Best email apps for iPhone and Android

Hand pointing to email in the cloud

There aren’t many professions or activities today that don’t somehow involve using email in some way. Whether it's account logins, social media services, business applications, event invites or mailing lists, modern life just couldn’t function without email.

And with the volume of messages we receive nowadays, inbox-overload is never far away. But don't fear, our selection of mobile email apps – for Android, iOS and Windows Phone – will help you choose a service to keep on top of the messages that matter most.

Alto

Although Alto hasbeen developed by US email maestro AOL, the app supports the whole range of email providers including Gmail, Yahoo and of course Exchange for work emails. The app's focus is on keeping your inbox completely organised using Cards and Stacks that highlight the most important information including flight bookings, reservations, meetings and attachments meaning you don't have to trawl through your inbox to find out your priorities. Stacks can be organised around people, so just create a group for your team and all the emails will be presented in one organised place.

Blue Mail – Email Mailbox

Many actions and gestures are customisable; you can set the swipe functions to whatever suits you best, for example.

Boxer Lite

Publisher: Taskbox

Format: Android, iOS

Hop – email messenger

Publisher: Hopflow

Format: iOS

Price: Free

Hop is unlike other email clients in that it treats your inbox like it’s a messaging app, sorting your mail into a familiar left/right conversation view. Cleverly, conversations with friends and colleagues are given priority, while mail from other sources is kept in the background. The app is fast, with email exchanges happening in near-real time, just like SMS. Hop makes good use of long tap gestures to mark a thread as read instantly.

CloudMagic Email

Publisher: CloudMagic

Format: Android, iOS

Price: Free

A fast, uncluttered interface and some useful extras make CloudMagic worth considering, even if it doesn’t have quite the de-cluttering focus of its rivals. Emails are sorted into conversations. Swipe left on one to bin or archive the lot. In-message, tap on the Cards icon to send your email to a connected app, such as Evernote or ToDo. Adding multiple accounts is easy and you can attach files directly from online storage services.

Gmail

Publisher: Google Inc

Format: Android, iOS, Windows Phone

Price: Free

Google’s own email client comes preloaded onto many Android devices but it’s well worth downloading if you don’t have it. Despite its name, the app isn’t just for Gmail – in fact, it supports just about any type of account you can think of: POP, IMAP, Exchange, webmail and more. It has a unified inbox, with the ability to hide (mute) threads, label messages or archive emails with a quick swipe. It's best features is the ability to send large files (up to 10GB) by ‘inserting’ them from your Google Drive, rather than attaching them.

Inbox by Gmail

Publisher: Google Inc

Format: Android, iOS

Price: Free

Developed in parallel to Google’s standard Gmail app, Inbox takes the rather refreshing approach of treating your inbox more like it’s a to-do list. You can pin important items that need your attention, snooze messages that can be dealt with at a later date with a quick swipe and set yourself reminders. It might not replace your regular email client full time, but it’s definitely worth trying out if you’re a Gmail user. Inbox's best feature is it can automatically ‘bundle’ together emails of a similar type into categories.

Inboxcube

Publisher: Inbox Cube Inc

Format: iOS

Price: Free

Inboxcube flips the inbox on its head by sorting content by attachments and user-specified search fields, rather than individual messages. You set up ‘cubes’ for photos, videos, Word documents, Excel sheets, PDFs and links, and then app organises all the relevant messages that contain that content together, which you view directly from the app. Compatible with Gmail, Yahoo, iCloud, Office365, Exchange and other IMAP-based providers, Inboxcube shortens the sifting process for email attachments.

Microsoft Outlook

Publisher: Microsoft Corp

Format: Android, iOS, Windows Phone

Price: Free

A fully-fledged mobile version of Microsoft’s desktop Outlook program, rather than an app version of its Outlook.com webmail client, Outlook is a powerful email client with tightly integrated calendar and contacts. It’s designed for Exchange accounts but works with webmail and IMAP accounts, including Gmail, Yahoo, and iCloud. Its ‘Focussed’ inbox lets you swipe left or right to quickly archive a message or schedule it to reappear later when you have time to deal with it. The best feature is you can integrate cloud storage accounts (including OneDrive, Dropbox and Google Drive) for quick access to important files. However, POP3 accounts aren’t currently supported.

myMail

Publisher: My.com

Format: Android, iOS

Price: Free

Flexibility on a granular basis is at the heart of My.com’s pitch for its email app myMail, which allows you to receive push notifications for specific email accounts – regardless of whether your email provider natively supports this function. You can filter notifications based on folders, social networks, domains, or email addresses, and set a ‘silent mode’ for set times of the day. The clean-looking inbox also offers a customisable message list, powerful search functions and PIN lock support.

Nine – Exchange on Mobile

Publisher: 9Folders Inc

Format: Android

Price: £6.57

Nine is by no means the fastest or the simplest email app we’ve tested, but for Exchange users who just want to send and receive messages like they do at their desktops, this app is hard to beat. It has a powerful interface with filters and left and right swipe menus for quick actions, such moving or deleting a message. It isn’t free but there’s a free 14-day trial if you want to try it out. It’s one of the few mobile email clients that lets you compose messages with rich-text formatting.

ProtonMail

Publisher: ProtonMail

Format: Android, iOS

Price: Free

ProtonMail is pretty much the king of secure email apps. Founded in 2013 by CERN scientists, it uses either 2048-bit or 4096-bit encryption, and supports end-to-end encryption between ProtonMail users. You can also encrypt your emails with a password if the recipient doesn't use ProtonMail, and even set the messages to self-destruct after a certain period. Likewise, users can set a PIN which will wipe all sensitive user data after ten incorrect attempts. You'll have to sign up for a separate, specific email account, but it's a small price to pay for total privacy.

SolMail

Publisher: Kakao Corp

Format: Android

Price: Free

On top of collating all your inboxes in one, SolMail offers a superbly simple interface that’s ideal for mobile devices. Messages can swiped to be deleted or archived, viewed by conversation, and filtered. You can also decide which email folders you’d like to sync, and get notifications for specific ones. SolMail also comes with over 900 custom emojis. Reliability and regular developer support have earned SolMail accolades from media and favourable ratings from thousands of users.

Spark

Publisher: Readdle

Format: iOS

Price: Free

Spark aims to put you back in control of your email. There are two views – the standard Inbox lets you browse your email in chronological order, but the Smart Inbox organises your messages into groups with the very latest emails shown as notifications at the top of the list. Your devices’ calendar can be integrated, and you can link to cloud storage services and add attachments directly from them. Its best feature is tapping the EQ icon in the sidebar allows you to personalise the way Spark works to suit your tastes.

Triage: Email First Aid

Publisher: Southgate Labs

Format: iOS

Price: £2.29

Triage isn’t a replacement for your current email client – it’s best used alongside it to help you process your messages and declutter a busy inbox quickly and efficiently. Messages appear as a stack of cards. Flick a card upwards to archive the message instantly or flick it down to keep it for later. Tapping a card opens the full email. And that’s about all Triage does. There’s no push notification, but setup is quick and you can add multiple accounts. Triage only works with Gmail, Yahoo, iCloud, Outlook.com and IMAP accounts.

WeMail

Publisher: Kale Interactive

Format: Android

Price: Free

WeMail's aim is to make your inbox smaller, so it's easier to find messages with less scrolling. One way it achieves that is by threading emails from the same person into a chat view, so it's more conversational. It also pulls all attachments into a central hub, making it easier to find them without hunting out the original message, and has an advanced contextual search tool to make it easier to find the email you have in mind. And, if your email recipient also has WeMail, your short messages are displayed like IM such as WhatsApp, making arranging plans quick and easy - handy for emailing on the go.

VMWare Boxer

Publisher: VMWare

Format: Android and iOS

Price: Free

VMWare’s Boxer app is particularly tuned for enterprise use with mobility management and security features mixed into a consumer-grade user interface.

Boxer has a personal information management feature which uses a container style approach to handle the app’s management and security on both Android and iOS devices, which allows the apps to be managed by a company's IT department through the use of VMWare’s AirWatch or Workspace ONE services.

Features such as data leakage protection policies to help manage the sharing of certain files of data and allow the encryption of all email attachments, sit behind a user interface that can support custom gestures and enable the bulk editing of email messages.

Connectivity to cloud storage services like Dropbox and Google Drive is also included alongside built-in calendar functionality, which prevents the need for users to jump into a separate app, and the ability to customise new email sounds. Boxer also works with Microsoft’s Office 365 cloud-based productivity suite.

There are also some machine learning capabilities which can learn a user’s habits in the app and serve up folder suggestions based on their past activities, which should speed up the management of emails, especially if a user has multiple email accounts linked to the app.
