Have you been using the same email client for a while and looking for a change? You’re not alone. Today, we’re reviewing all of the most popular email clients and checking out their features to give you a comprehensive list of the best email clients.
The average office worker sends approximately 40 emails per day. That’s a staggering 10,400 emails in a year. Choosing the right email client can result in much faster email responses, allowing you to spend more time on productive tasks. However, not all email clients are made the same, and some have more features than others.
Here’s a list of the best email clients you can download and install onto your Windows or Mac workstation.
1. Outlook

Microsoft Outlook is the standard of email clients by which all others are measured. It has been around since 1997 and is still the go-to by most businesses today for good reason. Right off the bat, Outlook’s calendar feature allows you to keep track of important events and tasks that need to be done. You can of course schedule appointments and meetings with it as well.
As for email management, it gives you the ability to categorize emails according to your labels and easy to follow color coding. It also allows you to create and rename folders that will help you organize emails better. Pair this with its effective filter system and you can easily locate any email or file. You can even set keyboard shortcuts for your most-used functions to make things smoother. In addition to this, Outlook also comes with a slew of complimentary applications courtesy of Microsoft 365.
Pros:
- Includes a lot of features
- Integrated calendar and contacts functions
- Customizable user interface and shortcuts
- Web-based and installed versions
- Secure and Reliable
Cons:
- Not the most intuitive email client with its cluttered user interface (Windows)
- HTML email signatures have formatting issues (Windows and Mac)
- Most expensive email client (the annual commitment clause turns monthly subscriptions into yearly ones and also charges per user)
2. Mailbird

If Outlook is the first among email clients, then Mailbird is a close second (though only available for Windows). Although it may lack its own integrations, it more than makes up for it through multiple third-party app integrations which include Facebook, Twitter, Whatsapp, Dropbox, Google Calendar and so much more. It also has one very important feature that few others have: multi-language support.
Mailbird said it best “We currently support 17 beautiful languages from all over the world.” But the most intriguing feature that this email program has is the ability to customize its user interface. It may not seem like much but it just screams “user-centric” and who does not want that? Being a user-focused email client makes it great for just about anyone.
The best part? Our email signature generator works flawlessly with Mailbird which is a huge bonus!
Pros:
- Simple and intuitive
- Various third-party app integrations (though limited for Mailbird Personal)
- Customizable and user-friendly interface
- Has a “Pay Once” option (Mailbird Personal)
- Live chat support through Skype (Mailbird Business)
Cons:
- Utilization of some third-party apps may make it look unprofessional
- Support prioritizes Mailbird Business over Personal
- No version for Mac (yet)
3. eM Client

If you’re looking for an email app that is not overly complicated or cluttered but reliable then eM Client might be a perfect fit for you. It has its own calendar and task management feature which helps keep track of events and tasks. Its integrated chat allows easy communication and conversations. Contacts have personalized avatars to help easily recognize senders/recipients. You can also take down important points or ideas through its notes feature. It can even translate incoming and outgoing messages from 39 languages.
Pair these with a simple yet familiar and customizable user interface as well an automatic back-up tool, and you have yourself an email client all contained in a well-designed package. What’s more, it has a FREE (albeit extremely feature-limited) version and you can get the premium version for a one-time payment. Amazing!
Pros:
- Compatible with all commonly-used email services
- Integrated features for easy access
- Ability to translate incoming and outgoing messages

This is further reinforced by having all of its functions integrated into a single application making it very easy and hassle-free. You can chat (individual/group), take calls, create docs/notes that you can share, use the built-in calendar for schedules and meetings, and task management for better workflow.
You can also change how your inbox presents emails: People mode which is by contacts, Inbox mode similar to traditional email clients, and Subject mode which is sorted by subject line. Probably the most unique feature of Spike is that it does away with repetitive elements and presents email messages like conversations.

With its quick filter toolbar and indexing function, you can search your emails using words or by timeline.
Its tabbed email feature allows switching between emails with ease. It also has Smart Folders which combines your Inbox or Sent folders and eliminates the need to access each of those in different accounts. However, one of its most unique features is its selection of add-ons which allows it to be customized to meet any user’s needs without the clutter that other email clients have.
