30 Email Spam Statistics to Know in 2025

How much junk are we really dealing with, what is the impact and what can we do about it? Spam is a huge problem, that’s only getting bigger. In this article, we’re going to look at the numbers behind it.

What is email spam, again?

Here’s a really funny story.

Email spam, also called junk mail, spam mail, or just “ugh, not again”, refers to unsolicited bulk messages sent via email. The name comes from a Monty Python sketch from 30 years ago, where the word “Spam” (a meat product) is repeated endlessly. Spam was named spam after a canned meat product. It fits!

Spam’s been around since the 1990s and, unfortunately, it's never really gone away. At one point, it made up 90% of global email traffic. That’s… kind of insane.

And while it’s easy to ignore the occasional “you’ve won a gift card” message, spam isn’t just annoying. It has real consequences:

• An average person can lose up to 3 hours a week just sifting through spam.
• It buries important emails and you might lose sight of what’s important.
• It’s dangerous. Phishing emails are getting so clever, even people in cybersecurity (myself included) have been fooled.

So if it feels like spam is getting worse, you’re not imagining it. Let's look at the numbers.

How Much Spam Is Being Sent Every Day?

This is where it gets ridiculous. In 2025:

• +45% of all emails sent daily are spam.
• The average user gets 1825 spam emails per year
• That’s about 14.5 billion spam emails per day, according to an estimate from 2023
• Some researchers suggest the real number of spam emails is even higher, maybe up to 73% of all global email traffic. Source: SpamLaws.com

Who are the countries sending the most spam? Where’s It All Coming From?

Here's a (slightly depressing) list of the top spam-sending countries as of late 2021:

1. United States – 8.61 billion spam emails/day
2. China – 8.53 billion
3. Russia – 8.09 billion
4. Brazil – 8.03 billion
5. India – 7.97 billion
6. Germany – 7.9 billion
7. Czech Republic – 7.83 billion
8. Poland – 7.77 billion
9. Bulgaria – 7.73 billion
10. United Kingdom – 7.71 billion

💡Even countries with strong data laws still crank out huge volumes of spam. It’s a reminder that legislation alone hasn’t solved this.

What Kind of Spam Are We Getting?

Not all spam is the same. Some are annoying, some are dangerous, and some… you can’t quite tell.

Here’s how it breaks down:

• 36% advertising-related (basic promotions, newsletters you never signed up for)
• 31.7% adult content
• 26.5% financial spam (loan offers, fake crypto tips, etc.)
• 2.5% outright scams or frauds

💡 Of that tiny 2.5% that’s actually scammy, 73% involve phishing or identity theft. It only takes one click and you can lose a lot of money, important data or, even worse, your identity.

How Do People Feel About Spam?

No one loves it. But some people just out right hate it and want to abandon email altogether:

• 52% of internet users say spam is a major problem for them.
• 53% of users said spam made them lose confidence in email as a communication tool, but that was back in 2005. It looks like we don’t really have a choice but to use email.

And What About Businesses?

Spam’s not just annoying for individuals. For companies, it’s a budget-sink.

• 52% of businesses now say reducing spam is their number 1 email-related goal
• Spam costs businesses $20.5 billion a year, according to The Radicati Research Group estimates
• The average employee loses 2 days per year sorting spam
• Each employee wastes around $1,934 annually in productivity because of spam, according to Nucleus Research

That’s a full laptop's worth of lost time. Every year. Per employee.

The Future Numbers of Spam Looks… Worse

Looking ahead:

• Within 4 years, spam volume could hit 58 billion junk emails/day.
• At that rate, it could cost businesses up to $198 billion annually.
• If it keeps rising? Experts estimate a potential $257 billion annual cost.
• In 2025, an estimated 3.4 billion phishing emails will be sent daily.

And more and more of them are using AI to sound convincingly human. It’s not just broken-English scams anymore. Some even mimic CEOs or colleagues.

Final Thoughts

Spam is one of the oldest internet problems—and still one of the worst.

Despite better filters, smarter tech, and tighter laws, the volume keeps growing. The scams are getting sharper. And public trust in email? It’s… shaky.

We’ve adapted—by using burner accounts, switching to apps, or just ignoring inboxes altogether. But the truth is: spam still costs us time, money, and focus.
