13 Best Outlook Alternatives For Windows 10 2022

Outlook is a well-known email service that can easily manage your emails, calendars, and contacts.

It is easy to integrate with Word, Excel, and PowerPoint. It also helps to scan and remove malicious attachments.

The app is great for professionals who need to access documents from the cloud and send back updates in real-time.

However, not everyone needs all these features that come with Outlook or is a fan of its email service.

This is because, as good as Outlook may be, it has its limitations such as complex password recovery, slow performance, and lack of integration with Google Drive.

Luckily, if you are looking for alternatives that will work seamlessly on Windows 10, then you have come to the right place. Here is a list of some great Outlook Alternatives:

Best Outlook Alternative for Windows 10

1. Mailbird

Mailbird is a free email client for Windows that provides an outstanding user experience with its modern and sleek design. It also won the “Best of 2015” award from PC Mag.

The company’s headquarters is located in Palo Alto, with its whole development located in the US.

While Mailbird is free, it also has premium features like multi-account support and email delegation (e.g., assigning an assistant to check your mail on your behalf).

It is easy to use and allows you to connect your Gmail, Yahoo Mail, Outlook/Hotmail, AOL accounts as well as many other mail services via IMAP.

Mailbird also comes with an integrated address book, calendar, and file-sharing feature.

Mailbird takes the style of desktop Outlook and combines it with the ease of use and simplicity of Gmail.

It comes with a full set of functionalities that are common for desktop clients including customizable swipe gestures or chat capabilities via Slack integration.

In addition, it also offers a free email backup service and file sharing with Dropbox.

Mailbird is compatible with Windows, Mac, and Linux operating systems.

2. Thunderbird

Thunderbird is an open-source and free email client that is available for all major operating systems.

The interface of the application has a traditional look, just like Outlook Express used to have before Windows XP.

However, there are also visual elements from Gmail or Yahoo Mail included in its design as well.

Thunderbird supports POP and IMAP protocols for receiving emails. It also supports SSL/TLS encryption for your data.

The application can synchronize mail between devices with the use of IMAP IDLE.

If you are using more than one device then this is a useful feature that Outlook does not have to offer its users at the moment.

You may access Thunderbird by downloading it from the Mozilla website.

It is only available for Windows and Linux operating systems. For Mac, it comes in a separate version, named Seamonkey.

The Mozilla Thunderbird interface has several options that help users organize their messages better.

You can create folders to store your emails or move them between existing ones if required.

There are also filters that allow you to define actions for messages that would match certain criteria, e.g., you can move all personal emails to a separate folder or delete them directly in the inbox.

The application offers several special compartments for organizing your contacts (including address books) and RSS feeds separately from other email folders.

It is also possible to use canned responses when composing new mails, which speeds up the process.

3. ProtonMail

ProtonMail is a well-established secure email service that has been around since 2013.

It offers a number of features, but one unique feature is its “Zero-Knowledge” policy which means that your data and messages are encrypted at all times.

What’s unique is that even the company cannot decrypt them if they were to be made available to law enforcement agencies.

ProtonMail also uses PGP which is a method of encrypting and decrypting email, so if you are sending an email to another ProtonMail user it’s already encrypted.

It also offers apps for Android and iOS. If you want more information on how this works then check out their Guide.

ProtonMail also offers more features, although its user interface is not as nice and polished looking compared to Outlook, that might be because you are used to using another email service like Gmail or Yahoo. Mail which looks different.

Some of the best features of ProtonMail include its ease of use, encryption, and security features.

Also, it’s a service made in Switzerland which means you do not have to worry about the NSA spying on your emails since they’re located outside of US jurisdiction.

It also comes together with other services like ProtonVPN for free so you can browse anonymously online or encrypt your internet connection when using public WiFi hotspots.

It’s also very easy to set up and use, all you have to do is just enter your email address and password then you’re done.

It even works on mobile devices so that means you can access your emails anywhere at any time with no hassle.

You could even set up ProtonMail Bridge for Mac or Windows to make your emails available on your computer.

4. Spike

If you think Outlook’s UI is cumbersome, Spike is an alternative for you.

The service has a very simple interface that only shows the sender and subject of each email message.

It also does not show any ads which are always great to see, but its functionality ends there as this app lacks many basic features like multiple account support or filters.

The free version comes with one year of full access to the service. After that, you will have to pay money for each additional year of access which is pretty pricey considering there are better options out there.

Spike has some good features like sending your email via SMS or emailing USB sticks directly from the app but it’s impossible to recommend this alternative because its price and basic functionality make other apps a better choice.

The app has a huge list of features that make it one of the best Outlook alternatives which include:

• Ability to send email via SMS or USB sticks
• Personalized replies and canned responses
• Email tracking and optional read receipts. Automatic image resizing for attachments in your inbox, sent items and draft folders so you don’t have to do it manually anymore.
• Open multiple accounts
• Create and manage folders
• Organize contacts into groups, view group member details, and send messages to a group of recipients at once with BCC functionality

5. Simple Mail

If you don’t need all those advanced features then Simple Mail is your choice as it’s free, easy to use, and it’s completely offline.

It supports both POP-based accounts as well as IMAP ones, has a simple user interface that is easy to use even by beginner users.

It lets you send emails in plain format or HTML one, automatically saves sent messages into your drafts folder for future reference again without requiring an Internet connection at any point in time.

It doesn’t have any spam protection feature but it does let you preview your email before sending it, which is definitely helpful for the user to view how their mail will appear once sent out.

It requires Microsoft .NET Framework v20 or a higher version on your PC to install and run this software program without any problem.

Like Outlook, it also lets you connect to multiple email accounts in one go.

It’s open-source software that has many hidden features and customization options available for the user if they are willing to look for them.

Its best feature is its clean, simple but effective interface without any clutter of ads or other unnecessary tools or objects on your screen when you install it.

eM Client will keep your information secure by encrypting all the data in transit with SSL/TLS connection or SFTP protocol (for IMAP accounts).

You don’t need to worry about the security of your account, because the data is stored on your computer and not online.

Other top features of eM Client include but are not limited to:

EssentialPIM is a free open-source alternative to Outlook.

It is cross-platform and can be synced with Google Calendar, Thunderbird, and more.

EssentialPIM has many features that Outlook does not have including a built-in password manager, a to-do list, and the ability to encrypt your emails.

EssentialPIM is not as user-friendly as Outlook but it does have very good features for those who are looking for a replacement.

One slight inconvenience would be that EssentialPIM is only free on PC and Mac computers because there is no mobile version.

Also, EssentialPIM does not have a calendar like you would find in Outlook.

It was developed in 2007 and has been growing ever since with updates coming out every few months.

Another great thing about EssentialPIM’s updates is the fact that they add translations of their software, such as French and Italian.

One of the best things that EssentialPIM has going for it is that it is very easy to learn with just a little bit of time spent getting used to where everything is located.

And of course, it has a great email tracking feature that will tell you when someone opens your message.

If somebody doesn’t reply to an important email for a long time, Polymail will also give you the option to send them reminders or follow-up messages.

There are many free apps that do this too, but most don’t have all of Polymail’s features, and the ones that do are not as good.

It is beautifully designed, even though at first you might think it looks a bit too simple.

Its key features are:

• Powerful search capabilities can find any message you need in seconds
• Send later option lets you schedule emails for delivery at just the right moment
• Get push notifications along with reading receipts so you never miss an email
