results!

The first email blast was sent in 1978 and it generated the company $13 million in sales. Pretty impressive, right? Though things have changed quite a bit since the seventies, with companies having to compete a lot harder for their customer’s attention (and their cash), the return on investment for email marketing is still sky high.

Email marketing ROI is now calculated at 4400%. That’s $44 for every dollar you spend on your email campaign. And the best thing is, you can start collecting subscribers and sending them emails for free!

So when people ask “Is email marketing dead?” The answer is a resounding no.

Email Open Rates

email open rates

Whenever we send emails out, we’re not doing it just for fun. We want people to open them, to read them, and ultimately to engage with them. That’s the whole point of email marketing – engaging with new and existing customers, either to keep our brands front of mind or to promote a new offer to them.

If no-one opens them, there’s no point.

It’s important to monitor these results to find out what’s working and what isn’t. One of the most important metrics in email marketing is the open rate. This tells you what percentage of subscribers contacted opened the email.

On average, newsletters should have a 15-25% open rate, though this depends on the health of your list, subject lines, and even the industry you operate in (more on that below).

Email marketing platform, GetResponse, found the following average results:

  • Welcome emails have an open rate of 82.21%
  • Newsletters have an open rate of 20.48%
  • Autoresponders have an open rate of 29.77%
  • Triggered emails have an open rate of 44.07%
  • RSS emails have an open rate of 26.78%

With these figures in mind, you can see just how important it is to create an engaging welcome email with a clear call-to-action. Nothing too salesy though – you don’t want to put them off!

Depending on the nature of your business, examples of an action for your readers could be to:

  • complete their profile
  • login to their account
  • read a help doc or guide
  • watch an explainer video
  • download content
  • make a purchase

Considering triggered emails have the next best open rate, email marketers will be wise to choose an email marketing platform with automation capabilities.

But how does the open rate vary between industries? You’d be right to think that those working in the retail industry don’t have the same kind of open rates boasted by the nonprofit sector.

Industry Open Rates

According to Constant Contact, these are the industry open rates as of October 2020:

Industry Open Rate Click-through Rate Bounce Rate
Art, Culture, Entertainment 15.95% 8.37% 7.25%
Consultant, Training 11.89% 7.70% 13.48%
Fitness/Nutritional Services 12.23% 7.18% 6.40%
Home & Building Services 18.67% 6.66% 11.69%
Marketing, Advertising, Public Relations 11.63% 8.80% 10.64%
Nonprofit 20.16% 8.73% 10.22%
Professional Services 14.64% 8.82% 14.33%
Restaurant, Bar, Cafe, Caterer 13.94% 5.25% 9.92%
Retail 10.68% 8.21% 6.18%
Salon, Spa, Barber 13.53% 4.58% 13.98%
Travel and Tourism 14.83% 5.19% 7.80%

As you can see from the table, having a good open rate doesn’t necessarily mean an equally good click-through rate. For example, those working in the marketing, advertising and public relations industry have one of the lowest open rates but benefit from one of the highest click-through rates.

Click-through rates are also a very important metric to track. After all, each email should have a clear call-to-action for the reader, and this metric lets you know if they’ve carried it out.

So how can you increase open rate, and what can you do to ensure people read, click and convert?

Does Personalization Make a Difference to Email Open Rate?

There’s always something a little exciting about seeing your name in your inbox. Has that brand personally emailed me? Is that offer exclusive? And while personalized subject lines are nothing new, of the data analyzed still only 16.75% were personalizing the subject lines.

So what difference does it make?

Open rates were definitely better. While non-personalized emails were opened by 19.57% of recipients, adding the customer’s name saw open rates increase to 20.66%.

The click-through-rate (CTR) was also slightly higher – 2.62% compared to 2.33%, while the click-to-open-rate (CTOR – the people who clicked through after opening your email) was 12.70% versus 11.92%.

But What if the Body of the Email was Personalized too? Does That Help?

If you can use a customer’s name in the subject line, it makes sense to do it in the body copy too.

31.93% of emails use personalized body copy – more than use a personalized subject line, and this leads to a 21.75% open rate compared to 18.77%. A good start.

The CTR is also higher, 2.48% versus 2.33%. But when you get to the CTOR, the improvements stop. Personalized body copy only sees a CTOR of 11.42%, compared to non-personalized emails that achieve a rate of 12.42%.

Do Emojis Improve Email Conversion? 

Emojis in email subject lines can help your message stand out in a typically monotone inbox, as is proven by their open rate of 20.37% compared to 19.73% when they’re not used. However, once the emails have been opened they don’t seem to make a great deal of positive difference.

The CTR of emoji emails is only 2.35% versus 2.38%, while the CTOR is even worse: 11.52% compared to 12.07%.

It looks like an emoji can help get your email noticed, but you need to do more than that to make sure it’s read.

Mobile Email Marketing Statistics

mobile email marketing statistics

42% of all emails are opened on mobile devices, showing that recipients are likely to be reading your emails on the go. This figure makes a lot of sense seen as 49% of all web traffic in the US was from mobile devices in 2019 – a lot of which I’d imagine were directed to sites via email marketing.

This should give you an idea of just how important it is to optimize your email campaigns for mobile and tablets. In fact, 42.3% of readers will simply delete non-optimized emails, which is obviously something you really want to avoid.

Desktop Emails are More Likely to be Opened Than Mobile 

Desktop emails far outperform the open rate of mobile equivalents, by 75.55% to 24.45%. It makes sense when you think about why. If your customers are sitting at their desktop, they’re much more likely to be at work – a situation where they’ll regularly open emails and be active online.

If they receive the email on their mobile, chances are they’ve finished work for the day and are sat trying to enjoy themselves. Your email popping up midway through their favorite TV show is unlikely to be met with a warm reception.

Write for Mobile First

Even though our data shows how emails are more likely to be opened on desktop, that doesn’t mean you should look to fill a desktop’s worth of space with content. Your customers are busy, they don’t have time to read huge chunks of text. If anything, they’ll skim your email to see if there’s anything worth looking at.

Writing for mobile forces you to use less text and clearer headings – both good practice for emails of any kind.

Make your headings easy to read and descriptive. Explain what the content below them is about, so if people are scrolling through, they can see it straight away.

Then keep your copy short. Data suggests that emails under 200 words long are most likely to be engaged with.

Email Deliverability

We carry out our own bi-annual deliverability tests on the most popular email marketing platforms. We found that email deliverability averages at 85.2%, meaning that 14.8% of all emails go missing or are caught by the spam filters.

Of course, this is an average and some email platforms see a greater proportion of their emails getting lost in the mail. We’d recommend keeping an eye on deliverability rates and carrying out your own tests.

Abandoned Cart Emails

Abandoned cart emails make you money. Fact.

Klaviyo, an ecommerce platform, carried out an analysis which revealed that abandoned cart emails could be highly lucrative. In the analysis, approximately 3,000 customers recovered more than $60 million in abandoned cart revenue in just three months using an abandoned cart email series. They also discovered that, on average, abandoned cart emails have conversion rates that are 3x greater than other automated workflow emails.

That’s pretty impressive, especially when you consider how little work it takes the marketer to set up. If you have an ecommerce this is something that you should be implementing yesterday!

Where are People Reading Their Emails?

Many people use software applications on their desktop, mobile or tablet to read, send and manage their email.

Popular desktop clients include Outlook and Apple Mail, and the most popular web-based email system is Gmail. Apple iPhone is the most popular reader used.

    Some email marketing platforms allow you to preview your email design on a number of different email clients. I would bear the above figures in mind when doing so, whilst also checking it against your own data regarding your subscribers.

Our top Tips for Email Conversion 

There’s no way to guarantee everyone will engage with your emails. After all, not everyone will be looking for what you’re selling at that exact moment, and no matter how you pitch it, they just won’t be keen.

However, there are simple things you can do to give yourself a fighting chance.

Timing is Everything

Have you ever noticed how fast food emails hit your inbox at around 17:30 on a Friday? That’s no coincidence. The brands know that’s when you’re most likely to be thinking about treating yourself, so they make it easy by hitting you with a discount code and pictures of your favorite curry. Email, opened.

Think about when you want to engage with your customers. When are they likely to want your product? When are they likely to be checking their emails? Chances are, their inbox will be full first thing in the morning. They’ll go through and clear anything out that doesn’t look important.

If your email lands later on in the day, seeing that little ‘1’ pop up in their inbox could be enough to grab their attention.

The research suggests that 21.49% of emails are opened within the first hour of them being received. Make sure yours has space to be seen.

Give Them a Reason to Read More

Your subject line is everything. If it’s boring, why should anyone read anything else? While personalization can help, an email that says, ‘Name, here’s our latest newsletter’ still isn’t going to get anyone’s heart racing.

Instead, target the subject line at their interests. Use your data to see what products they’ve been looking at, which deals they’ve been eyeing up, what buttons they’ve been clicking.

A subject line that says, ‘Hey Name, we’ve got an exclusive <product name> we think you’ll love’ is more likely to grab their attention. If it’s something they’re already looking for, they’ll appreciate you helping them find it.

Use pictures

Emails with images achieve open rates of 21%, compared to those without that achieve rates of 15%. Engagement is better too, with a CTOR of 12% v 10%. Images just make the email look more inviting. People are likely engaging with them during the working day or on mobile devices, meaning they don’t have time to read through tonnes of text. Text looks boring. It looks like hard work.

Adding relevant pictures in can break up the scroll and make your email marketing appear more professional.

Offer clear calls to action, often 

The main point of any email marketing campaign is to get customers to click.

Make it as easy as possible for them to do just that.

Clear CTAs that stand out from the rest of your copy are easier to spot, no matter how fast someone is scrolling. Put one in the very first section of your email, so people don’t need to read anything to complete the action, then stick a second right at the end.

Break your content up

Headers and sub-headers are essential for readability. Long blocks of content aren’t appealing and are impossible to read while scrolling. Headers give people something to look out for, allowing them to quickly scan your email and absorb all the information relevant to them.

Emails with headers achieve CTORs of 14%, compared to those without, which only achieve 11%.

Avoid clickbait headlines

Open this email, you won’t believe what’s inside!

That might have worked once, but anyone who’s had an email inbox since the 90s will know it’s a trick of the trade. Clickbaity headlines like this risk winding your audience up, so unless they genuinely WON’T believe what’s inside (flying dog, Eiffel Tower made of cheese, etc.) don’t bother.

If the body of your email is interesting enough, mention it in the subject line. People can decide for themselves if it’s worth clicking.

Don’t forget your tone of voice 

Emails are just another branch of your overall communications platform. If a customer reads an email and clicks through to a website that sounds nothing like it, they’ll be a little confused. At worst, they might think they’ve been scammed.

Write your emails just like you’d write anything else to ensure brand consistency.
