Apple Mail

email app on iphone

 

 

  • Pre-installed email app on your iPhone, iPad, and Mac
  • Easy to use with intuitive interface
  • Full support for iCloud
  • Secure and reliable
  • Lacks advanced email functionality

 

The de facto email app for Mac, iPhone, and iPad, 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 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.

 

 

Outlook

  • Great iOS email app for business users
  • Tried and tested
  • Microsoft 365 and OneDrive integration
  • All major email providers are supported
  • May be too expensive for some people

 

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.

 

 

Spike 

email app on iphone

 

 

  • 21st century email app for iPhone and iPad
  • Seamless combination of email and instant messaging features
  • Powerful collaborative notes and tasks
  • Multiple email addresses
  • Easy access to most popular cloud services

 

Spike integrates a host of useful features directly into your iOS email app, providing the ultimate, unified workspace. Priority Inbox keeps all conversations with your most important contacts front and center, and an all-knowing Calendar is easily accessible on the same screen as your inbox – so you never miss an appointment and can reference it without switching screens or apps. Encrypted Email Messaging ensures the integrity of your inbox remains top-notch, and you can easily manage attachments with Spike’s Advanced Search. 

 

In addition to this, collaborative Notes and Tasks help you and your team work together seamlessly, while Practical features such as File Manager allow you to preview your files directly in line with your message. You can also easily manage multiple email addresses from your inbox, as well as connect directly to your favorite cloud provider so you have all your work at your fingertips.

 

 

Gmail

email app on iphone

 

  • Ubiquitous email app for iOS
  • Recognizable user interface
  • Excellent notifications and reminders
  • Multiple email addresses supported
  • Easy access to Google Calendar and Drive

 

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 or list 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.   

 

Newton

email app on iphone

 

 

  • Ideal iOS email app with intuitive email management
  • Snooze and send later features
  • Clean user interface
  • Interesting past with uncertain future
  • Expensive for some people

 

Newton has had a rollercoaster ride over the past few years, but this Mac-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.

 

The latest feature is called Tidy Inbox and it intuitively organizes your email for easier management. However, there have been security concerns in the past 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.  

 

  

ProtonMail

  • Ideal iOS email app with increased security
  • Powerful email encryption
  • Simple user interface
  • Can be a little basic for certain users
  • Open source

 

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 email encryption 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.  

Airmail

  • Recognizable iOS email app 
  • 3D touch passwords
  • Slick user interface
  • iCloud sync
  • 24/7 support for premium users

 

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 give 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.
