By Kristina Lauren · March 8, 2022

Many a tech blog headline and bold entrepreneur have announced that [insert app name here] will kill email. But like a wicked witch trying to kill a fairy tale princess, these new apps all fall short, and email continues to dominate.

You may be happy with a web app like Gmail when you're at your computer, but when you're emailing from your iPhone, you'll want a dedicated iPhone email app for the job. I spent several days testing the most popular iOS email apps, and here are my picks for the 10 best.

The 10 best email apps for iPhone

  • Mail by Apple for a no-frills email app

  • Outlook for a balance between simplicity and features

  • Gmail for integration with other Google apps

  • Triage for quick and easy inbox maintenance

  • Yahoo Mail for email management and quick finds

  • Unibox for humanizing your inbox

  • Chuck for extensive inbox maintenance

  • Edison Mail for frequent travelers and shoppers

  • Twobird for note-taking and scheduling from an email app

  • ProtonMail for privacy and security

What makes a great iPhone email app?

How we evaluate and test apps

All of our best apps roundups are written by humans who've spent much of their careers using, testing, and writing about software. We spend dozens of hours researching and testing apps, using each app as it's intended to be used and evaluating it against the criteria we set for the category. We're never paid for placement in our articles from any app or for links to any site—we value the trust readers put in us to offer authentic evaluations of the categories and apps we review. For more details on our process, read the full rundown of how we select apps to feature on the Zapier blog.

For starters, with one or two exceptions, I only considered apps that supported all the major email providers, like Gmail, Yahoo Mail, iCloud Mail, and IMAP accounts.

I also focused on standalone email apps for iPhone, rather than apps that are really just add-ons for a web or desktop app. I wanted to showcase email apps that could be the only way you accessed your email if you wanted. An Apple Watch companion app, however, was a bonus.

Since we're focusing on the iPhone, which you're likely using for personal use rather than intense work, I rejected any primarily team-focused or collaborative email apps, like Front. While these are useful for organizations, they're needlessly complicated for day-to-day emailing. They also tend to charge a monthly fee, and while there are paid apps on this list, we generally avoided apps that required expensive subscriptions.

Maintaining a clean inbox free of spam and clutter is top of mind for many, so I looked for apps that included some degree of spam filters, cleanup suggestions, and security options. Along those lines, I looked for apps that had the most efficient and creative methods of email organization.

On this list are also some great options for anyone looking for more productivity features in a personal email app, including note-taking, snooze options, and built-in calendars.

Even with all these criteria, there are a huge number of options to consider. So I dug in deep, put them to the test, and determined which ones were more than just marketing hype. As I went through each of the apps, my testing process involved:

  • Exploring all available features when composing and sending emails, like send delays, scheduling, and file attachments.

  • Assessing how well emails were received on other platforms.

  • Gauging how mobile-friendly and effective the app's UX design was.

  • Toying with customization options, like color themes and swipe actions.

  • Creating folders and changing filters to get a feel for organizational efficiency.

  • Tracking compatibility with major email service providers.

After days of testing, these are the best iPhone email apps.

Best no-frills iPhone email app

Mail by Apple

Apple's Mail app has had a bit of a bad reputation over the years—that's why there's such a healthy ecosystem of alternative apps—but that criticism is now largely unwarranted. Yes, it's one of the most basic apps on this list, but that's an advantage: it's a simple and easy-to-use email app. It handles your email—whether you use iCloud, AOL, Gmail, Outlook, Exchange, or any other POP or IMAP compatible service—without any fuss.

When you open the app, you'll see your email inbox with all your emails in reverse chronological order. To only see the unread emails, tap the handy filter icon in the bottom-left corner. It's nothing fancy, but it works great.

The only area where Mail steps beyond just sending and receiving emails is with a VIP Inbox and thread notifications. If you're overwhelmed by the number of emails you receive, it's tempting to turn off all notifications. Unfortunately, that means you might miss something important. Contacts added to the VIP list have their own dedicated inbox that always pushes notifications. Similarly, you can enable notifications for responses to individual email threads if, for example, you're waiting for a reply from customer support and want to know as soon as you get it.

If you don't need an app that does much more than send and receive emails, then Apple Mail is one of the best.

Mail by Apple compatibility: Gmail, iCloud, Yahoo, Hotmail, AOL, GMX, Exchange, IMAP accounts

Mail by Apple price: Free.

Best iPhone email app for a balance between simplicity and features


A screenshot of Outlook for iPhone, our pick for the best iPhone email app for a balance of simplicity and features

Microsoft's Outlook email app—surprising almost everyone—hits the best balance between usability and feature power. It supports all the major email services except POP3 accounts, so you don't have to use an Outlook or Hotmail account to make use of it.

The Outlook mobile app is a far cry from the desktop app. This isn't a bloated, enterprise product. It's a well-designed, highly functional personal email app that adds in some basic file management (with OneDrive, Google Drive, Dropbox, and Box) and a calendar, so you can handle all the extras around email, like attaching files and scheduling events, in one place.

Outlook automatically splits your inbox into a Focused Inbox, for what it considers important mail, and an Other Inbox for everything else. That, combined with powerful search and the Contacts section that groups together all the emails a specific person has sent you, make it easy for you to keep a handle on important messages.

The left and right swipe gestures are customizable: you can set them up to archive, delete, reply, move, or schedule (Outlook's take on snooze) emails. And there's even an Apple Watch app so you can check your email on the go.

Outlook Compatibility: Outlook, Yahoo, Gmail, Exchange, iCloud, Hotmail, Live, MSN, Accenture, Infosys, Cognizant

Outlook price: Free

Best iPhone email app for integration with other Google apps

The Gmail iOS app brings the familiar Gmail web app experience to your iPhone. Whether this is a good thing or a bad thing depends on how you feel about Gmail.

While Gmail for iOS does support iCloud, Outlook, Yahoo, and IMAP, it's at its best when used with your Gmail account. The iOS app nicely integrates with Google's other services like Google Drive, Google Docs, and Google Sheets. For example, you can preview any file shared through Google Drive or one of Google's apps. A single tap then either saves it to your own Google Drive, which you can access through the Attach option when you're writing a new email, or opens it in the Google Docs or Sheets app, so you can edit or update it. You can also respond to Google Calendar invites straight from the email, just by tapping on the Yes, No, or Maybe. The integrations extend to video chat: instead of needing to download the Meet app separately, you can handle all your video conferencing in-app. And with Zapier's Gmail integrations, you can connect Gmail with thousands of other apps too.

Outside of these integrations, Gmail is still a competent email app. In terms of customization, you can choose the default view, which shows an icon for each sender and a preview of any attachments; or you can select Comfortable (which removes the previews) or Compact (which removes the icons as well, letting you see more emails at once). All your emails are sorted into three separate inboxes: Primary, Social, and Promotions. Search is, as you'd expect from Google, lightning fast. Emails can be snoozed, and if you accidentally send an email too soon—which is easy to do on a phone—you can tap Undo to rescind it.

Gmail compatibility: Gmail, iCloud, Yahoo, Hotmail, Outlook, Live, Office365, IMAP

Gmail price: Free

Best iPhone email app for quick and easy inbox maintenance


A screenshot of Triage, our pick for the best iPhone email app for quick and easy inbox maintenance

Triage may be the most simplistic email app on this list, but I'd say it's by far the most innovative.

This Apple-only app is touted by its developers as "first aid for your inbox." The format is simple: your emails are presented as "cards" that are stacked on top of each other. You can swipe left on an email to archive it, swipe right to keep it, and tap on the card to expand and reply to it. And that's basically it. It's like Tinder for emails, except (hopefully) a lot more effective.

Of course, Triage isn't necessarily meant to be used by itself. Think of it as a useful complement to your typical, more extensive email software. The main goal of this app is to make inbox maintenance a little more manageable, especially if you're like me and are prone to accumulating loads of emails. 

Triage ends up having somewhat of a game-ish feel to it. If I found myself bored in a waiting room, I could easily pass the time by hopping on the app and swiping away at my pile of emails.

Triage compatibility: Gmail, iCloud, IMAP

Triage price: Free; $9.99/year for a more advanced plan which includes multiple inboxes

Best iPhone email app for email management and quick finds

Yahoo Mail

The Yahoo iPhone app, our pick for the best email app for email management and quick finds

While Yahoo may not be the web behemoth that Google now is, the Yahoo email app is still a force to be reckoned with. The iOS app is packed with loads of features that are perfect for those who want better organization and don't mind a little in-app entertainment. The app is compatible with non-Yahoo email services as well.

You can tap the Subscriptions at the bottom of the screen to manage all your mailing lists. This page is split by Active subscriptions, Unsubscribed, and Discover, the last of which recommends popular newsletters. The Unsubscribed tab shows you your list of inactive subscriptions, with a one-tap option to block the sender. This can come in handy if any shady newsletters decide to ignore your request.

Yahoo Mail additionally highlights deals and discounts in your emails through their Deals view, allowing you to see when offers from your favorite companies will expire and making it easy for you to find discounts without having to comb through your emails. You can also view all your emailed receipts in one view; and any travel details, such as reservations, flight tickets, and travel offers, in another.

Sending emails is convenient, with the ability to easily attach files from Dropbox, Google Drive, or your device (many email apps don't readily present Dropbox and Google Drive as options, so this is a nice, simple gesture). Through their existing collection, you can also send GIFs or use colorful, artsy backgrounds (called stationeries) in your emails.

Yahoo Mail doesn't stop with just email—with a window dedicated to weather reports and a feed with the latest news, you'll have plenty of entertainment when you're not focused on your inboxes.

Like any app, Yahoo Mail does have its downsides—the in-app ads can be a bit distracting for those who are interested in just looking at emails, but they aren't very invasive, and you can get rid of them by paying $1.99/month for the Yahoo Mail Plus plan. Yahoo Mail's iPhone app also doesn't offer a unified inbox. Instead, you have to tap the icon in the upper left to navigate between your inboxes. But switching took me less than a second to do, which makes this just a minor annoyance—and the benefits of Yahoo Mail far outweigh any of these issues.  

Yahoo Mail compatibility: Yahoo, Gmail, AOL, Outlook, Office 365

Yahoo Mail Price: Free; $1.99/month for Yahoo Mail Plus, which includes ad-free email, reply reminders, and domain blocking.

Best iPhone email app for humanizing your inbox


A screenshot of Unibox, our pick for the best iPhone app for humanizing your inbox

Unibox throws out the standard email inbox conventions. When you open the app, you'll see all emails automatically grouped by sender, and then arranged by date. As soon as you tap on a name, you'll see the most recent message and all your previous conversations with that person; you can even see all the files and photos they've sent you by tapping on the paperclip in the bottom right corner. If you think of email in terms of who you're communicating with, it's perfect.

Aside from this novel take on email sorting, Unibox is relatively feature-light. You can customize what the swipe gestures do in the settings menu, but there's no snoozing, scheduling emails, or any of the features common in advanced email apps. You can't even use multiple accounts or custom signatures without paying for Unibox Pro ($4.99), and it doesn't support POP accounts.

Unibox compatibility: Gmail, Outlook, Live, Hotmail, Yahoo, Office365, Exchange, IMAP, self-hosted servers

Unibox price: Free; $4.99 for Unibox Pro

Best iPhone email app for extensive inbox maintenance


The Chuck iPhone app, our pick for the best iPhone email app for extensive inbox maintenance

What's unique about Chuck is the variety of ways in which you can view your inboxes: by month, subject, or sender, all of which I found super helpful in locating specific emails faster.

Unsubscribing from multiple email lists is also quick and smooth: when you tap on the bottom-right, you're guided to a page with all your mailing lists, where you can select specific subscriptions and unsubscribe from them all at once.

The free plan of Chuck should be sufficient for most, but if you want to step up your filters and organizational features, you can upgrade to become a Pro user. I made use of the seven-day free trial to explore this more extensive plan, and I was able to add as many inboxes as I wanted, block senders, and try out Chuck's cleanup suggestions. If you know you need to tidy up your inbox, but you're not quite sure where to start, Chuck will recommend categories of emails to get rid of, including old messages, social media notifications, or even messages that weren't addressed to you.

Another small plus: when composing emails, you can easily add links to text, a feature I've been craving for ages now since the vast majority of email apps don't allow it without some smart workaround

Overall, it's a very efficient app with great filtering capabilities, one-tap tasks, and cleanup suggestions.

Compatibility: Gmail, Outlook, Yahoo, iCloud, AOL, Office 365, IMAP

Chuck Price: Free; Chuck PRO plan for $3.99/month or $39.99/year.

Best iPhone email app for frequent travelers and shoppers

Edison Mail

Edison Mail takes intelligent email sorting to the next level: subscriptions, purchase receipts, and even travel details and package shipping details are automatically identified and sorted into the correct groups, which you access from the sidebar.

You can then quickly glance at your favorite newsletters, unsubscribe from ones you no longer read with a single tap on the unsubscribe button, see upcoming trip details like boarding gates and departure times, and track your parcels, all without having to dig deep into your email archive. Edison will even use the information to send you smart notifications, letting you know when your flight's gate has changed or your package is out for delivery.

In addition to the assistant, Edison is a full-on modern email client: it supports all the major email services and offers undo send, customizable swipe gestures, snooze, and smart replies for when a short response is all that's needed. And my new favorite way to mark an email as read? Just swipe the little blue unread dot, and it vanishes.

Edison compatibility: Gmail, IMAP, iCloud, Yahoo Mail, Outlook, Comcast, AOL, AT&T, and more

Edison price: Free

Best iPhone email app for note-taking and scheduling


A screenshot of Twobird, our pick for the best iPhone email app with note-taking and and scheduling

Twobird allows you to kill two birds with one stone (cute!): the app functions as your typical email app, but it also has decent note-taking capabilities. When you tap the green button at the bottom of screen, you'll be taken to a page that's almost reminiscent of iOS's Notes app and functions similarly. You can start typing to take notes, but you also have the option to create checklists, add comments to existing notes, and assign contacts to notes. Then, once you're done, you can share your notes through email or by copying a link to the note, which can be made public.

You could even argue that Twobird has a third bird hidden in there, with its scheduling capabilities. Sharing and making plans with your contacts is straightforward when you use Twobird's built-in calendar. This feature seems to borrow from Google Calendar, allowing you to schedule events or meetings with any of your contacts, with the option of adding Google Meet video conferencing.

The biggest drawback of Twobird is that it only works with Gmail and Microsoft accounts, a flaw that Twobird will hopefully fix in the future. (If you need an app with similar productivity features and more email service options, give Airmail a try.) Another minor issue for me is how long the app took to load my emails after initially adding an inbox—most of the other apps on this list downloaded emails immediately, but Twobird took a few minutes or more. Again, it's minor and may not be the case for everyone, but it's something to be aware of, so you don't rush to delete the app before you can enjoy all it has to offer.

Twobird compatibility: Gmail, Outlook

Twobird price: Free

Best iPhone email app for privacy and security


A screenshot of ProtonMail, our pick for the best iPhone email app for security and privacy

If you're not familiar with using more secure email services, ProtonMail makes the process easy. You can compose an email as you normally would, but if you click the lock button, you'll be asked to set a password to encrypt your email message. Then, once your recipient gets your email, they can click to view your message; they'll be directed to a browser to input a password. You can use this process to send emails securely to non-ProtonMail users, but emails are automatically encrypted if you're sending to contacts who also have ProtonMail.

The only thing that could be a bit of a hassle is that, if you want to access your inboxes from other email service providers (Gmail, Yahoo, and Outlook/Hotmail) through ProtonMail, you'll need to set up mail forwarding. But this just comes with the territory of using an email app that's specifically designed for privacy and security—even the free plan of ProtonMail doesn't allow ads, which means that your emails aren't being scanned to deliver personalized ads as would be the case with other email services.

Another great alternative to ProtonMail is Tutanota—it has similar security features with end-to-end encryption and even more to offer when it comes to inbox maintenance and spam controls; its biggest weaknesses are the lack of mail forwarding and the inability to reset your password without a recovery key.

ProtonMail compatibility: You can set up mail forwarding through Gmail, Yahoo Mail, and Outlook/Hotmail

ProtonMail price: Free; ProtonMail Plus is $59.99/year, includes 5 email addresses, 5 GB of storage, and IMAP/SMTP Support

The iOS email app universe is saturated with options—some excellent, some...not. But with all the choices, one is bound to fit how you use—or aspire to use—email. If you're not sure which one's right for you, try more than one. They're all free or cheap, and it can be fun to experiment with a few different styles for managing email on your phone.
