The best email app: If until now you have only known the Gmail or Outlook apps and want to know new things, I invite you to take a look at the following best email app for Android. The best to give a new air of freshness to your personal mailbox.

1. AquaMail

AquaMail is one of those email clients that has been with us for years. It supports all kinds of email accounts, including AOL, Yahoo, Gmail, Outlook, iCloud, or Exchange, and the truth is that it has very good acceptance among Android users. A high score on Google Play and its more than 1,000,000 users give good faith to it.

It allows you to make and restore backups of our emails from the cloud (Dropbox, OneDrive, Box, and Google Drive) or through files. It has synchronization of contacts and calendar for Exchange and Office 365, allows you to use a different signature for each account, in addition to notifications and responses by voice for Android Wear, among many other functions. One of the best email managers, of all life.

2. Email Blue Mail

Blue Mail is another one of those top-rated email apps on the Play Store. With more than a million users, Blue Mail allows you to configure Gmail, Yahoo, Outlook, AOL, iCloud, Office365, Google Apps, Hotmail, and Live.com accounts, in addition to other mail service providers. We will be able to configure Exchange, IMAP, and POP3 accounts in a fluid and easy way.

It has a unified tray from where we can manage all our email accounts. It is compatible with Android Wear, has configurable menus, and a customizable dark color theme. Also, it has a lock screen to protect our private emails, a lot of extra functionality, and is 100% free.

3. Spark

If we have been Inbox by Gmail users in the past, and we were quite angry when Google decided to close the app, Spark may be just what we need. A complete email client focused on organization and teamwork.

Among its functionalities, it manages to achieve a certain order within the own mess of any inbox. It uploads the emails of real people to the first row so that we can see them before the rest and notifies us only of the emails of the people we know to avoid distractions. We can also use other advanced features like postponing emails, creating reminders, pins, doing smart searches, and more.

Also, it is an excellent collaborative tool:

  • We can invite friends and coworkers to discuss specific emails and threads.
  • It has a real-time editor to compose emails jointly between several collaborators.
  • It allows you to create secure links to specific messages or conversations that we can then share with other people.

In addition to Android, it is also available for iOS and Windows. A true gem.

4. Microsoft Outlook

One of the most used email apps today (more than 100 million downloads). Incredibly popular, especially in business and work environments, it supports Exchange and Office 365 accounts, in addition to including integration with Sunrise.

We can also use it with Gmail, iCloud, or Yahoo accounts and synchronize it with cloud storage services. It has built-in gestures for scheduling, deleting, and archiving messages and calendar management or the classic out-of-office assistant.

The Outlook email app still has some points for improvement, such as the default font size and reading of emails with the same subject. In any case, it is much friendlier than the desktop version.

5. Edison’s Email

This email client developed by Edison Software is one of the winners of last year’s Android Excellence Program. Highly acclaimed by specialized media such as The Verge (” The fastest email app “) or Android Authority (” Useful features and a great user interface “), Email is presented as the great relevant novelty in terms of sending and managing emails from the mobile or tablet.

It supports a large number of email providers and allows you to manage unlimited accounts. Besides that:

  • It incorporates an integrated, intelligent assistant.
  • Grouping by categories.
  • Compatible with Android Wear.
  • Control by gestures.

All this and more, in an application of elegant design and fast as it alone.

6. Gmail

We also cannot ignore this Gmail list. Probably the most used email app on Android devices with more than 1 billion installations. Since I’m surely not going to discover anything new talking about the qualities of the Google email client of a lifetime, let me tell you about Gmail Go.

Gmail Go is a new version of Gmail developed by Google, but much lighter. This makes it the ideal alternative for those devices that are a bit short on resources and need something lighter.

It features a smarter inbox, less spam (blocks it before it reaches the inbox), and 15GB of free storage.

7. Newton Mail

Newton Mail is a powerful email client known for its smart searches, its user interface, and its ability to integrate with other applications such as Pocket, EverNote, or OneNote.

Among its outstanding qualities, it offers the possibility of protecting our inbox with a password in addition to many other functionalities.

However, all this comes at a price: after the first 14 days of a free trial, the app becomes paid ($ 49.99 a year, or in other words, about $ 4 a month).

8. Mail.Ru Email

Although leaves a lot to be desired, the Mail.Ru mail app is one of the most popular and best-rated on Android. Its users highlight its ease of use and the possibility of being able to use multiple accounts centrally and simultaneously without eating too much.

Supports Microsoft mail services (Hotmail, Outlook, MSN Live, Office 365, Exchange). Gmail, Yahoo Mail, Orange Email, MixMail, iCloud, Mail.Ru -as not-, and Yandex, in addition to other services of Email with IMAP or POP3.

9. K-9 Mail

The most popular open-source email client for Android. It supports Exchange 2003/2007, IMAP, and POP3 accounts and includes the typical characteristics of any email client in use. It allows for labeling with flags, saving emails in the SD, PGP / MIME, signatures, and more.

If you are an advocate of free software, K-9 Mail is your email client.

10. Proton Mail – Encrypted Email

Proton Mail is the world’s largest encrypted email client, with over a million downloads. This app was created by CERN scientists in 2013, and since then, it offers PGP end-to-end encryption for Android users for free.

This means that the sender and the recipient can only read an email. Although emails are stored on a server, it is also encrypted, so even Proton Mail owners cannot access them. It allows you to send self-destructing emails, gesture management, and other features typical of any self-respecting email client.

11. TypeApp Mail

The TypeApp email client is ideal for those who receive a lot of emails a day. TypeApp groups them all together by the sender and then let you read them separately by scrolling. If we are looking for order above all else, this may be an app worth checking out. Supports Exchange, Gmail, Yahoo accounts, AOL, Outlook, Office 365, and more.

It also supports push Email with those services that support it. Another very interesting function is that it allows you to mark emails as “DONE” once they are managed. In this way, they disappear from the inbox, without the need to archive them by hand, through the use of smart filters.

12. myMail

myMail is another email tool that allows us to unify all our accounts in a single app. It supports Exchange, POP3, IMAP, and SMTP, and it has one of the easiest interfaces to use that we can know. It still has a few things to improve, but it’s usually really good.

Also, it is the mail application for anyone who has a short account at my.com (a subsidiary of Mail.Ru, the second-largest online company in Russia). Among its functions, it has customizable push notifications according to schedules, «moments of silence» for each account -to better combine work and personal life-, PIN protection, mail chains, and more.

13. GMX Mail

Another fairly popular email client on Android, which continues to receive constant updates today is GMX Mail. It has a cloud storage service called GMX MediaCenter, where we can save documents and multimedia files such as photos, videos, music, etc.

On top of that: PIN-protected emails, push notifications, and an instant messaging service called FreeMessage. It is completely free, although it offers integrated purchases for some additional services.

14. Nine

Nine is another great email application, especially if you are a lover of security and Outlook. It does not use any server or cloud service. It simply connects your device directly to your mail server.

It supports Exchange ActiveSync and has functionalities such as selective synchronization, being able to choose which folders we want to be synchronized with our mail server.

The free version has a trial period of 2 weeks, from there, if we are satisfied with the service, it will be necessary to go through the box.

15. Boxer

The last email client on the list is Boxer. A mail manager whose main virtue is its intuitive design and the use of gestures to navigate as smoothly as possible. This tool is a 3 in 1 since it allows us to control the mail, the contacts, and the calendar in a centralized way.

Its features include the use of massive actions, configurable quick responses, customizable scrolling gestures, and the availability of sending function. The app still has some edges to polish, but it is constantly updated and aims to be one of the great alternatives in the future.

Complementary Tools to Improve and Enhance Email Management

As we mentioned at the beginning of the post, there are some really useful apps for Android that work wonderfully as a complement to our regular email client. With them, we will obtain new functions that we will hardly see in ordinary mail applications. Don’t lose sight of them!


Cleanfox is an app that is responsible for automatically freeing us from all the spam, advertising emails, and newsletters that flood our mailbox. Normally, to unsubscribe from this type of Email, we have to request unsubscription manually.

With Cleanfox, however, we can automatically search for all email subscriptions stored in our Email. It is thus allowing us to unsubscribe and delete all those emails with a single click. Essential to do a good clean once in a while. Also, it is 100% free.

Instant Email Address

This great tool allows us to create temporary email accounts. Fully functional email accounts that we can use to send and receive emails, and which comes in handy for registering on platforms or services that require an email account in order to register.

It is also very practical if we do not want to give our real Email to a person (due to lack of trust or any other reason). Still, we need to provide a valid email address: a free, versatile, and highly recommended application.


As its name suggests, MessageLOUD is an application that is responsible for reading emails aloud (it also works with SMS, WhatsApp, Skype, and Facebook). A recommended tool above all to avoid problems or distractions while driving.

The application has a high rating of 4.2 stars on Google Play, although it should be clarified that it is a premium paid app ($ 1.99 / month). Of course, it has a 14-day trial period where we can use it and see if it is really worth the subscription.

And you who think, what is your favorite mobile email app? Do you know of any add-ons or additional tools that are worthwhile?

How does Your Email work?

Electronic mail was one of the first services that existed on the Internet, in fact. It was originally created for the exchange of information between universities (what do you say about the military. That never happened), and its operation is still very archaic in general, has changed very little in many years.

Email works as a client-server system. Whether from webmail or with a program, what we do is use a client that shows us the emails that have reached our mailbox and lets us send emails to other people. Then this client connects to a server that already does the dirty work.

Email Servers

Basically, there are two types of Email currently, the normal one, based on POP3, IMAP and SMTP, and those based on Microsoft’s Exchange. In this second, we will not focus since it is the Hotmail of a lifetime or is used only on servers of large companies.

Focused on normal mail, the reality is that there are two different servers, one that is in charge of sending emails, SMTP, and the other that is in charge of receiving and saving them in the mailbox, to which we will connect through POP3 or IMAP. The curious thing is that these two servers are completely independent, that’s why when you send an email from a client, if you later access it from a different one, you will not see it in the sent folder as it has no connection to the mailbox.

SMTP and E-Mailbox Operation

When you send an email, your client connects to an SMTP server, this one with the email address searches by DNS for which mailbox it corresponds to. Then when our client connects to the mailbox, it checks if there are new emails, and it depends on the protocol that we have configured. It reacts in one way or another. If we use the POP3 connection, what the client does is download the emails to our computer, deleting them from the server. This means that if we have several clients, we can only read the mail from the first to download it, although there is usually an option to leave a copy of the mail on the server.

This system is being deprecated in favor of IMAP. With the IMAP connection, what we do is synchronize the client with the mailbox, but without downloading the emails. This helps to have several clients knowing from each one what emails you have already read.

Email security

Emails are sent over the Internet in plain text format, making them especially vulnerable to eavesdropping by spammers. This is why it is highly recommended to use encrypted connections to the servers, which makes them practically impossible to read by strangers. Usually, almost all mail services are already secure, but it is interesting to note when configuring an Outlook or Thunderbird client that the connection to the server is secure.
