The 11 Best Email Apps for iPhone in 2024

Years ago, in 2007, Apple announced the release of the first iPhone. Over time, each model has become more innovative, but its default email app still needs to catch up with the iOS updates. Despite the prominence of team chat apps, email remains a crucial tool for business communication. This has led to the development of new, feature-rich email apps that offer better functionality with group messaging, collaboration, and video chat integrations.

We’ve researched and listed the best email apps for iPhone and iOS, compatible with iOS 15 and beyond. With the apps we’ve included, you’ll upgrade from Apple’s outdated email app by choosing one of these modern options and setting it as your default. Simply go to the Mail settings on your iPhone and select from the list of email providers or manually add the account of your choice.

2. Apple Mail

Considered by some to be the best email application for iPhone, Apple Mail first hit the scene in 2004 and is a favorite of busy (lazy?) Mac users by default. Of course, it’s still got plenty going for it as a standalone email app, and its integration with the macOS suite of tools makes Mail a great all-rounder.

Full support for Apple’s iCloud storage brings this elder statesman into the modern era and you can easily send files of up to 5 GB. Another plus point is the simple search feature that lets users navigate multiple POP, IMAP, Exchange, and iCloud accounts all together in the same place, helping you to find specific emails even if your inbox is overflowing.

3. Outlook

Having been around since 1997, MS Outlook is a tried and tested favorite—particularly among business users. The Outlook email app for iPhone is reliable and relatively easy to use, and it remains a popular choice for many people. Perhaps unsurprisingly, the iOS version is relatively new, as until recently, Microsoft didn’t support their major rival’s platform. Unfortunately, this also means that not all Outlook functionality is supported.

Ideal for anyone using Microsoft 365 on a regular basis, Outlook ensures near-seamless integration with the company’s wider suite of tools on the iOS platform. This includes MS Excel and Word, as well as a useful calendar. Unfortunately, it doesn’t integrate so will Apple’s iCloud, meaning you might have some cross-compatibility issues.

4. Gmail

No iOS email app list would be complete with a nod to Google, and for many people Gmail is the epitome of free email. In fact, users of any of the iPhone email apps almost certainly have at least one Gmail address, so using the iOS email app is completely logical.

The app itself supports all the major email accounts, allowing you to consolidate all your email addresses in one place. However, when managing multiple inboxes with the app, it’s not the most intuitive experience when compared to other Apple email apps. A useful Undo Send feature, alongside comprehensive integration with the Google calendar with excellent notifications and reminders do make up for it though.   

If you aren’t in the Gmail ecosystem or want to avoid using an app that tracks you for advertising purposes, you’ll want to avoid the Gmail app. Gmail is a very secure service, but Google makes all of its money from advertising.

5. Newton

Newton has had a rollercoaster ride over the past few years, but this Mac and iOS-user favorite is still forging ahead. An intuitive approach to email management still appeals to many people, and despite the fact that this is a paid iOS email app, it’s still gained many fans over the years and is considered the best email app for iOS by some of its fans.

The latest feature is called Tidy Inbox, and it intuitively organizes your email for easier management. However, there have been security concerns with Newton, and only HTTP is supported for message encryption. As an alternative iPhone email app, this is a great option for those who like to do things a little bit differently.  

Newton doesn’t collect any personal information for advertising purposes and maintains physical, administrative, and technological safeguards to preserve the integrity and security of all information collected through Newton.

Price: Free to download, requires $49.99/annual subscription

6. ProtonMail

For anyone worried about security, ProtonMail may be exactly what you’re looking for. The online world still poses a threat to email users, and even though Apple’s operating systems are historically extremely secure, ProtonMail gives you just that little bit extra protection.

End-to-end powerful email encryption methods ensures all your data and documents are safe, and an easy-to-navigate user interface makes managing secure email a breeze. ProtonMail is also open source and completely free to use, the ideal iOS email app for anyone who doesn’t want to shell out their hard-earned cash but won’t compromise on security.

If you want all the bells and whistles, though, you’ll need to look elsewhere.

Price: Free with Pro features starting at $5/month

7. Airmail

Another exclusive iOS email app, Airmail takes its cue from Apple Mail, delivering a slick user interface that will make Apple users feel right at home. Featuring 3D Touch, fast document previewing and native integration with many apps, it’s made for advanced email users who want to be more efficient.

Workflow customizations including snooze, push notifications, and iCloud sync gives you plenty of options for workplace efficiency, while for Premium users, you can also get 24/7 support. Finally, dark mode is included to give you that sleek Apple email app look on your iPhone or iPad.

8. Hey

Hey is a new email service from the team at Basecamp. Hey is part app and part email service combined into one. Hey offers an ‘Imbox’ that is designed to only show you the important messages, and it filters less critical messages for you to work on later. In Hey, all your attachments are organized together into an attachment library. 

Hey offers a lot of great benefits to help people manage their inboxes, but it’s going to be a non-starter for many due to its $99/annual subscription and the fact that you have to completely change your email address. 

Hey is a very secure service and uses Encryption at-rest, at-work, and in-transit, but not end-to-end because it’s challenging to do that with email. Hey is also conducting external security audits. 

Price: $99/annual payment, 14-day trial

9. Yahoo 

Yahoo is one of the original web companies since it has been around since 1994. Over the years, it’s evolved quite a bit from what it started as, and it’s lost much of its relevance from its high point in the early 2000s. Nevertheless, it’s still a popular email service for many people. The iPhone app has improved quite a bit in recent years and can now work with external email accounts like Gmail, Outlook, and AOL. 

Since Yahoo is a free service, it still relies heavily on advertising, though. For people who primarily use email to organize coupon alerts, manage shopping lists, and want to track their packages, it’s a pretty useful tool. If you use email for business or heavy personal use, other solutions will be better suited for those needs. 

Since Yahoo is an app from a major media company, it can generally be found secure, but be reminded that Yahoo is driven by advertising so your data will be mined.

10. Twobird

Twobird is a newcomer to our list of best email apps for iPhone. As Spike does, it brings a conversational approach to email, but it’s only limited to Gmail and Outlook accounts. If you use Yahoo or iCloud – you’ll have to look elsewhere for an alternative iOS email app or decide to use multiple email apps.

On top of email, Twobird also includes notes and tasks to beef up your productivity when on a mobile device. Twobird is from the team behind the popular notetaking app – Notability.

11. Spark

Spark email is built and maintained by Readdle, a popular iOS and macOS email developer. Other notable apps include PDF Expert and Documents. Spark includes some notable features such as Group replies, snooze, and scheduled send.

One of Spark’s most notable features is its 3rd-party app integrations. Using these integrations, you can send an email thread to your task app like Todoist or Omnifocus, including a link back to the message. 

Spark is available on all platforms including iOS and macOS. It does a web app or a Windows application, though.

Price: Free with upgrades for teams
