The number of email users worldwide is on a constant rise, and it doesn’t plan to stop soon. We’ve gone over some interesting email usage facts. We’ll show you why email marketing is important and how it can help you grow your business.

How Many People Use Email for Communication

The way we communicate evolves all the time. Messaging apps gain and lose popularity, video calls have become commonplace, and thanks to chatbots, we even communicate with algorithms pretending to be human beings.

However, one thing doesn’t change. Regardless of chat and video-call apps, email communication is ever-present and won’t go away anytime soon.
The number of email users constantly grows on a global scale, and experts predict that the trend will continue in the next few years. According to Statista, in 2025, around 4.6 billion people will use email.

What does that mean for your business? Every year, we have people claiming email will slowly die out, and reaching out via email will become relevant. Every year, they are proven wrong.

Email marketing is still one of the most prominent and efficient ways to generate and convert leads, increase engagement, and establish your brand. Global email marketing revenue in 2022 was $9.62 billion, and that number will reach $17.9 billion in 2027.

You can set up various email marketing campaigns to increase your sales significantly. However, running a successful campaign takes a lot of time and planning; doing it manually is a nightmare.

Interesting Email Usage Facts

Email marketing is not an easy marketing channel to master. Click-through rates of promotional and business emails are low, varying from 1.6% to 3.1% on average. Still, about 81% of businesses utilize email marketing to market their products and services to existing and potential customers.

According to Statista, the key objective of email marketing is to increase product awareness and offer promotions. The most popular objectives (with the percentage of marketers choosing them) are as follows:

  1. Product awareness and promotions: 63.49%
  2. Retention: 58.73%
  3. Acquisition: 57.14%
  4. Newsletters: 50%
  5. Transactional communication: 34,13%
  6. Surveys and data collection: 21.43%

Depending on the objective of email marketing and your business model, your approach to it needs to differ. A sent email can be the difference between a customer and a window shopper that doesn’t make a purchase.

Surveys show that the most popular campaign is a newsletter, followed by promotional and welcome emails. Check out the table below to see what campaigns marketers run most commonly:
