Best Email App for iPhone 2023

If you’re wondering, “What is the best email app for iPhone?”, this article is for you.
We’ve tested dozens and dozens of highly rated email apps from App Store and elsewhere and picked the best email apps for iPhone that stood out the most with their innovative features and a modern user experience.

What Makes a Great Email App?

If you search for email apps in App Store, you’ll be presented with an excruciatingly long list of email clients, management tools, and miscellaneous utilities. The question is how you distinguish best iPhone email apps from those that are merely good.

Well, there are several checkboxes that email apps must tick if they want to be truly excellent, starting with design and user experience.

Because we live in a fast-moving information era where cutting-edge technologies become obsolete seemingly in a blink of an eye, our time to learn new things is significantly limited. Best email apps for iPhone are so intuitive that you can simply pick them up and start using them without going through tutorials or reading how they work.

They are also designed with the latest usability principles in mind. Operations that take multiple steps in lesser email apps often take just one step in best email apps, and all important features are put front and center, so you never have to look for them when you need them.

Best iPhone email apps support all major email service providers, including Gmail, Outlook, Yahoo, and other POP3 and IMAP email services. Some also support Exchange, which is Microsoft’s proprietary alternative to the POP3 and IMAP application-layer internet standard protocols.

Some people believe that a free email app for iPhone can never be truly great, but our own experience tells us something else. Some of the best iPhone email apps we’ve tested are completely free and have been since they were first released. Others are free for a limited period of time so that you can thoroughly test them and decide whether they’re worth the price.

Best Email Apps for iPhone

The native email app in iOS, called simply Mail, is undeniably capable as far as native apps go, but it still pales in comparison with many third-party email apps available in App Store and elsewhere. We’ve tested many such apps and selected five that we liked the most.

1. Gmail

Price: Free + $1.99 per month for 100 GB of extra storage space or $9.99 a month per month for 1 TB of extra storage space.

Gmail is a free email service developed by Google and launched in 2004. While it’s possible to access Gmail from the web, you will do yourself a huge favor if you download and use the official Gmail app for iOS instead. The Gmail app provides real-time notifications, allows you to easily switch between multiple accounts, search your mail faster with instant results, and respond to Google Calendar invites right from the app, just to name a few of its many features.

With Gmail, you get 15 GB of free storage space, which is shared across all Google services, including Google Drive and Google Photos. Should you ever need more, you can purchase 100 GB of extra storage space for just $1.99 per month or 1 TB for $9.99 a month.

👍🏼   Pros:
  • Support for non-Google email accounts.
  • Automatic email filtering.
  • Multiple layouts available.
  • Seamless integration with other Google apps and services.
👎🏼   Cons:
  • No text customization.
  • Notification issues.

Outlook for iOS is sleek, gesture-friendly, fast, and packed with many surprisingly useful features that you don’t find anywhere else.

Outlook for iOS supports Microsoft Exchange, Office 365, Gmail, Yahoo Mail, and iCloud, but it works best with (including Hotmail and MSN), a web-based suite of webmail, contacts, tasks, and calendaring services from Microsoft. With, you get 15 GB of email storage space per free account, and you can get more storage space and an ad-free inbox by purchasing an Office 365 subscription.

Whenever you have a few minutes of spare time, you can open Triage and quickly read all new emails, which are presented as a stack of cards through which you can swipe with intuitive gestures.

All versions of Spark are packed with useful productivity-enhancing features whose purpose is to help users achieve and maintain Inbox Zero.

The developers of Newton Mail have studied what problems email users encounter most often and decided to solve them one by one.

Newton Mail has a feature called Read Receipts, which allows you to know who read your email and when. Unlike other similar email tracking tools, Newton’s Read Receipts work across all platforms on all email accounts.

Newton Mail can also automatically get useful insights about senders, giving you the sender’s job, organization, and social media profiles in a single click. On average, this feature alone can save you about 12 minutes of time per every new sender, according to Newton Mail’s developers.

Price: Free + $5.99 per month for a single Pro account.

What would it take to upgrade email for the 21st century? The people behind Spike think that the answer lies in instant messaging. Instead of grouping emails into endless threads that are difficult to follow because they contain useless information such as headers and signatures, it streamlines the email experience and makes it more conversational by allowing you to communicate with others just like you would with an instant messenger.

Because words don’t always cut it, Spike makes it easy to make voice or video calls right from the app. Thanks to Spike’s collaboration features and intelligent file attachment management, you can streamline your workflow and reduce the number of apps needed to get things done. Spike is free for individuals who want to use it with a personal email address, but employees are required to pay $5.99 per account per month for a Pro account.

  • Conversational approach to email.
  • Handy collaboration features.
  • Previews all common file types.
