by Darina Lynkova

Walt Disney once said: If you can dream it, you can do it.

And many great people did dare to dream in the last 100 years!

It is an age of miracles, don’t you think?

Microsoft, Apple, Google, Tesla… not unlike Mickey Mouse, they became a worldwide phenomenon and game-changers in their fields.

Now, not so many years ago people rode on carriages and wrote letters with quills.

Today the basics remain, but the mediums have changed.

Visionaries dreamed and letters evolved into emails.

Today we shine a spotlight on the question:

How many emails are sent per day?

How about we warm up with some global email statistics:

Alright, so…

How many people use email in 2019?

There are approximately 3.7 billion email users in 2019. There are a lot of alternative means of communication today, but email is still the most popular.

How many emails are sent out per day?

Now, that is a question with a few caveats. We’ll explain those in just a bit. Read on and see for yourself.

Emailing statistics these days are quite staggering!

Let’s turn our email counter on and get started.

Still, for the time being, no platform stands a chance of dethroning email.

2. By the end of 2023, the estimated number of active email users is going to be 4.4 billion.

And since we can’t talk of office discourse without including the Slack stats for comparison…

In 2019, Slack has around 10 million daily active users.

Email still rules supreme.

(Imagine a horror movie with a working title “How Many Emails do I Have?” You wake up one day and discover that your inbox is the only one in the world. No one else receives any emails. You open it and there are 293.6 billion unopened messages. Goosebumps!)

If 293.6 billion seems a lot, brace yourself:

5. In 2023, more than 347.3 billion emails will be sent daily.

Yes, it is a lot! But think about the role of spam messages in all this. We’ll get to that in a moment.

Now that we covered the basics, we can go deeper to the darker side of email.

Spam and Email Marketing

There are lots of creatures that roam the realm of email statistics. Some of them are hiding in the dark corners and occasionally wreak havoc, others can make it rain.

Let’s have a look at.

The Giant Ogre that Is Email Spam

Unsolicited commercial emails, a.k.a. spam, are the worst!

It’s like a mosquito – no one thinks about it until it bites you and… well… you know.

Alright, so what qualifies as spam and what to be on the lookout for?

Let’s see:

  • If they offer you something in exchange for seemingly nothing – it could be spam!
  • If they are asking you some personal financial information – spam! There is a difference between offering financial services (which can be legit), and asking you for your bank account number.
  • If they are asking you to keep something a secret – spam!
  • Adult content – highly likely to be spam!
  • Info on the stock market you never asked for – spam!

What Are Malware and Phishing?

Malware spam messages contain software that is designed to take over your computer. Once the device is compromised, it can start sending out malware spam messages on its own.

Phishing attacks are designed to steal a set of credentials you own. They do so by creating a copy of a website you trust. If you land there and try to log in, you essentially hand your credentials over to the perpetrator of the attack.

Then they can use those to assume control over your real account – this includes social network profiles, email, and even your online banking account.

Protect yourselves and your data, guys!

Now:

How many spam emails are sent per day?

13. According to Statista, 55% of all emails are spam.

(Source: Statista)

Think about the implications of that number on a global scale. (293.6 billion emails sent per day in 2019!)

That’s roughly 107 billion spam emails per day.

What’s the most popular kind of spam emails?

14. 26.6% of all spam emails sent in 2017 were healthcare-related.

Yes, dating sites can be cunning. You don’t need to click on those troublemakers to know what awaits on the other end of the link.

According to spam statistics:

15. 14.36% of all spam in 2018 came from China.

(Source: Statista)

China is mass-producing everything these days.

Just be on the lookout for those Chinese characters and you’ll be fine. The ones in English are actually more subtle and need more attention.

Fun fact about spam:

On May 1, 2019, email spam will celebrate its 41st birthday. No cake and candles, though!

Email Marketing

Email marketing is easily the marketing channel with the best ROI. Lots of us nowadays are comfortable shopping online – and marketing emails can give us just the information we need.

In the pre-responsive era, we had to adjust our screen to every image and piece of content (not to mention in those days the internet was way slower).

Email marketing will definitely help your business grow!

Visual Email Trends in 2019

The next step in the email’s evolution is through new content types.

Personalization, interactivity, and creativity become the biggest assets when you want to attract the user’s attention.

The formula includes – more images and interactive content.

Let’s have a look at what’s fashionable in the realm of emails in 2019:

Emojis

Millennial culture has left its mark on what an email looks like nowadays. You can’t escape those emojis, GIFs, and video backgrounds – they’re everywhere. 

Our obsession with images today has brought us a tad closer to the culture of ancient Egypt and modern Asia. Those guys love bright colors, websites full of content, links, images, and videos.

It was actually a Japanese UI designer, Shigetaka Kurita, who invented emojis and revolutionized texting.

This happened way back in 1998, by the way.

Using emojis in email subject lines and content (which leads to increased open rate), is totally new, though!

18. Emails with emojis have increased by 775% from 2015 to 2016.

Emojis are everywhere and are becoming more and more popular… oh well.

By sending such emails, you also get a higher response rate. Additionally, an emoji makes your subject line shorter, which is a welcome bonus as any marketer will tell you.

Did you know that in 2011, Apple released iOS 5.0 and it was the first one to support emojis?

20. 87% of marketers plan to invest more money in email marketing.

Email marketing will become even more popular in the future. It truly is a gold mine for marketers!

APNG and GIFs

Animations can personalize your message further. As such, they’re definitely a type of content to experiment with in your campaigns.

21. 10.6% of all emails contained GIFs in 2016.

(Source: Templafy)

GIFs are a great way to stand out from the crowd as it is still underutilized.  

One caveat, though – be aware of the size of your GIF before you send out emails to customers. They can get really heavy and if your GIF loads slowly, it can leave readers with a negative impression on your company.   

Video, Video, Video

Videos can be a more effective way of communicating information for some types of people. And they are fun!

You can either embed a video in your email or use a static image with a play button that directs to the video.

Easy-peasy!

According to statistics:

22. In 2019, if you include a video background in your website design, you improve your conversion rate by 138%.

(Source: Website Builder Expert)

Moving pictures attract attention for a reason. Your email campaign will instantly become better once you add one to your website!

23. Including a video in your email boosts open rates by 19%, click-through rates by 65%, and it will reduce unsubscription rates by 26%.

Take advantage of that info right away and see the results for yourself. You’ll thank me later.

OK, what else?

AMP in Gmail

Now, that’s pretty cool!

In March 2019, Google launched a new feature for Gmail. It’s called AMP, which stands for Accelerated Mobile Pages.

It will enable users to stay in their email while browsing other pages. You will be able to make changes in real time, without leaving your inbox.

Imagine being able to complete an assignment, book a restaurant, or fill out a questionnaire, all from the convenience of your Gmail inbox.

Well done, Google!

Fun Facts

Moving away from serious business, let’s have some fun facts for a change, shall we?

Email is older than WWW

Email was invented by Ray Tomlinson and although it was very limited in the beginning, people have been using it since the 1960s.  

That’s all very cool, but did you know that the World Wide Web was invented in 1989? That’s right – almost two decades after the email.

The first web browser was launched in 1990 in Geneva, Switzerland, and boy, did that change things!

The symbol @ weighs 25 pounds

Before it was adopted by email, the at symbol was featured in three different languages – Spanish, Portuguese, and Italian. In the 16th century, the first two cultures used to signify the word arroba – which was a unit of weight that equaled 25 pounds. Some South American countries use it to this day.

The Italians also used it – again as a unit of measure. This time it represented an amphora or a standard measure for wine.

Oh well, times change.

Email in Real-life Interactions

The email has left a mark on everyday interactions as well.

24. 17% of Americans check their emails during a conversation.

(Source: Statista)

Our 24/7 access to email, while useful, has become a distraction for some.

13 and Suddenly…Gmail

You have to be at least 13 to register for a Gmail account.

Why 13? Isn’t 12 or 14 better? Apparently, 13 is the email’s coming-of-age time.

(Jeez, even Stephen King himself says he is terrified of the number 13! And if the King of Horror says he’s afraid of something…)
