I appreciate the tip, but this doesn't appear to resolve my issue. I have confirmed that the default Email client is MS Outlook, but sending Email from within an application still chooses Mac Mail. Note In Outlook for Mac 2011 version 14.2.4 and earlier versions, data was appended to the same log file for every Outlook session. In Outlook for Mac 2011 version 14.2.5 and later versions and in Outlook 2016 for Mac, every time that you quit and start Outlook when logging is enabled, a new log file is created. Developed in 2006, eM Client is a Windows-based e-mail client with which you can send and receive e-mails, manage calendars, contacts, and tasks. The goal was to make it more user-friendly than other existing e-mail clients.

Every Mac comes with a free email application, appropriately named Mail. Using the native Mail application is fine for most people, especially for those who only use iCloud, but things get trickier when you’re dealing with multiple email accounts.

For Gmail users in particular, more thorough solutions are available, many which are free. Here’s a look at five Mail alternatives and why they might work for you.

AirMail ($10)

Marketed as being a “lighting-fast email client for Mac,” AirMail is also the most beautiful application on the list. Offering Split Screen support for OS X El Capitan, the application looks and feels like it’s an Apple creation. It also features some options not available on the native Mac application, which consistently makes AirMail one of the best overall apps for OS XThe Best Mac Apps to Install on Your MacBook or iMacThe Best Mac Apps to Install on Your MacBook or iMacLooking for the best apps for your MacBook or iMac? Here's our comprehensive list of the best apps for macOS.Read More.

Chief among this is the ability to compose in Markdown or HTML. As you type on the left, the result is shown on the right side of the screen. Being able to view the formats side-by-side means you can make sure to remove broken links or weird-looking text before sending.

In AirMail, received messages may be organized by task. You can mark each email as To Do, Memo, or Done. The first are for items that require some action or a follow-up. A Memo is for items you need to memorize or store for later, and you can mark completed emails as Done. You can also Snooze messages, allowing you to move them to the side for viewing at a later time or date.

The application offers support for Google, iCloud, Exchange, Yahoo, Outlook, AOL, IMAP, and POP. It also works with many third-party integrations, including Dropbox, Google Drive, OmniFocus, Things, and many more.

AirMail is available in the Mac App Store. You can also download a beta version for free from the developer’s website. An AirMail for iPhone app is coming soon.

Mail Pilot 2 ($20)

Like AirMail, Mail Pilot 2 turns mail into a to-do list, allowing you to focus on what’s most important. Unique to Mail Pilot 2 is a relatively new feature called Dash.

With Dash, your daily life is summarized on a dashboard to help you become more productive. It includes the number of messages that you have received in the past 24 hours, plus those that are completed, set aside, due, and late. Dash also summarizes the average time it takes for you to reply to emails and more. Another handy feature provides links to files that you’ve recently sent or received, which is very nice.

The application supports all standard IMAP accounts, including Gmail, iCloud, Yahoo, AOL, Rackspace, Outlook.com, and Google Apps. Mail Pilot 2 is available in the Mac App Store. A $9.99 iOS version is available from the App Store.

Postbox ($10)

Postbox is one of the oldest email clientsPostbox: An Alternative Email Client For MacPostbox: An Alternative Email Client For MacPostbox is an email management application for Windows and Mac powered by the Mozilla platform.Read More on our list, but it’s also a very stable product. Postbox’s goal is to remove some of the chaos associated with mail, by offering robust tools to make the process more efficient.

One of Postbox’s nicest features is the ability to group messages by topic. This allows you to break work into smaller, more manageable chunks. Grouping by subject is particularly useful when you have more than one email account. Postbox also enables you to create Pre-Made Responses, which you can reuse as often as needed.

Postbox works with most email providers including Gmail, Yahoo, AOL, and iCloud. It also supports POP3, IMAP, and SMTP protocols. It is available from the Postbox website. A 30-day free trial is also available, so you can try before you buy.

CloudMagic (free)

This mail client only recently arrived on OS X after finding success on iOS and AndroidTask-Oriented Email App Mail Pilot Arrives On Mac OS XTask-Oriented Email App Mail Pilot Arrives On Mac OS XLike the mobile version of the app, Mail Pilot for Mac is very useful for managing important email like a to-do list.Read More. Dubbed “simple, beautiful & blazing fast” by its creators, the application features a transparent user interface, free of fancy buttons or slides.

This approach works well, especially if you have to go through a lot of emails each day or have multiple accounts. We especially like the application’s shortcut buttons, which allow you to move quickly to the next or previous email.

CloudMagic offers support for Gmail, Exchange, Google Apps, Yahoo, Outlook, iCloud, and all IMAP accounts. It’s available in the Mac App Store. CloudMagic for iOS and CloudMagic for Android are also available. Both are free.

Nylas N1 (free)

Two of most popular third-party mail clients in recent years were Sparrow and Mailbox. After each was purchased by Google and Dropbox respectively, both were eventually shutdown, leaving millions of users in the lurch. By contrast, Nylas N1 is open-source and published on GitHub, meaning it will never be bought and axed.

Nylas N1 is the closest thing you’ll see to a next-generation mail program. It features a clean user interface, supports Gmail keyboard shortcuts, and best of all, because it is open-source, has a community to back it up. However, because it’s so new, you may run into some problems, at least in the short-run. For example, N1 doesn’t currently offer a unified inbox and the formatting isn’t quite right.

Why is N1 on our list? Because it’s been designed for easy modification. Best of all, it can run on multiple platforms including OS X, Windows, and Linux. Better still — it’s free. N1 is compatible with many providers, including Gmail, Yahoo, iCloud, Microsoft Exchange, and more. Currently, there is no N1 app for iOS.

You’ve Got Mail Options

If you’re happy with Apple’s default email client, keep it. For those looking for different ways to organize your mail or rather use something that plays nicer with Gmail, consider one of our alternatives. The most feature-rich solutions on the list are AirMail and Mail Pilot 2. The ones most likely to push mail into new areas in the next year are CloudMagic and Nylas N1. Looking for a reliable, stable solution? Consider Postmate.

  1. Hi! The article's great, although I think you should have put free email clients first.

    I would also like to suggest Hiri (www.hiri.com), an email client that helps you master the art of email. It's an innovation like no other client, and as a standalone app for Windows, OS X, and Linux, Hiri works perfectly!

    It's also free for personal use!

  2. Nylas N1 is not free anymore despite marketing shit they spread

  3. CloudMagic costs $19.99 to download. What do you people think 'free' means?

    The answer is not 'approximately twenty dollars,' despite what you may have heard.

  4. I really like Spark but for the love of god I wish they would go ahead and release a mac version already!!! Their iPhone and iPad version is good but I'm struggling to find an email client for the mac until further notice....

    • Jessica, I hope you may have found out that there is now a Mac version for Spark. It only supports IMAP though. I'm using Spark for iCloud since Apple Mail has become a complete hot mess on the computer (still works on iOS) and Apple Mail for my POP email accounts.

  5. Does Pegasus Mail work on a Mac?

  6. I might be wrong about this but CloudMagic keeps your user credentials in the cloud on their servers.

    Can anyone confirm this either way please?

    • Yes they do.

  7. Airmail is a disaster as of March 2016. Unstable and unfit for purpose.

    • Whats wrong with Airmail as of March 2016?

    • I agree. It seems to be more and more unstable. I had really high hopes for AirMail, but I'm out!

    • Airmail works perfectly fine. Still the best OSX email client. I wonder what issues you had with it.

      • The search is awful... and doesn´t have an undo send option.

  8. No MailMate mentioned? Really?

    • I second this, it is quite good...

  9. Thunderbird ain't bad but its getting old. Anyone know which other client supports multiple identities (besides Postbox that is)?

  10. For those using gmail with one of these native apps, what are you finding that missing compared to the gmail website client? I've tried various real clients over the years but gmails's search is awesome as is and haven't really found something lacking from the web client.

    • Have you tried http://mailplaneapp.com? Its a wrapper but pretty good if you're running OSX.

  11. Came to say the same thing as Peter, above. Cloudmagic is twenty dollars!

  12. What about Mozilla Thunderbird. It's also free and good.

    • +1

    • +1

  13. Airmail is absolutely the best OS X mail client out there. I am also beta testing Airmail's iOS app and that is going to beat the pants off everything else.

  14. Cloudmagic is nice, bit it's not free.

Email is, in many ways, the hub of modern life. Finding the best email app for your needs is key to a having a more manageable and productive digital experience, whether you're communicating with friends or restoring forgotten passwords. With Google's recent announcement that it will pull the plug on Inbox by Gmail in March 2019, and both Newton and Astro meeting their makers even sooner, you may be in the market for a replacement.

The best email apps help you manage the most important aspects of your digital life without making them more complicated. Some let you turn your inbox into a to-do list. Others are deeply customizable, giving you greater control. What makes the best email apps different from one another, and which one is right for you?

What Makes a Great Email App?

For this list of the best email apps, we only considered email clients, leaving out email services and email assistant apps. An email client is a piece of software you install on your computer or mobile device to access email, even if that email is hosted by another service. An example is the Mail app that comes pre-installed on iOS devices. By way of the Mail app, you can access a Gmail account and a Yahoo Mail account. Gmail and Yahoo Mail in this case would be email services, which we did not consider for this list of the best email apps. Client apps almost always let you access multiple email accounts, giving you the option to see all your messages in one consolidate view.

We also homed in on email apps for personal use, which nixed from consideration a few apps that tend to be more prominent in the business world, such as Microsoft Outlook (desktop app) and IBM Notes. They both have their place among email aficionados but tend to be more well suited for organizations than individuals.

As mentioned, we did not consider email assistant apps, or services that work within your existing email to make it better in some targeted way. An example is SaneBox, a service that works inside your existing email service to automatically sorts incoming messages (among other things). Another example is Boomerang, which adds new features and tools to Gmail and Outlook that help improve your writing and help you remember when to follow-up on messages. Both these apps are highly capable, but they aren't clients and so they weren't considered for this list.

There can be some confusion about email clients and services, however, because some apps cover both ground. Gmail, for instance, is not just an email service but also has a mobile email client app by the same name. The Gmail mobile app lets you read and reply to messages from not only your Gmail account, but also your Yahoo Mail address, Microsoft Office 365 account, and others.

In addition to being email clients, the apps in this list meet other criteria, such as being in a state of full release. In other words, no beta products allowed. (Don't worry. We have an eye on some of the more interesting email apps in the works, such as Pigeon and Superhuman. But we can't accurately assess them until they're fully released.) Ease of use played a major role in our decision-making, as did stability. We also looked for apps that had at least one standout feature or reason for choosing it, which is listed in the 'best for' line in each app's description below. Finally, if you're in search of an app with a specific feature in mind, see the comparison table at the end of this article.

When it comes to email apps, there's no reason you can't choose several to use for different purposes. You might have one app you adore installed on your personal computer, something else for work email, and yet another on your phone. Which ones you choose will depend on how you like to interact with your email and what you do with it. Whatever the case, the best email apps have you covered.

Best email app for merging email, calendar, contacts, tasks

If you're looking for a powerhouse of an email app for Windows, eM Client is a great option. It not only combines email, calendar, contacts, and tasks in one place, but also supports touch interfaces. While the price for a Pro account may sound a little steep, eM Client offers some functionality that's rarely found in other email apps, such as language translation. That's reason enough to choose eM Client if you frequently send and receive messages in multiple languages and aren't fluent in all of them.

Front

Best email app for team collaboration

Front app lets teams manage a single inbox collaboratively. With Front, you connect shared inboxes, such as catchall addresses like contact@company.com, and then anyone with access can answer or assign messages for other people on the team to answer. Front also lets you connect social media accounts, which teams may also tend to collaboratively.

Price: from $15/month per person, minimum 2 people

Gmail Mobile (Android, iOS)

Best email app for searching and organizing messages

While Gmail is the gold standard among webmail services, its mobile app is surprisingly light on features. But that's not the deciding factor on whether to choose the Gmail app for your phone. The real selling point of this app is how fast and capable it is at searching even the most bloated inboxes. When you use it with a Gmail account (or two; it supports multiple Gmail addresses), you get the same great options for automatically sorting mail into tabs that the service creates for you: Primary, Social, and Updates. With limitless ways to sort mail with filters and labels and exceptional spam filtering, Gmail makes it a breeze to see your most important messages quickly.

Price: free

Mail and Calendar by Microsoft (Windows; mobile equivalent is Outlook Mobile)

Best email app for keeping email simple

Mail and Calendar by Microsoft is a Windows desktop app that keeps email simple. Formerly called Outlook Express, this app covers the basics of email without adding excessive features. It offers threaded email conversations, notifications, and flags to mark your most important messages, along with Outlook-style calendar integration. It's also touch-enabled. If you're a Windows users who prefers to not be distracted by added features, it's a good option.

Mozilla Thunderbird

Price: free

Mail by Apple (iOS, macOS)

Best email app for annotating images, signing documents

The Mail app that comes preinstalled on iOS devices and most Macs may seem like a basic email client, but its simplicity belies the powerful tools under the hood. With its Markup tools, you can add annotations to images and sign documents right from your inbox. You can also use Apple's Mail Drop feature (the same one that works with iCloud) to send extremely large attachments without it eating into your allotted email storage space.

Price: included with Mac and iOS devices

Mailbird (Windows)

Best email app for increasing productivity with integrations

Mailbird is a Windows email app with a contemporary design. You can personalize your inbox with custom layouts and sidebar themes. It also includes integration options with popular productivity apps, such as Asana, Todoist, Slack, and others. While rich with features, such as the ability to snooze messages until later and automated scrolling for speed readers, some advanced capabilities are restricted to higher tiers of service. For example, an undo send option is only available to Mailbird Business subscribers.

MailMate (macOS)

Best email app for composing in markdown

Well suited for those who love plain text and keyboard shortcuts, MailMate lets you jump through your inbox without lifting your fingers from the keyboard. It also supports Markdown formatting and unique views, such as the ability to surface all messages that are similar to the message you're currently viewing. MailMate is perhaps the best Mac email app for power users who value plain text over features such as snooze and undo send.

Price: $49.99

Outlook Mobile (Android, iOS)

Best email app for viewing a focused inbox

While the Outlook desktop app is as powerful as it is bloated with features, the Outlook Mobile app offers quite a different experience. When you use it with a Microsoft email account, you can take advantage of its Focused Inbox view, which automatically finds emails that are likely to be important to you and filters out other distracting messages, keeping them in a tab called Other. The Outlook mobile app also has customizable swipe gestures for deleting, archiving, marking as read, flagging, moving, and snoozing messages (the snooze function is actually called 'schedule,' but it would be snooze in any other app).

Polymail (iOS, macOS, web)

Best email app for collaborating with a sales team

Polymail's strong suit is that you can use it collaboratively, especially among sales teams. Create email templates, for example, and you can share them with everyone on a team. For groups that use Salesforce, you can connect the two apps and get information you need from Salesforce while writing messages. Teams can also track email stats together to see how much time everyone spends in their inboxes, or how likely each person is to get a reply. Another great feature is Polymail's ability to watch and report back when recipients open your messages, and who among them downloads attachments you send. You'll also notice in the chart below that Polymail is packed with features, everything from the ability to snooze a message until later to an undo send button.

Price: free; paid plans from $13/month

Postbox (macOS, Windows)

Best email app for organizing multiple inboxes

Since its inception as a spin-off of Mozilla's Thunderbird, Postbox has grown into a powerful app, rich with options for keeping your mail organized. A tabbed interface lets you keep multiple messages open at once. Tags and folders help you categorize and sort mail. Another stellar capability is how Postbox can display a contact info sidebar, letting you dig into the detail about the sender. There's a lot to explore in this powerful and well designed app.

Price: $40

Spark (iOS, macOS)

Best email app for cutting down time spent in email

Every email doesn't need a lengthy reply. Sometimes a thumbs-up or crying face is all you need. With Spark, that's all you have to send, and in the end, that saves you time. After you read an email, tap Quick Reply to send an instant emoji response and archive the message in one step. Spark also saves you time in how it handles calendar invitations. Instead of a standard invite email, Spark shows you a preview of the event in your calendar with Accept and Reject options. This app has a wealth of other features, too, such as undo send, snooze, reminders, and more.

Price: free

Spike (Android, iOS)

Best email app for making email more like messaging

If you prefer text messaging or team chat to email, Spike (formerly Hop) is worth a try. This email client for Android and iOS devices turns message threads into chat-like conversations, so your emails look less like a verbose expanse of text and more like what you see in iMessage or WhatsApp, with GIFs, voice memos, one-tap image sharing, and everything else you'd expect in a chat app. And similar to team chat apps, Spike lets you create channels for organizing conversations around a certain topic. Spike works best when you use it to message with other people who are also using it, too.

Price: free

Thunderbird (Linux, macOS, Windows)

Best email app for working in tabs

From the makers of Firefox comes an email application that copies one of the best features of web browsers: tabs. Thunderbird isn't the only email client to use a tabbed interface, but it is one of the best. When you quit the app, Thunderbird saves your open tabs and reloads them the next time you launch it. An extensive collection of add-ons let you expand what Thunderbird can do.
