Emails are one of the most annoying things that we have to deal with and yet they are something that we cannot work without. We have to accept the fact that emails are here to stay for the foreseeable future. And if we cannot get rid of emails, it’s better to have a system which that let us deal with emails in a better and more efficient manner. One of the pillars of that system is a good email client. Over the years I have tested many email clients for both Android and iOS devices and I am going to share my favorite apps with you in this article. So, if you are looking for the best email app for you, here are the 12 best email apps for iPhone and Android that you can use.

1. Gmail

Let’s get the obvious option out of our way first. Gmail is Google’s free email service and most of us are using it in our daily lives. If you don’t have a professional email account, chances are that you are using Gmail. Apart from its email service Google also provides its own email apps for both iOS and Android with the same name, and I must say, it’s one of the best free email apps on the market. I love its straightforward user interface which makes the email readable at a glance. There’s also gesture support which lets you easily triage through your emails.

Install: Android / iOS (Free)

Another great email app for iPhone and Android that comes from a major tech giant is Outlook. Created by Microsoft, Outlook is the app that most of the business users use as their email client. While the app is available on both Android and iOS platforms, it is especially good on iOS, thanks to a more fluid and interactive design language. I love its “Smart Inbox” feature which gives me access to my most important emails first so I can reply to them at the start. I also love the swiping gestures that let me quickly schedule, delete, and archive emails.

Spark Mail is a free email client for iPhone and Android. I have been using Spark Mail on my personal iPhone for years and it has never let me down. The reason why I have stuck with Spark Mail for so long is that its design is both functional and pleasing to eyes. First of all, Spark Mail intelligently categorizes emails into two main sections which are Personal and Newsletter. Personal is the section which hosts the emails that you need to respond to while the emails in Newsletter section generally are ones which will end up in your trash. You also have the ability to pin important emails which will always remain at the top giving you quick access.

Install: iOS / Android (Free, Starts at $7.99/user/month)

Another great third-party email app for Android and iOS devices is the Blue Mail app. One of the biggest benefits of using Blue Mail is that it supports all kinds of email services so no matter which email service you are using, Blue Mail will work for you. When it comes to features, Blue Mail is no slouch. You get all the usual features such as support for swiping gestures, the ability to schedule emails, filters and search, signature support, customization user interface, and much more. Personally, my favorite feature of Blue Mail is its ability to deliver smart mobile notifications.

If you value your privacy over everything else then its time that you start using ProtonMail. The app brings end-to-end to encryption to your emails which means even the creators of ProtonMail cannot read your email even if they wanted to. In a world where popular email clients such as Edison Mail has been found to be reading user’s emails, you can never be too cautious. If you have even a shred of doubt about a free or even paid third-party email app, then ProtonMail is the answer for you. ProtonMail is an open-source project which means its code is available to be examined by everyone. The good news is that no one has found any security related risks with the app.

The email client supports almost all the email services so you are good to go no matter which email service you are using. I love the app’s user interface as it’s quite easy to navigate. The app makes it very easy to find important emails. You get access to all the usual features such as archiving and snoozing emails, creating filters, browsing attachment files directly from the app, a robust search feature, the ability to add labels, support for email threads, and more.

One of the highlights of this app is that it uses OAuth authentication to sign in to Hotmail, Gmail and Outlook accounts which do not request users’ credentials. Instead, access to users’ data is acquired directly from Microsoft and Google’s servers which ensures a secure e-mail login. Overall, I quite like this app and suggest that you try it out.

Nine Mail is a great third-party email app for Android and iOS devices for business users. The email client supports direct push synchronizations using Microsoft Exchange’s ActiveSync technology which allows it to access the emails almost instantaneously. What I love about Nine Mail is that it brings email, contacts, and calendar at one place. I also love the app’s user interface which is both beautiful and practical. There’s also a dark mode which helps in those late night email sessions. Other features of the app include support for multiple accounts, push notifications for folders, automatic setup for supported email services, Full secure HTML support, and more. I think, if you are looking for an email client from the perspective of a business, you should give it a try.
