Basics

Despite many other digital means of communication we’ve got nowadays, email is still one of the most popular ones. In fact, the amount of global email users is quite staggering. According to Statista, in 2022, there were over 4.36 billion email users, and this number is growing every year.

💡 Whether you’re using email for personal or professional needs, choosing the right email client is key to effective and streamlined communication with your friends, partners, clients, and businesses.

In this article, we’ll review the 8 best free email clients with their features, pros, and cons. In the context of this article, the term “email client” refers to desktop-based and mobile-based email providers rather than the standard web-based ones you can access from any browser.

Why Do You Need a Free Email Client?

Chances are you’re already using an email provider. You’re likely using one of the best free business email like Gmail or Yahoo! Mail. What’s more, you probably didn’t even think about it much when you chose to create your email with one of these providers. They’re the most popular ones available on our mobile devices by default.

💡 But are they fulfilling your email needs, or are you just settling for the convenience of the default app or the email account you created 15 years ago?

If your current email provider isn’t providing you with a smart email experience that can help you make your communication more efficient, you may need to consider switching to a desktop-based email client.

A good free email client for both personal and business communication should:

Be easy to use with an intuitive interface
Be available to download and use on various devices (like desktop and mobile)
Offer a generous amount of storage for your emails and attachments
Offer access to other apps, like a calendar or a task app, for a comprehensive experience
Offer a unified inbox where you can connect multiple email accounts
