Best Third Party Mail Client For Mac

The best free email clients for managing all your email inboxes, calendars and instant messages. Thunderbird is an unusual email client that's expandable via a huge selection of third-party. Postbox is stand-alone email client for Windows and Mac operating systems. Postbox is based on Mozilla-code, so the Postbox team has been able to tweak quite a few Thunderbird extensions.

A free email client can change your life. That might sound ridiculous, but consider how long you spend each week checking your inbox, replying, forwarding and composing. It could easily be several hours, and even more if you use several different email addresses (as many of us do).

Using a dedicated email client not only makes it easier to deal with multiple email accounts, it also means you can take full advantage of extra features such as a calendar, contact management, and neat integration with other desktop software you're using. As with so many other types of software, email clients are not born equal, and it's important that you don't lumber yourself with one that is underpowered, confusing to use, or that offers poor performance.

Take a browse through our best free email client selection and you will undoubtedly see a few familiar names. But you'll also find some that you may not have heard of or tried, so perhaps it's time for you to test drive a new email client!

Best Mail Client For Mac

1. eM Client

The best email client, with support for a huge range of email providers, integrated chat, smart translation, and simple migration

Integrated chat
Only supports two email accounts

eM Client has been around for nearly 10 years now, and throughout that long development it's evolved into the best free email client for Windows.

eM Client makes it easy to migrate your messages from Gmail, Exchange, iCloud and Outlook.com – just enter your email address and the client will adjust the appropriate settings for you. eM Client can also import your contacts and calendar, and it's easy to deselect these options if you'd prefer to manage them separately.

There's an integrated chat app too, with support for common platforms including Jabber and Google Chat, and the search function is far superior to those you'll find in webmail interfaces.

Unlike most free email clients, eM Client is also packed with advanced options like automatic translation, delayed send and encryption. It's a remarkable set of tools, and for managing two email accounts, it's ideal.

If you have more accounts, it's well worth considering upgrading to eM Client Pro for a one-off fee. This lets you connect an unlimited number of accounts, access VIP support (in the unlikely event that you need it), and use the email client commercially.

2. Mailbird Lite

A great-looking client packed that connects all your social apps

Very easy setup

Mailbird Lite isn't just an email app – it's a whole communication platform to which you can add apps for scheduling, chatting, file syncing and teamworking.

Free users miss out on features such as speed reading, email snoozing and quick previews of attachments, but Mailbird Lite is still an excellent choice. The Lite version only lets you connect one email account but, it's optimized for speed, and looks great to boot.

Setup is simple; enter your email details and Mailbird Lite will find the necessary POP or IMAP settings automatically, then get to work importing your messages. It offers to connect with your Facebook account, so it can liven up your inbox with your contacts' profile photos, and can also link with Whatsapp, Google Calendar, free task manager Moo.do, and teamworking app Asana.

3. Hiri

Packed with time-saving tools that'll improve email habits

Smart productivity tools

Hiri is usually a paid-for premium email client, but it's free for TechRadar readers. It's designed primarily with business users in mind (it currently only supports Microsoft email services including Hotmail, Outlook and Exchange), but home users will also appreciate its productivity-boosting features.

If you find yourself spending too long managing, reading and replying to emails, Hiri is the email client for you. It includes a smart dashboard that lets you see how many unread messages you have at a glance and how long you should wait before checking them (after all, how many really need an instant reply?)

The Compose window is designed to save you time too, offering only the essential options (no fancy formatting) and including the subject line at the bottom so you don't have to write it until you know how to summarise the message.

These little touches make Hiri a truly exceptional client. If Microsoft is your email provider of choice, it should be well up your list.

4. Mozilla Thunderbird

Plenty of features and extensions – as you'd expect from Mozilla

Expandable via plugins

Thunderbird, from Firefox developer Mozilla, has just undergone a total overhaul that brings it right up to date. Not only does it look smarter, it also works much better. You no longer need to download and configure an extension to make full use of your calendar, and cutting, copying and deleting events is effortless.

You can connect as many email addresses as you like to Thunderbird, and it's totally free, with no ads or prompts to upgrade. It's also very flexible, with a wealth of customizable options – and if you can't see a particular feature, you can expand Thunderbird with third-party extensions.

Thunderbird still takes a little getting used to (there are so many options, the interface is a little confusing at first), but it's a superb email client that'll serve you well – particularly if you have lots of accounts to manage.

5. Spike

Give your inbox the WhatsApp treatment

Helpful chat-style interface

Mail Client For Mac Os X

Spike is a versatile free email client, available for iOS, Android, Windows and Mac, with a handy web app for those occasions when you don't have time to spend installing software.

It's billed as the first 'conversational' email app, which essentially means it presents messages and replies in bubbles in real time, in a style that looks very much like WhatsApp. This works particularly well for the type of short emails that you're likely to send to friends and family, making it refreshingly simple to keep track of long email chains that would usually be a mess of nested messages.

Spike is free for personal use, with support for an unlimited number of email accounts and up to 10 'group chat rooms'. If you're sick of trawling through messy lists of replies, it's a breath of fresh air.

  • What's the best web browser you can download today?
  • These are the best email clients (paid for)

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.

Best third party email client

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.

Best Third Party Email App For Mac

  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.
