Phishing is the most common type of email spam across the world. Phishing is where email senders distribute malicious emails for nefarious purposes.

Spear Phishing is known for being an attempt to get sensitive and confidential information, or access to a computer network/system through spam, counterfeit emails.

These emails appear to be legitimate, but the goal of the sender is to gain access to financial data. 

A whaling attack, also called whaling phishing, is a distinct type of phishing attack used to target an organization’s high-level corporate employees to steal company information.

These emails are commonly sent to chief executive officers (CEOs), or chief financial officers (CFOs).

It costs them nothing in terms of money, but they certainly don’t help CO2 emissions.

These emails appear to be legitimate, when they are spam and sometimes malicious. They are at least annoying. 

(Groupmail)

20. Over 99% of Spam Attacks Depend on Human Interaction to Be Successful.   

When it comes to succeeding as an email spammer, it takes at least two parties. The sender of the spam email and the person to click the spam link.

These professional spammers create tricky, very real- and important-looking emails. It’s up to up to recognize the intent behind such emails. 

It’s better to not click a link inside an email or message than to fall victim to malware.

It can be an email attachment that looks like it’s from work, or an official company, or a document or link that looks legit.

Being careful can save you and your company a lot of money.

Additionally, spam scams are also focused on acquiring LinkedIn (6%) and Amazon (5%) credentials.

FAQs

Can You Reduce Your Email Carbon Footprint?

You can reduce your email cardon footprint. We can’t just boycott email, but we can do a few things to help.

1. Delete unnecessary, unwanted, unused emails. Doing so will delete it from the server, which will emit less CO2 for storing them. 

2. Unsubscribe from any unwanted emails. While deleting them helps, unsubscribing to things you’re not that interested in permanently removes wanted emails. 

3. Regularly empty your email trash folder. Even though some email clients automatically delete trash emails after 30 or 60 days, you can help by emptying your trash emails more often. Daily, bi-weekly, or weekly.

4. Don’t send one-word or very short emails. Emails that just say “thanks”, “yes”, “sure”, or “will do” are not always necessary.

5. Turn off your social media email notifications. They are not necessary, and they increase the carbon footprint.

6. Set a goal to have an inbox of zero emails when possible.

7. Clean up email lists.

These are a few things you can do as an individual or business to reduce your email carbon footprint.

Why Is It Called Spam?

In 1937, Spam luncheon meat was introduced to the public. Hormel

Foods manufactured canned Spam, which was very popular on grocery shelves.

There are two trains of thought about how Spam became spam emails. 

1. This theory states that Spam comes from a meat substitute, which makes it a fake meat. This assumption isn’t true, but this is one theory of how it translated into spam, or fake emails. 

2. Another theory claims that spam emails came from a sketch from the Monty Python Flying Circus movie in 1970. The sketch shows a group of consumers singing and yelling about Spam as they drown out all other conversations in the skit. Somehow this represents how spam drowns out your real emails. 

We are not sure which theory is legit, but both could fit the concept of spam email.

Which Companies Send the Most Spam Emails?

There are three companies known for flooding the internet with marketing emails (spam).

These three companies include Goodreads, Live Nation, and StumbleUpon.

While these are the top three offenders, we also have Target, Old Navy, Groupon, and Bed, Bath & Beyond.

What Makes Spam Emails so Harmful?

Most of the time, spam emails are just a nuisance. However, about 2.5% of spam can be very harmful.

They may include phishing, malware, identity theft, or other scams that can do major damage to a person’s lifestyle and finances or a business’ finances.

If you read the whole article, you will understand its effect.

Conclusion

It’s common to get one or two spammy emails a day from legitimate marketing campaigns, even with spam filters on that cause no harm, though they are annoying.

However, without spam filters of some kind, you could be putting yourself and your computer or mobile devices at risk.  

Spam emails, phishing, malware, and other harmful attachments or links are sent out every day to businesses and individuals all over the world.

It’s crucial to have an antivirus with spam filters and updated malware protection to give you some peace of mind.

There seems to be a consensus among experts in cyber security and other fields of IT that spam emails will continue to rise, even with advanced technology to combat it in play. 

Now that you have the 2023 email spam statistics, how will you protect yourself?
