Best Email Apps for iPhone

One of the most frequently used applications on any iPhone is email. Whether you rely on email for business or personal, it’s a vital application and one that you will likely interact with countless times throughout a typical day. With iOS 7, Apple’s stock mail app underwent some major interface changes, but functionality has largely remained the same. That’s continued with iOS 8. Sure we swipe left, instead of right to delete mail, but there has been little in the way of innovative changes to make users more productive. While Apple’s stock mail app has remained somewhat stagnant from a features standpoint, there are a number of developers that are rethinking how we should manage our inbox. So while the default Mail app ‘just works‘, these apps are pushing the envelope. So whether you’re frustrated with Apple’s┬ámail app or looking for new ways to wrangle your inbox, we’ve compiled a list of the best email apps for iPhone in 2015.

Microsoft Outlook

Editor’s note: The following apps were tested using Gmail and iCloud. While some of the apps included do support Exchange, IMAP accounts, they were not tested during these reviews.

Microsoft Outlook

This might come as a surprise, but Microsoft has designed a spectacular email client, that might very well be the best of the bunch. This didn’t happen by accident, but instead by acquisition. Last year, they acquired Acompli, a company who by themselves had create a nifty email client for iOS and Android. Bringing much of what was loved in Acompli to Outlook has been surprising. So why the excitement over Microsoft Outlook? It provides a ton of features and tools that can make the time spent pouring over your inbox so much more productive.

It supports all the major email providers (iCloud, Gmail,Yahoo, Microsoft Exchange) and setup is a snap. In a matter of seconds, you’ll find yourself looking at your unified inbox. If you prefer, you can also look at them separately. Microsoft divides your email based on what their algorithms feel are the most important. These are categorized as your ‘Focused Inbox’. You can move emails in and out of this inbox, creating rules along the way to improve the resulting inbox. This feature can be disabled, but could prove useful if you find yourself overwhelmed with email.

Focused inbox

Where most email clients stop and end with email, Microsoft integrates a full calendar. You can share times and schedules without switching apps. Adding an appointment within your email application is glorious. It’s amazing that something so simple can have a bit of a eureka-effect.

Outlook Calendar

Swiping to manage your inbox is certainly a big trend in 2015 and it’s excecuted flawlessly in Outlook for iOS. The settings panel lets you change preferences. You can also set your default calendar and your preferred browser. At some point, maybe iOS 9, we’ll get the opportunity to select default apps which override Apple’s stock app. Having this option in your email client is a bonus, since it’s a frequently used app.

A unified search feature returns emails and people from your contacts. If you select a person (or select them from the People tab), you’ll see a grouping of emails to and from them, any meetings and files. It all just makes incredible sense.

As for those files, one might expect they would be limited to Microsoft’s own OneDrive. While it’s a pretty good cloud option (with 10GB free for sign-up), you can also choose to use files from Dropbox, Box and Google Drive. You can use all of them, if you’d like. The files tab provides easy access to those files, which attached to new emails, shared via Messages, AirDrop or countless other options.

When you add of this up, you get an incredibly feature-rich email client that works with all major services, most major cloud services and integrates them all incredibly well. If Microsoft was able to push this out just two months after its aquisition, the future is bright for Outlook for iOS.


Mailbox created quite a buzz when Orchestra launched the app to long virtual lines that required folks wait to gain access. The delays associated with the reservation system are long gone, but Mailbox remains a strong email app. Orchestra has since been acquired by Dropbox, providing an added benefit of experience scaling services, a requirement for an app that has gained a great deal of popularity amongst iOS users.

Mailbox inbox

You’ll need a Gmail or Google Apps account in order to use Mailbox, however the company is working on adding support for new services. Mailbox was created for mobile and the iPhone in particular. Mailbox can check your email from the cloud, resulting in fast transmission of new messages and notifications. Mailbox was noticeably faster delivering new mail than any of the apps tested.

Inbox zero. The goal we all strive to meet and Mailbox provides the necessary tools to make that a reality. When a message arrives in your inbox, the stock mail app allows you to Archive, effectively storing it away in folder in Gmail. If you swipe right in Mailbox, the very same action occurs. If you increase the length of your swipe, for example edge to edge, it will delete your message.

Mailbox excels by providing so many more options. While Mail puts off decision making for another day, Mailbox allows for a series of actions. A partial swipe will reveal a yellow bar that on release pops up into options for when you want to revisit an email. Mailbox creates a series of folders which it will use to store you messages. This helps to keep your inbox manageable and will return the message based on your preference. Either select from the provided options, pick a date or select the vague ‘Someday’. At any point, you can select the clock tab at the top to view your messages.

Actions time

Using the same swiping motion, but going further in the swipe, brings up a ‘To-Do’ action. Mailbox has presets for To Buy, To Read, To Watch or you can create your own.

Tapping on the menu icon provides for a simple categorization of your inbox management. The app moves fast and uses color to help with visual recognition of an inbox category.

All this is done using a minimalistic user interface that’s a pleasure to use. It gets out of the way, so you can focus on managing your inbox. Font size is slightly smaller than the stock app, which could be troublesome for some. It does provide you with an expanded view, so you can see more email previews. Despite Gmail being the only option, Mailbox does not support labels, which might be a deal breaker for some.

Tip: If you scroll to the bottom of your inbox, Mailbox provides you with an option to ‘batch swipe’. Sure it’s cheating, but it’s a quick way to declutter your inbox allowing for quick archival of your messages.

Batch archive

Mailbox is a fast and intuitive app that will have you swiping your way to inbox zero in no time.

Mailbox (free) is available for download in the App Store.


Boxer offers support for Gmail, Outlook, Exchange, Yahoo, iCloud, AOL and IMAP. If you have multiple accounts, you can view them separately or use the unified inbox. Like Mailbox, Boxer makes heavy use of a variety of swipes to create actions. A swipe left will archive a message. Go further and it deletes. Swipe right reveals an ‘Action’ menu, a group of boxes that allows for insane levels of inbox management.


As someone who is consistently doing battle with an ever growing inbox, I’ve started to rely heavily on labels in Google. Among the actions are labels, which will bring up a list for easy categorization. Selecting a label, moves it out of the inbox and neatly organized, something not fathomable in the mail app.

Boxer is also part task manager. Select ‘To-Do’ and you can set due dates, add priority and add an assignee.

Boxer task

A unique feature of Boxer is the ‘like’ option. It generates an email back to the sender/recipients with a short message that you like it. On the topic of short messages, Boxer includes an incredibly useful Quick reply feature, also part of the action set. There is a rather generous selection of quick replies you can utilize or create your new ones using the templates in settings. For those looking for even more robust tools, Boxer provides support for the SaneBox, a paid service that providers for smart filtering, attachment organization and a one-click unsubscribe among other features.

I mentioned earlier how Boxer provides either individual or unified inboxes. A ‘dashboard’ view provides a quick overview of your inboxes, to do list and emails that have been assigned. This is a high-level look at your inbox.

The settings section of the app provides a wealth of customization options. You can customize most every aspect of how this app interacts with your swipes, initial launch screens and more. Boxer excels on so many levels at providing a robust email management solution.

Boxer ($0.99) is available for download in the App Store.


Triage offers support for Gmail, Yahoo!, iCloud, Outlook and IMAP. While most apps provide you with email in list format, this email app takes an entirely differect tact. It stacks your inbox, forcing you to make a decision on emails, either swiping up to archive or down to keep. This app feels less like a comprehensive email management solution, but for some, that’s exactly the appeal. The simplicity, forcing an A/B choice due to the lack of list of emails, requires action to move to the next message. It felt like playing Tetris with my inbox, with each swipe moving closer to a goal of inbox zero.

Triage email for iPhone

The app supports multiple inboxes, but does not provide a unified inbox, although switching between accounts is easy enough. Personally, I’m too tied to the conventional email inbox, that I could not see this as my primary go-to email. Despite my personal preference, this app certainly executes well upon its goal of allowing users to use their downtime to ‘quickly remove the noise and stress.’

Triage is a unique, simple approach to email management that can make cleaning your inbox fun, easy and stress-free.

Triage ($1.99) is available for download in the App Store.


What feels like a nice remix of of the stock app (provided you like the color red), myMail feels at home in iOS 7 and brings with it a few new tricks you won’t find in the stock app. It supports all of the major email services. A unified inbox is not on the list of features, but there’s plenty to like about this email solution that goes beyond it’s gorgeous user interface.

Your inbox can be customized to your preference. Unlike some apps we’ve reviewed, myMail allows you to turn the sender avatar on or off. I receive a lot of email from people I don’t know, which can result in ‘generic’ avatars that can be visually overwhelming. I appreciated the level of customization.

No avatars

There is a one-way swipe action in myMail that brings up a series of options. You can favorite email, an option that’s supported in both iCloud and Gmail. The thumbs down provides for a quick ‘spam’ action that will send all messages from a particular sender to the trash. A ‘move’ feature is akin to labeling in Gmail and you can quickly scroll through labels and sort your mail.

Labels support

One drawback to some of the newer email clients that use swipe actions is the inability to select multiple emails. This app provides both which is a boon to those who enjoy batch processing.

For plenty of folks, the stock email app works perfectly fine and they have no reason to switch. If you find yourself inundated with email or looking for an alternative to the stock mail app, there are a wealth of great alternative email apps for iOS in 2015. The action based systems some of the above employ help users file and organize email. That alone should help you reach the coveted goal of inbox zero, a task you’d find more difficult using the default mail app.

Since the first iPhone, I’ve used the stock app for email. It’s been solid, but not spectacular. Having surveyed the field of available third party email apps, I’m once again reminded of how the iOS ecosystem is rich with alternative options for most any app category. If you are looking for a fresh take on your inbox, this list of the best email apps for iPhone is a great place to start. What’s your favorite?

    The only problem is that Outlook for iOS does NOT import all of your contacts! It only uses recent ones…. Why is it hobbled this way?

  2. Dan says

    I’ve read a few reviews of Triage along the lines of “well I don’t think I could use this as my primary email client” but all these reviews are completely missing the point of this app. It is, as its name suggests, ONLY for triaging your inbox. Nothing else. The idea is you use this first, and then use your primary email app.

    Thank you , Thank you , Thank you !!
    I have used several mail apps on my iPhone & the Outlook one is absolutely awesome and way way superior (IMO)


  4. Larry McJunkin says

    I understand your jubilance regarding Outlook for iOS…it’s a great app. But you might not have noticed a glaring problem I doubt they’ll ever fix.

    If you add a Gmail account Outlook uses the Mail, Calendar and Contacts from that account. Then add an iCloud account and of course it uses the Mail, Calendar and Contacts from that account as well.

    The problem is that Outlook allows you to choose your default calendar from either account as well as default Mail. But, it simply uses the Contacts from both accounts…producing duplicate contacts in Outlook “People”. Adding a third account does the very same thing.

  5. Chris Webster says

    Agree there is a problem with duplicate contacts with Outlook. Has anyone compared Outlook directly to Boxer?
