The Numbers

According to a study by Radicati Group, we're sending and receiving a whopping 293 billion emails per day in 2019. And it's only going to get crazier - by 2023, that number is expected to hit 347 billion. That's a lot of "you've got mail" notifications!

Business vs. Personal

Of all those emails, around 131 billion are business related and 162 billion are personal. So, next time you're scrolling through your inbox at work, just remember that you're not alone - everyone else is drowning in emails too.

Environmental Impact of Email Usage


Email has become an essential tool for communication in the modern world, with billions of emails sent and received every day. However, the production and usage of emails can have a significant impact on the environment. In this article, we will take a look at the environmental impact of email usage and what can be done to minimize it.

Carbon Footprint of Email

The production and usage of emails results in the release of greenhouse gases, primarily carbon dioxide (CO2), which contributes to climate change. According to a study by the Carbon Trust, the average email has a carbon footprint of 4 grams of CO2. With billions of emails sent and received every day, the carbon footprint of email can be significant.

Energy Consumption of Email Servers

The energy consumption of email servers is another major contributor to the environmental impact of email usage. Email servers require a significant amount of energy to operate, and this energy is often generated from fossil fuels, which releases greenhouse gases. According to a study by McKinsey, the energy consumption of data centers, which includes email servers, is expected to increase by 12% annually.

E-waste and Recycling

The production and disposal of electronic devices, such as computers and smartphones, also contribute to the environmental impact of email usage. These devices often end up in landfills, where they can release harmful chemicals and toxins into the environment. Additionally, the extraction of resources required to produce these devices can also have a negative impact on the environment.

What Can be Done

There are several actions that can be taken to minimize the environmental impact of email usage:


Email usage has a significant environmental impact, primarily due to the release of greenhouse gases and the energy consumption of email servers. However, by taking actions such as using energy-efficient servers and reducing the number of emails sent, we can minimize this impact. It is important for individuals and businesses to be aware of the environmental impact of email usage and to take steps to reduce it.

The Lowdown on Spam

What's the Deal?

We've all been there - scrolling through our inboxes and getting bombarded with unwanted messages. Spam emails can be a real pain, not only cluttering up our inboxes but also potentially carrying malware and scams. But just how big of a problem is spam, really? Let's dive in.

The Numbers

According to a study by Statista, around 45% of emails sent in 2021 were spam. That's a whole lot of "Congratulations! You've won a million dollars!" and "Limited time offer!" messages clogging up our inboxes.

Types of Spam

Spam can come in all different shapes and sizes. Some common types include:

The Source

So where do all these spam emails come from? Unfortunately, a lot of it is sent by automated programs called "spambots". These programs can scrape email addresses from websites and then send out messages to all of them. Some spam also comes from people deliberately sending out unwanted messages, whether for financial gain or just for the fun of it.

What Can We Do?

Dealing with spam can be a bit of a pain, but there are things we can do to help reduce the amount we receive:

Wrapping Up

Spam emails can be a real nuisance, cluttering up our inboxes and potentially carrying malware. But by being aware of the types of spam out there and taking steps to block or report them, we can help reduce the amount we receive.
