What is an Email Client?

Before jumping into details, it’s essential to know what an email client is? An email client is a program or application that lets you access your email service via the web or installed application in a human language interface. The most significant benefit of using email clients is their offline support. All email clients allow you to access your past email activities offline without the internet, even in the web version.

List of Best Free Email Clients

1. G Suite (Gmail For Business)

While there are thousands of email clients out there, but there’s no wonder that Gmail is the No #1 email client in the world. It’s not only the most used email client, but according to Forbes, Gmail is the 6th most downloaded application on Play Store.

We all know, Google owns Gmail and is maintained by Google itself. For those who use Google’s email service (@gmail.com), Gmail will work best for them. However, it lacks some features, such as the old version POP3, which sometimes causes failed synchronization.

But still, if you want fundamental features from your email service and, ironically, you’re not a tech master, then G Suite is best for you! The best thing is that Google owns it. Therefore, you’ll get excellent optimization with Google’s email service in G Suite.

2. Outlook

In the competition of Gmail, there’s another email client: Outlook. Outlook is the most used email client in Windows OS. The tower is owned and managed by Microsoft.

For those, who have Office 365 or use Microsoft’s email service for business purposes, Outlook will work best for them! Most businesses use Outlook in their companies. First of all, it offers all the advanced and up-to-date securities, such as the 2021 version POP3 infrastructure, so that the service will never fail during the synchronization of your emails. Secondly, it’s from Microsoft, the only tech giant that has never been accused of data leaks, compromised securities, etc.

The most highlighted pro of this email client is its AI algorithm that distinguishes which email is important and which is a general un-important email. It automatically sorts them in a dedicated column for your ease! Overall, if you use Microsofts’ email service, Outlook is the ideal email client for you! But it works great with any other email service as well!

3. AOL Mail

AOL isn’t the best for tech guys but is perfect for casual people. We know, most of our readers haven’t ever heard about AOL before. However, AOL was the first-ever company that offered email service and an email client. Moreover, it was the most used search engine in the 1990s as well.

There’s no doubt that AOL Mail is one of the most secure email clients on the internet to date. It offers all the essential encryptions, such as 64-bit encryption, while many other services use only 16 or 32-bit encryptions. Moreover, AOL is fully optimized with IMAP services. Its latest IMAP technology lets you view all your emails without downloading or creating any cache in your system’s internal storage and using your device’s CPU resources. If your email provider supports IMAP, all the processing will be done on the provider’s server.

Besides AOL’s great email client, they also offer their email service (@aol.com). Therefore, if you’re using AOL’s email, it’ll give you the best optimization. However, it’s still a recommended email client even if you use any other email service.

4. Thunderbird

Thunderbird email client is managed and owned by Mozilla, the same company behind the world’s 2nd most used web browser: Mozilla Firefox. It works as the best alternative to G suite or Outlook if you’re looking for an open-source email client.

Thunderbird is entirely free to download, and the installation is straightforward. Once the set-up is complete, you’ll notice that it offers you all the functions and features you can expect from paid email clients. However, one thing which is outdated in this client is its UI. Ironically, it looks like a 2010 Gmail, which was based on pure HTML. But still, the style of UI doesn’t matter in email clients.

However, what makes Thunderbird unique is its customizations. For example, you can install additional 3rd party add-ons to make your email handling easier and convenient. Moreover, Thunderbird also offers a different theme pack, including dark, light, jet black, etc. Talking about its primary services, it provides all the latest servers for IMAP and POP3 and is optimized for SMTP email services.

5. Spike

Spike is an all-in-one email client and has cross-platform support. It offers its installable application on Android, Windows, Mac, iOS, and Linux. Spike also provides a web version from where you can access the client anytime and from any device.

What makes the Spike highly useful is its advanced POP3 standard. Unlike G Suite, Outlook, or Thunderbird, their POP3 standard never fails during synchronization. Moreover, Spikes offers both IMAP and POP3 means. Therefore, the MTA-based emails will land up to 40% faster in Spike than any other email client.

Talking about its UI, it’s much closer to an IM application. Spike presents you the emails in bubbles that look like an IM, such as Messenger. This concept works best when you use your email for short conversations. However, you can change the theme to the regular UI. Moreover, Spike is 100% free, and there’s no in-service purchase. You can even create a group of up to 10 people, which works best when you need to send an email to your employees.

6. Mail (by Windows)

email client free

It all started from Windows 7 when Microsoft noticed that 50% of Windows 7 OS is used in offices and professional places. But, the operating system lacks an essential office feature that is important in almost every professional and business work: email client. Microsoft didn’t offer any stock email client in Windows 7.

That’s why in Windows 10, they offered a stock email client to users: Mail. It comes pre-installed in all Windows 10 versions and is operated and managed by Microsoft. It’s not Outlook; it’s an email client in which you can use any email service you want.

However, unlike the Outlook business, it lacks some features, making it non-recommended for companies and professional needs. However, still, it’s best if you want a simple casual email client in your Windows 10 operating system for everyday and personal use.

7. eM Client

eM Client has been in the market for over 12 years. It offers a vast range of customizations and all the essential email client features you can expect from a free email client.

Talking about email services, eM offers a dedicated optimization with Gmail, Outlook, and Yahoo email servers. Therefore, you’re going to get the same service as you get in the pre-installed clients of these services.
