Starting off with the most popular and top email app for iPhone & iPad, i.e. Gmail. The app is free, easy to use, and has a clean UI. It also doesn’t come with ads. On the other hand, it not only supports Google account but also Microsoft Outlook, iCloud, Yahoo, and other popular services. Plus, you can easily switch between accounts or view all mails under one tab. It also supports customizable swipe gestures through which you can archive, delete, snooze, or even move your email instantly with one swipe.

And if you are a Gmail user, then you can also schedule your email to any date or time. Furthermore, if the mail you are about to send is sensitive, then you can also use Confidential Mode, through which you can set expiry limits and require a passcode for the recipient to access the information.

Microsoft Outlook is another best email app for iOS and iPadOS. As the name suggests, it is a standalone app for Outlook mail. However, you can log in with other email providers such as Gmail, iCloud, Yahoo, Exchange, and more. Besides that, it has many cool features in its arsenal. That includes Focused Inbox, which displays only the important emails and remaining emails are moved to Other Inbox.

Also, the Calendar in the Outlook app is deeply integrated so you can easily create or manage events or appointments from any email provider within the app. Another cool feature is that you can link cloud storage services directly to the app, so you can access files from Dropbox, Google Drive, OneDrive, and Box.

You can also customize the appearance of the app and secure your emails by enabling Touch ID or Face ID. There is one feature that you will hardly see on any email apps, i.e. Do Not Disturb. This feature can automatically mute email notifications of individual or all accounts at the scheduled time.

On the other hand, the Outlook app has all the usual features that are common in many email apps such as personalized notifications, signature, swipe gestures, Siri shortcuts, and so on.

If the above two apps dint impressed you, then I bet the Edison Mail app will. One of the coolest and useful features you will get in the app is the option to unsubscribe from annoying newsletters with one tap. On top of that, with the help of an assistant, you can even get alerts on upcoming travel, package arrival, bill due, calendar events, and more.

Just like Microsoft Outlook, here too you will get a focused inbox feature that will automatically filter out irrelevant emails and will display only important emails. Furthermore, you can even customize the text message as per your need and create templates so that you never have to re-write the same message again & again.

With dozens of features, BlueMail is a good pick if you have multiple email accounts. It works with many email platforms such as Gmail, Outlook, Yahoo, iCloud, and even supports IMAP, POP3, and Exchange. The app also comes with Unified Folders, where all your emails will be shown in one place.

The coolest thing in the app is that while creating the new email, you change the text to bold, italic, & underline. In addition to that, you even get the option to change the font style and size. Furthermore, just like Microsoft Outlook here, also you get a customizable DND feature to mute email service notifications so that you can focus on other important work.

BlueMail app also covers some of the basic features such as dark mode, swipe gesture, app unlock via passcode, Touch ID, or Face ID, signature, quick replies, and many more. Also, if you own a Mac that comes with the M-series processor, then you can also install the BlueMail app in it. Altogether, BlueMail is a good email app for iPhone & iPad and you may consider it.

5. Spark

Spark - Free Email App

Ratings (IN)4.7

When it comes to design & functionality, the Spark Email app can give tough competition to many top email apps on this list. In the app, you will find all the primary features like support for multiple email providers, customizable swipe functions, push notifications, Touch ID/Face ID unlock, undo sent mail, and more. You also get Wear OS support, a dark mode, quick replies, and other customization features.

Spark app has many unique features in its arsenal that are not only useful but also free. That includes integrated calendar support, schedule email, customizable text, email snoozing, and so on. Additionally, you also get the Smart Inbox feature which smartly organizes all your emails into cards like people, notifications, newsletters, pins, seen, and shared drafts.

Also, having so many features for free still, you will not see a single intrusive ad in the Spark app which makes it one of the best apps for email on iPhone & iPad.

6. Yahoo Mail

Whether you use the Yahoo email service or not, it doesn’t matter. Yahoo Mail will still support other email providers, such as Google, Outlook, Office 365, and AOL. The design of the app is simple and easy to use. All the useful features are available right at your fingertips. There is also a dedicated Today tab that will provide you with the latest news and weather reports of the current location.

Like many popular email apps here too, you can unsubscribe spam and junk mails in one tap. In addition, it can also fetch Deal emails, which will notify you when it is about to expire, and with Travel view, you will be able to see flight information like gate changes, delays, and even cancellations in an organized manner.

Other than that, you will get all those usual features like app lock, swipe actions, themes, notifications, conversations, and more. Even now, if you are not sure whether to install Yahoo Mail or not, then maybe 1000 GB of free cloud storage might change your mind. All in all, Yahoo Mail is one of the best iPhone email apps on this list and you will not be disappointed with its service.

Speaking of service, you can also get Yahoo Mail Pro, which will provide you an ad-free mail and priority customer support at $0.99/month or $9.99/year.

7. Newton Mail

Newton Mail - Powerful Email App
Size214.3 MB
Ratings (NZ)4.6
PriceFree, In-App Purchase

Newton Mail is a powerful email app that literally offers everything a user might need. It is available for iPhone, iPod, iPad, and Mac. Furthermore, it supports all the popular email services and displays all of them in a unified inbox. It also has many useful features like a passcode lock, undo send, app badge count, dark mode, swipe actions, send later, and much more.

There are 2 features I love the most, one is Tidy Inbox, and the other is Read Receipts. In Tidy Inbox, you can check Newsletters and Emails from Social Media and any new emails from these categories will skip the inbox and go straight into the new folders under Low Priority.

On the other hand, with the Read Receipts feature, you may opt to receive a notification when the recipient reads or click your mail. I think this one feature might be powerful enough to drive many people to install Newton Mail. However, it is a subscription-based service that comes with 14 days of a free trial and later you can pay $91.99/year to continue the service.

8. Airmail

Airmail for iPhone & iPad

Ratings (US)4.5
PriceFree, In-App Purchase

Airmail is a freemium email app with many awesome features. It has support for all the primary email providers, including Google, iCloud, Exchange, Yahoo, and more. Also, you can view all your emails from multiple accounts in one unified inbox. On top of that, while composing the mail, you can change the format of the text to bold, italic, underline, list view, etc. Furthermore, you can even change the font style and color.

Also, just like BlueMail and Newton Mail here too, you will get support for Mac devices that have macOS 11 and M series chipset.

You will also get plenty of free features such as undo mail, dark mode, swipe gestures, app locker, signature, templates, and much more. However, if you want advanced features, then you have to subscribe to Airmail Pro that costs $2.99/month, whereas the yearly plan is priced at $9.99. Some of the features of Airmail Pro are:

  • Yahoo 2-factor support
  • New themes
  • Apple Pencil support
  • Send later
  • Privacy mode
  • Agenda Integration
  • Premium support and many more.

9. ProtonMail

ProtonMail - Best Secure Email App
Size155.7 MB
Ratings (CA)4.4
PriceFree, In-App Purchase

Privacy has become a major concern for many people around the world, which is why you need a good email provider with top-notch security. That’s where ProtonMail comes in. It provides encrypted email, which is virtually impossible for anyone to read except the sender and the recipient. Not even people from ProtonMail can decrypt and read your emails.

What’s more, you can send password-protected emails to non-ProtonMail users and even set timers for messages to self-destruct after sending. You will also get some basic features such as signature, auto show images, swiping gestures, and app locker (PIN/Touch ID/Face ID).

You will not see fancy things that are common on the majority of email apps such as themes, support for multiple email services, send later, Siri shortcuts, 1-click unsubscribe, calendars, etc. But if you are ready to compromise on ease of use and versatility for end-to-end encryption and security, then there is no doubt that ProtonMail is the best secure email app for iPhone & iPad.

10. Apple Mail

Apple Mail - Free Email App

Last but not least, we have Apple Mail. It is the most basic email app on this list and also the default email app on iPhone and iPad. Over the past, it has improved a lot, but still, it lacks many advanced features that are found on other popular email apps.

However, you will get few essential features like multiple email account support, which includes Yahoo, iCloud, Outlook, Google, or any other POP or IMAP compatible service. In the app, you can also change the style, size, and color of the fonts along with the format of the text to bold, italic, underline, bulletin view, numeric view, and so on.

So if you need an app only for sending and receiving emails, then Apple Mail is one of the best mail apps for iPhone and iPad.


Well, that’s the end of our list of the best free email apps for iOS and iPadOS in 2021. So whether you need an app just for casual mailing or you are a working professional who needs a wide range of features, you will probably find one in this article. Personally, I use the Apple Mail app on my iPhone as I prefer a simple design with basic functionality and an ad-free experience. On the other hand, you might have different preferences, so depending on your requirement, choose the right email app.
