Best email clients for Linux, macOS and Windows Webmail interfaces allow users to access their mail with any standard web browser, from any computer, rather than relying on an e-mail client. However, e-mail client remains extremely popular in a large corporate environment, small business, home and power users.

The Mac’s default Mail application (also referred to as “Mail.app” or “Apple Mail”) has a somewhat checkered past.

While Mail.app provides a free, full-featured email client on every Mac and has even pioneered some innovative features over the years (like VIP and Handoff), it’s definitely not for everyone. It can be buggy, occasionally has issues playing nice with Gmail, and lacks some more advanced features that are present (and have been present for years) in other third-party email clients.

If you use plug-ins to extend Mail.app’s functionality, Apple has a history of making changes that cause developers to re-write their plugins, resulting in a broken email workflow while you wait for updates.

Fortunately, there is no shortage of excellent third-party email clients that aim to fix Mail.app’s shortcomings. In this article, we’ll take a look at several of the more popular options and introduce you to our favorite.

Criteria for the Best Email App

In selecting the best email app for macOS, we used the following criteria to select the winner:

Overall Design — Dealing with email can be annoying, and using a poorly-designed email client can compound the frustration factor. The email client you decide to use should provide you with a well-designed user interface that aids you in your quest for Inbox Zero.
Ease of use — The email client you use should give you the tools you need to get the job done while staying out of the way as much as possible. You want to focus on reading and responding to email, not navigating complex menus or trying to figure out basic functions.
Innovative Features — As the amount of email we receive grows over time, the way we deal with it must evolve. Developers are starting to reconsider how we fundamentally deal with the email we receive, and it is important that we consider innovative features that make it easier (and more enjoyable).
Support for Multiple Account Types — The best third-party email clients are flexible enough to offer support for many different types of accounts, such as Gmail, iCloud, O365, Yahoo, Exchange, IMAP, etc. If an email client doesn’t support your email provider, then it’s just not an option for you — no matter how awesome it looks.
Support for Gmail-Style Shortcuts — If you’ve ever used Gmail keyboard shortcuts, you probably can’t imagine not using them since they can drastically reduce the amount of time you spend in your email client. For example, to archive a message in Gmail, you just have to press the “e” key, compared to using “Shift + Command + A” in Mail.app (you can view a complete list of Gmail keyboard shortcuts by pressing “?” in Gmail). These shortcuts can be a game-changer for how you read and respond to email, so it’s important that the best third-party email client for Mac support these.
Update Schedule — The email client you use should have a track record of being well-supported to minimize the risk of it suddenly disappearing, forcing you to figure out a new tool for your email workflow.
Integration with Other Apps/Services — Email doesn’t happen in a vacuum. Many emails you receive have a task associated with them or a file you need to save for later, so it makes sense that you should be able to link that email message to your task management system (like Things 3, our favorite GTD app) or a cloud storage solution like iCloud, Dropbox, or Google Drive.
Customization/Widgets — A good email client is flexible enough to support customization. Email is personal, and some email clients allow you to install widgets or plugins that can extend the core functionality, enabling you to create a very custom application that meets your specific email needs on any device.
Plays Nice with IMAP Folders — Some apps (rather sneakily) create additional IMAP folders for extended functionality, which (at best) creates additional clutter when you access your email outside of that email client, and (at worst) can cause major problems in your email-based workflow (i.e., when you can’t find a message because it’s actually sitting in a “hidden” folder).

Our Favorite Email App: Spark

Spark is our favorite third-party email client for the Mac because it has a great combination of powerful features and a clean, well-designed user interface. It’s a great productivity tool for individual users, and also offers some innovative features for teams that need to collaborate on emails together.

Everywhere you look in Spark, there are features focused on making email better. The first thing you’ll notice is the Smart Inbox, which collects emails from all of your accounts and automatically organizes them into categories like Notifications, Newsletters, Personal, and Seen. This shows you the real emails from real people first so you can respond to the things that are important and save the rest for later.

Another unique feature in Spark is Quick Replies, which allows you to send short, templated responses. These are handy when you need to indicate that you’ve received or seen an email but don’t necessarily need to type out a lengthy reply. And if the message doesn’t require a response, you can use 4 different swipe gestures to mark it as read, archive it, pin it for later, or delete it entirely.

One of the things that Apple Mail gets right is the support for smart mailboxes. These allow you to create custom mailbox folders that automatically organize your email messages based on criteria like who it’s from, what’s in the subject line, or what day it was received. Once you set up and use smart folders in Apple Mail, it can be hard to switch to an email client that doesn’t support it. Fortunately, Spark has support for smart mailboxes but they are even easier to create thanks to the built-in smart search feature. Smart search appears all over the place in Spark, and functions a lot like Spotlight for your email client. All you have to do is start typing and Spark instantly shows you the available options.

Spark also has a built-in calendar view, which can be useful when replying to a message requesting a call or meeting at a specific time. But what makes this feature really useful is the way it’s implemented. There are other email apps that build in calendaring functionality, but it’s either self-contained or uses a weird syncing protocol (I’m looking at you, Outlook). Spark does it a little bit differently. If you use something like Google or iCloud and then create calendar events in Spark, they will instantly show up on all your calendars in all your apps (like Fantastical or BusyCal). The difference is subtle, but important — Spark is not trying to be your calendar, it’s just allowing you to access your calendar. There are some obvious limitations with this based on your account and service type. Such as, if you set up a standard IMAP account in Spark, the calendar view isn’t going to help you, but it is nice for the account types that support it.

In addition to Google and iCloud, Spark supports quite a few different email account types, including:

Yahoo
GoDaddy
Aol Mail
Hotmail
Outlook
Office 365
Microsoft Exchange
GMX
Zoho
Fastmail

Spark also integrates directly with other productivity apps like Things, OmniFocus, and Bear, just to name a few. While the integrations provide much of the stan
