You are a busy professional on the road, so you deserve an email client that keeps track of you. "Mail" on iPhone was not always the best option, but thanks to iOS 13 it feels like a completely different app. That said, there are plenty of alternatives that offer a different experience. Better yet, these apps are free . You don't have to spend a cent to try them out yourself.
Are you looking for an app that intelligently sorts your email? How about one that protects you against sketchy senders? Maybe you just want an email app with a good widget or support for themes. These functions and more can be found in the clients below and they all work with most e-mail accounts. Take a look!
Table of contents
- IMAP support: Most common e-mail services such as Yahoo Mail, Google or iCloud are Internet Messaging Access Protocol (IMAP) accounts. Chances are that if you use an email from a popular service, your account drops to IMAP.
- POP3 support: Unlike IMAP accounts, which store your e-mails continuously on a server, POP3 (Post Office Protocol 3) accounts download and delete those e-mails from the server. These accounts are not as popular as IMAP and many email applications do not support them. So if you have a POP3 account, you want to make sure that the app you choose is compatible.
- SMTP support: Otherwise known as Simple Mail Transfer Protocol, these accounts usually only send files to another source and are not involved in receiving messages themselves. If your account works with SMTP, you want the e-mail client to support this.
- Smart Inbox: A Smart Inbox sorts your e-mails to give you a clear picture of what is important. They differ from app to app, but ideally a Smart Inbox displays personal or important emails at the top of your inbox and then groups less important emails such as newsletters or notifications in a separate section, or keeps them completely out of the inbox. In short, it provides a much more focused e-mail experience.
- Bundles: Bundles are similar to a smart inbox, but work differently. Bundles group your emails by type into specific folders, or even as a combined email. For example, bundles can group all your email confirmations into one folder in the sidebar of your email app, allowing you to organize your content in a new way.
- Schedule emails: If you need to send an email to a time when you can't access your iPhone, you want an app that lets you schedule emails. That way you can choose a later time when your email will be sent, and rest assured that it will be where it needs to go.
- Snooze emails: Afraid that you will forget an email in your inbox? Snooze it! You can set a time to be notified of this e-mail in the future so that you can respond correctly. Or you can just snooze it again.
- VIP mailbox: A VIP mailbox only displays emails from contacts that you have labeled as VIP & # 39; s. It provides a much more targeted inbox experience, because you only see emails from senders that you know are important to you.
- Number of swipe actions: In most email apps on iOS, you can swipe left or right via an email to open a set of controls, such as answer, lock, delete, or mark as read . These promotions can make interaction with your inbox much faster, so the more promotions to choose from, the better.
- Select all: We have investigated areas in each app where you could select all emails. These areas include mailboxes, folders, and search.
- Quick selection Multiple emails: Included in iOS 13, quick selection allows you to immediately start selecting items with a swipe with two fingers.
- Search for attachments: While searching, you can use the apps to filter for attachments. Some apps may have a specific option for searching for attachments, while you can type a file type with other apps.
- Bulk removal from search: With the app you can delete multiple emails while searching.
- Hide draft for multitasking: Apps with this feature allow you to minimize your email drafts so that you can continue to work in the app without actually closing your draft.
- Widgets: iOS widgets appear on the left side of the lock screen and the home screen on your iPhone and they display the most important information about the app in question at a glance.
- Smart notifications: As with a smart inbox, smart notifications only send you notifications for important emails, either by the person or subject of the email. Ideally, the app automates this process, but with some apps you can manually adjust the notification settings to create your own "smart" alerts.
- Fast answer from lock screen: With Fast answer you can respond directly to an e-mail on the lock screen, without having to start the app itself.
- Save frequent searches: You could also see this as your e-mail search history.
- Flags: Some apps call these flags, others pins. Either way, with this tool you can mark emails as important. With some apps you can even set multiple colors for flags, which can be useful to quickly distinguish between important messages.
- Mute conversations: With some apps you can mute email threads, just like a chat in Messages or Messenger.  Rich Text Formatting: If the app allows you to change your fonts, text size, color, etc., it supports rich text formatting or RTF.
- Teams: Think of teams as groups. This feature allows users who all use the same e-mail app to chat, collaborate on e-mail, etc.
- Templates: Does the app support the creation of e-mail templates?
- Signatures: The app must allow you to create and save email signatures.
- Supporting the dark mode of iOS 13: Although many apps have had a dark mode for quite some time, we are looking for apps that support the system-wide dark mode of iOS 13. That means that the app will change the theme depending on the currently set system theme.
- Custom theme: In the same vein, we are also looking for apps that allow you to ignore this feature and choose your own theme.
- Siri shortcuts: With Siri shortcuts you can quickly perform tasks and activate app functions at the touch of a button or a Siri request.
- Adjustment of warning sound: We do not want to be stuck with the same sound over and over again. We are looking for apps with which we can change these warning sounds.
- Unsubscribe in-app: Email in 2019 means a party of unwanted email. That's why the ability to unsubscribe from emails directly in the app is so powerful.
- Customizable browser options: When you open a link in an email, it is nice to have options for which browser the page is displayed.  Block Trackers: Opening an e-mail is not always a one-sided operation. Some messages are peppered with trackers, usually an image that returns to the sender when you have opened the message.
- Undo Send: Oops! Did you not want to send that message yet? Some apps give you a small time window to undo a sent message, allowing you to save yourself for a host of embarrassing situations.
- Blocking addresses: With some apps, you can block specific e-mail addresses, ideal for removing your inbox from unimportant senders.
- Encrypted messages: Privacy and e-mail must go hand in hand, but often not. That is why it is fantastic if an e-mail app offers encrypted messages that protect your e-mail only on your device.
- Last updated: We did not include this item in our final score because all apps on this list were recently updated, but it is always good to know how regularly your apps are maintained by their developers.
- Select preferred language: In iOS you can set preferred languages in Settings -> General -> Language and region to use everywhere Your device. This then opens options with many apps for selecting a preferred language.
- Filters: Filters make it easier to see the content that you actually want in your inbox. Options can only be today's emails, emails with attachments, unread emails, etc.
- Full-page screenshots: In iOS 13 you can take screenshots that cover the entire page of your app, even if you can't see everything on the screen. This feature currently appears to be limited to iOS apps in stock, but we hope to open it to third-party apps in the near future.
- Quick Actions: Given that these apps are iOS enabled, it's nice to see when developers go one step further to include support for quick actions. In iOS 13, this includes examples and menus that are activated by 3D Touch or Haptic Touch. That said, apps that use different functions for 3D Touch and long press are now limited on non-3D Touch iPhones, the iPhone 11, 11 Pro and 11 Pro Max.
- Face ID / Touch ID Security: If you want an extra layer of protection for your e-mail, use an e-mail client with Face ID or Touch ID protection. That way, potential intruders cannot access your e-mails without a scan of your face or fingerprint.
- Calendar integration: Certain customers integrate your calendar (& # 39; s) directly into the app, allowing you to avoid having to jump between apps to complete time and date related work.
- Integration of third-party apps: These clients are built to work directly with third-party apps in the app, simplifying your workflow.  How we chose these apps
To limit the field, we did not allow email apps with user ratings below 4.5 stars in the App Store. Although reviews can be subjective, we found that apps above 4.5 stars are usually worth watching for the best apps of their kind.
In addition to simply trying out each application, we looked for specific functions and options that would help create an ideal email client. There is of course no perfect app, but these important points gave us a more subjective way to compare the different apps we tried. That said, here's how the top five ranked.
Spark is an excellent app for people with multiple e-mail accounts to sort through. It has the most features on our list and has some of the most intelligent options anywhere in the App Store. No app is perfect, but if there is an app that can do almost anything, it's Spark.
However, if you are looking for POP3 support, Spark may not be the right choice for you. Although the app supports many popular e-mail accounts, as well as IMAP and SMTP, POP3 is simply not included.
Spark & # 39; s "Smart Inbox" separates all incoming emails from your connected accounts into three categories – Personal, Notifications, and Newsletters. Personal appears at the top of the app, giving you a clear overview of the emails that require your immediate attention. Notifications range from new sign-up notifications from Google to shipping confirmations from Amazon. Newsletters can contain real e-mail newsletters that you sign up for, but you will probably also see advertisements and unwanted e-mail in this section.
Spark also contains many adjustments. You can choose which of the above folders are displayed in your Smart Inbox, and whether they are sorted into individual folders by email account or all merged into one folder. It's hard to go back to an old way to do email after using an app like Spark. You start ignoring something and not in your personal folder (because so much of what ends up in the other two folders doesn't matter).
Unfortunately, Spark does not integrate "bundles" in its e-mail service, where multiple e-mails of the same type be collected in one e-mail. It also has no VIP mailbox, but the "smart" functions are so good that you may not even notice it.
On the other hand, you can both schedule an e-mail to be sent at a later time, and can snooze e-mails for later viewing. You can set a reminder if you do not receive a reply from your recipient on a specific date.
Spark supports four swipe actions at the same time, two on each side of an email. You can adjust any action to any action you want, so you can read and sort e-mail as quickly as possible. It also offers "Select All" as an option in mailboxes, folders, and search, but does not support the iOS 13 speed-dialing function. Although there is no attachment filter when searching, you can easily search for attachments by typing the file type.
