How Many Emails Are Sent Per Day? (2023–2027)
These days, email and work have become pretty much synonymous. This is so much so that your job scope, business, and industry don’t really matter, as sending and receiving emails are almost bound to be involved in one way or another.
To get a feel of how widespread email usage is, we first have to have an overview of how many emails are sent per day.
Number of emails sent per day: 2022–2026
According to recent data, worldwide, the number of emails sent and received per day in 2024 is 361.6 billion—a 4.1% increase from the previous year, when the number of emails sent and received per day registered at 347.3 billion. This figure is set to further increase by a similar margin in 2025, hitting 376.4 billion.
Despite the growing popularity of communication tools and top messaging apps like Slack and WhatsApp, it’s clear that email still features heavily in consumers’ daily lives. Even though experts had previously predicted that email would become obsolete by 2020, that’s hardly been the case.

In fact, the average number of emails received per day has been growing over the past few years and will continue to do so at least until 2027.
In 2017, experts estimated the number of emails sent per day was 269 billion. The latest research shows that by 2027, this number is projected to exceed 400 billion, to 408.2 billion. This marks a 51.7% increase in a decade.
This increase in email usage is in line with the growing number of email users globally. In 2024, there are an estimated 4.4 billion people worldwide using emails. This is forecast to increase to 4.8 billion by 2027.
Experts also attribute this to the growth of internet accessibility around the world, which has led to more and more internet users.
As an ecommerce business, emails should form a key part of your communication with your target audience. Not only is it low-cost, but it also allows you to reach them quickly and conveniently.
Whether you’re sending a welcome email, setting up a promotional campaign, or reminding buyers of their abandoned carts, engaging in email marketing provides plenty of benefits for businesses. It’s a great way to build and foster a relationship with your buyers, improve customer loyalty and retention, and eventually boost sales.
