Best Email App To Try In 2026
When Raymond Tomlinson, who is widely known as the Father of Email, implemented the first email app in 1971, he probably couldn’t even imagine that most people would carry infinitely more sophisticated email apps in their pockets. If you’re curious to know what is the best email app in 2026, you’ve come to the right place because this article features the very best the Google Play Store and the Apple App Store have to offer when it comes to email.
10 Best Email Apps
1. Gmail (Web, Android, iOS)
It’s no surprise that one of the most capable free email apps comes preinstalled on most Android devices. When Google launched Gmail in 2004, it reshaped personal email by offering far more storage than its rivals and one of the slickest experiences anyone had seen at the time.
Beyond Android, Gmail is also available on iOS, and it handles non-Gmail addresses too, including Outlook.com, Yahoo Mail, and any other IMAP or POP account. Google keeps adding features, but the app already does plenty even as it stands. You can schedule messages, unsend them, set an expiration time, work offline, and even let Google’s AI help draft your emails.
- Comes default on most Android devices.
- Works with non-Gmail addresses.
- Organizes conversations into threads.
- Smart filtering options.
- Free version shows ads in the Promotions and Social tabs.
- Data is used for personalization, which raises privacy concerns for some users.
- The 15GB of free storage is shared across Google services.
2. Aqua Mail (Android, iOS)
If you like to tinker with your tools, Aqua Mail is worth a look. This highly customizable client works with all the major providers, including Gmail, Yahoo, Hotmail, FastMail, Apple, GMX, and AOL, and it ties into a wide range of third-party services to deliver features many other apps don’t.
For instance, you can link it to your cloud storage to back up your messages, compose emails with advanced formatting straight from your phone, or assign a separate signature to each account. Keep in mind that the free version caps you at two accounts. Once available only on Android, Aqua Mail now offers an iOS app as well, so more users can give it a try.
- Fast and intuitive.
- Integrates with Tasker.
- Supports cloud storage services for backup.
- Works great with Gmail.
- The Pro version costs money.
- Max 2 accounts with the Free version.
- The free version adds a promotional signature to outgoing emails.
3. Microsoft Outlook (Android, iOS, Windows, macOS)
Microsoft’s $200 million purchase of an app called Acompli in 2014 made its intent to compete harder with Gmail clear. The resulting mobile app, Microsoft Outlook, quickly became one of the leading mobile email clients and still performs well on Android and iOS, with desktop versions available for Windows and macOS too.
Its signature feature is the Focused Inbox, which keeps your important messages front and center by tucking away marketing emails, subscriptions, and obvious spam. Outlook connects with Microsoft Exchange, Microsoft 365, Outlook.com, Gmail, and Yahoo Mail, and it’s free to use.
Outlook also integrates Microsoft's Copilot assistant, which can summarize long email threads, draft replies, adjust the tone of a message, and help prioritize your inbox. The deeper Copilot features in the Outlook apps require a Microsoft 365 subscription, or the Copilot add-on for business accounts, and AI usage limits apply.
- Focus Inbox makes it easy to get things done.
- Clean user interface.
- Built-in calendar.
- Can occasionally sort messages into the wrong place.
- Limited customization compared with some rivals.
- Some advanced features require a Microsoft 365 subscription.
4. ProtonMail (Web, Android, iOS)
After a run of privacy controversies around Google, some users have gone looking for an email service that respects their privacy and doesn’t scan message contents for advertising. Founded in 2014 by Andy Yen, Jason Stockman, and Wei Sun, with roots at the CERN research facility, Proton Mail (formerly ProtonMail) has become a go-to choice for privacy-minded users, offering reliable end-to-end encryption and servers based in Switzerland. Accounts can now use @proton.me addresses alongside the original @protonmail.com.
Unlike many encrypted email services, Proton Mail is surprisingly easy to use, and its free Android and iOS apps let anyone set up an encrypted mailbox in just a few taps.
- End-to-end encryption.
- Modern user interface.
- Free.
- Third-party email client support requires a paid plan (via Proton Mail Bridge).
5. Triage (iOS)
Triage stands apart by skipping the long list of flashy features and third-party integrations. Instead, it gives you a stripped-down experience built to clear new email as quickly as possible.
Open the app and your unread messages appear as a stack of cards. Flick one up to archive it or down to keep it, and tap a message when you want to forward it or fire off a short reply. Triage works with Gmail, Yahoo, iCloud, and most IMAP services, which makes it a handy option for anyone who has struggled to keep an inbox under control.
- Great for busy people.
- Simple to use.
- Most IMAP services are supported.
- Only for iOS devices.
6. Edison Mail (Android and iOS)
Edison Mail brings all your accounts together in one place. As messages arrive, its built-in assistant sorts each one into the right category, so they’re easier to find later and your inbox stays tidy.
You can block unwanted senders with a single tap, and the app makes it easy to unsubscribe even from junk mail that lacks an unsubscribe link. Messages you can’t get to right away can be snoozed and brought back at a more convenient time.
Recent versions include Dark Mode, which helps reduce eye strain when you’re reading or writing late at night. Edison Mail isn’t monetized in the usual way: instead, it collects user data and shares it with third parties.
- Reduces spam.
- Support quick responses.
- Configurable notifications settings.
- Unified inbox.
- Collects user data.
7. Blue Mail (Android, iOS, Windows, Linux)
Blue Mail, made by Blix, is known for a feature called Share Email, which lets users communicate through public addresses without revealing their private ones. Blix has said Apple copied the feature and later removed Blue Mail from the Mac App Store, cutting the developers off from an important source of revenue.
Either way, Blue Mail remains available on Android, iOS, Windows, and Linux. Whichever version you install, you get the same core features, including smart push notifications, advanced organization options, an integrated calendar, a dark theme, and a unified inbox.
It supports all the standard protocols, including IMAP, Exchange, ActiveSync, and POP3, so you can connect just about any account. Blue Mail also relies on industry-standard security technology to help keep your data protected.
- Supports multiple email providers.
- Private email communication.
- Beautifully designed.
- Smart push notifications.
- Groups emails by people.
- Occasional sync issues.
8. Nine (Android)
Plenty of professionals would struggle to get through a day without an app that pulls all their accounts into one place. Nine keeps your email in sync while also giving you quick access to your calendar, tasks, and contacts, so you can stay productive wherever you are.
It supports both IMAP services and Exchange servers. Through Exchange ActiveSync, it connects directly to your mail server and keeps all data on your device, which appeals to users focused on privacy and security.
Unlike most apps on this list, Nine isn’t free. You get a two-week trial, after which a one-time license costs $14.99 to keep using it.
- All-in-one solution for mobile business.
- Robust security.
- Integrates email with calendar, tasks, and notes.
- Relatively expensive.
9. Spike (Android, iOS, Windows, macOS)
Next to modern messaging apps like Facebook Messenger, WhatsApp, or Telegram, most email apps make it hard to follow a conversation and reply quickly. Signatures and quoted text often take up most of the screen, leaving little room for the message that actually matters.
Spike tackles this with a conversational take on email. It strips away the clutter and leaves the substance of each message, so the app feels more like a chat client than a traditional inbox. When text isn’t enough, you can start a voice or video call and drag and drop any file you want to share.
- Supports all major platforms.
- Email for the IM generation.
- Automatically sorts emails by priority.
- Restrictions for free users.
10. TypeApp Mail (Android and iOS)
TypeApp Mail takes a people-first approach, grouping messages by sender to keep your inbox organized. If a colleague tends to send ten separate emails to make a single point, the app bundles them together so you can read the lot as one conversation just by tapping their name.
Beyond that smart organization, TypeApp Mail offers customizable push notifications, email reminders, colored themes, and support for wearables. It connects to any IMAP, Exchange, or POP3 account, though it can become a memory hog once you add a lot of them, which is worth keeping in mind on an older phone with limited memory.
- People-centric features.
- Group mail.
- Rich text editing.
- Scrollable widgets.
- Can be a memory hog.
Conclusion
The right email tool comes down to what you need and the devices you use. If you want something that’s ready to go out of the box, Gmail and Microsoft Outlook are safe, full-featured choices. Privacy-focused users may prefer Proton Mail, while those who value speed and simplicity could lean toward apps like Triage or Spike. Tinkerers and power users have options like Aqua Mail, Blue Mail, and Nine.
Take stock of your platforms, your budget, and the features that matter most to you, then pick the app that fits the way you work.
