Your path to a focused and securely encrypted inbox.

Having an email client installed on your Mac can make a huge difference for your productivity. After all, your web browser is a portal to distraction, and any time you boot up Chrome or Safari to check on your inbox you’re in danger of losing at least 10–15 minutes to reading the news, browsing Facebook, or going down a “wiki-spiral.”

That said, not every email client is built the same. While macOS comes with the Apple Mail app by default, it might not necessarily be the best fit for your needs.

The best email clients are no longer just about sending emails, but instead as much as integrating into additional software and apps. Gmail, BlueMail, and Newton Mail are probably your best bets out of the 11 options considered. 'Incredibly fast, advanced & predictive search ' is the primary reason people pick Gmail over the competition. This page is powered by a knowledgeable community that helps you make an informed decision. Take note there are two parts to do this: 1) Mail App Settings and 2) macOS settings. We will go over both and show which of all the settings are required and which are not. Here’s what you need to do in your Mail app settings: Go ahead and click your Mail app, then click on the Preferences option and then General option.

Best Email Apps For Mac 2020

So what’s the best email app for Mac then? Depends on what you do. You might be a power user, comfortable with running macros to make the most out of your email experience, or you might just want something that works out of the box without having to fuss with settings. Security could be your top priority if you work with sensitive materials, or you might just need to easily manage multiple accounts.

Whatever the case, there are a few things to keep in mind when evaluating all email clients: How fast is the setup process? How easy is it to use? Is it secure? What are the sorting options for your inbox? Is it nice to look at?

Let’s sift through some top email apps using this questioning framework.

Apple Mail: Best email client for Mac by default

What makes Apple products great is also what limits them: because Apple needs to make apps that are so easy to use that anyone can use them, much of what they produce is quite basic in functionality. Which is fine — just make sure you know what you’re getting with the Apple Mail app.

You definitely get clean, user-friendly design that’s in line with all the other Apple software. In addition, you get outstanding integration with macOS and iOS, including the use of the Notification Center and the ability to send emails via the Share function in other apps.

Although adding multiple email providers, including iCloud and Gmail, is easy — there have been some bug reports around using Microsoft accounts, such as Hotmail or Live. Maybe the old Apple and Microsoft feud is not over yet?

In step with the times, Apple Mail app makes it effortless to add emoji to your emails from the shortcut bar right in the composing email window.

Honestly, for most people, the Apple Mail app will absolutely be enough. However, if you’re the kind of person who has a lot going on in their inbox, there are not too many ways to filter through all the messages quickly and pin down important conversations, or simply delete unwanted mail.

What’s great:

  • Clean design

  • Easy-to-use Mac mail

  • Fantastic Mac and iOS integration

Not so great:

  • A history of bugs with Microsoft accounts

  • Lacking high-powered organizational tools

Mozilla Thunderbird: Best free email client for Mac power users

Perhaps most widely known for their web browser, Firefox, Mozilla’s other major product is their email client, Thunderbird. Hailed as the best free email app on the market at various points throughout its long history, where does Thunderbird stand in 2020?

Unfortunately, Thunderbird’s design shows its age. Blocky and utilitarian, it’s quite a bit uglier than most modern email clients. But look below the surface and you’ll discover some very handy features.

For one, you have the option of tagging emails as they come in. Just add tags like Personal, Work, and ToDo and suddenly conversations become much easier to find later on. Even better, create your own tags to make the classification system as specific as you need it to be.

Thunderbird features an integrated calendar and chat client, both of which are indispensable for work, and boasts great privacy features — like not automatically displaying images (hence stopping pixel trackers) when you open emails (can be changed in Preferences).

Overall, Thunderbird has some powerful value propositions, but is also a bit ugly and unintuitive. So, if the looks don’t bother you, give it a try. Otherwise, you’re better off using another option.

What’s great:

  • Tagging is powerful and helps you organize your emails quickly

  • Precise search

Not so great:

  • Not the prettiest interface

  • Unintuitive user experience. It takes time to figure out Thunderbird’s best features.

Kiwi for Gmail: Best Gmail app for Mac

If you don’t use Gmail, you can skip this one: Kiwi isn’t for you.

But for all other Gmail for Mac users, Kiwi for Gmail is an excellent Mac mail option. A desktop app with the look and feel of your browser email inbox, Kiwi features the ability to combine multiple accounts and filter your inbox with Focus to organize correspondence by date, importance, attachments, and more.

In many ways, Kiwi is Gmail’s missing ingredient, making the best free email provider online also the premier Gmail app for Mac. What’s even more exciting is that Kiwi lets you run G Suite apps like Google Docs and Sheets outside of your browser. Being able to leave Chrome or Safari behind and get some focused work done alone makes Kiwi worth the install.

What’s great:

  • Kiwi makes Gmail better
  • Combine multiple Gmail accounts
  • Focused work outside the browser with Google Docs

Not so great:

  • Doesn’t support non-Gmail accounts

Spark: Best Mac email client for a clean inbox

A relatively new email client for Mac, Spark is based on an intriguing premise: What if your inbox was able to sort itself out based on your priorities but without your input?

Spark’s Smart Inbox algorithms are able to instantly identify whether an email is personal, work-related, or just a newsletter you signed up for years ago because it gave you a coupon but have since completely forgotten about. This kind of artificial intelligence works so well that Apple gave Spark an Editor’s Choice Award a few years ago.

In its quest for widespread adoption, Spark doubles down on usability, offering quick, one-click replies with generated text based on how you typically respond to emails and powerful automatic functions to clean up your inbox in seconds. Besides, the app is beautifully designed and very easy to use.

Of course, for Spark to have all of these powerful features, complete access to the content of your emails is required — which might raise some privacy-minded eyebrows. However, a lot of people would be happy to offer that in return for ease of use. So, if this notion doesn’t bother you, Spark might well be the best free email app for Mac.

What’s great:

  • Clean design
  • Smart Inbox organizes your unread emails
  • Could be the most professional email client for Mac

  • The only non-Apple email client with the Apple seal of approval

  • “Send later” feature lets you schedule emails

  • Frequent updates

Not so great:

Macos Best Mail App Software

  • Requires more of your data than other email clients

Canary Mail: Best security in an email client for Mac

New to the Mac email client game, Canary Mail’s outstanding list of features still makes it a worthy contender.

Canary Mail prioritizes security and privacy, providing every email you send with end-to-end encryption, so that if your data is ever intercepted it can’t be read. Even better, you don’t have to change any settings to do this — everything is set up right out of the box.


Add to that a fantastic design and some excellent filtering options, such as natural language search, smart tags, algorithmic bulk cleaner, and intelligent typography enhancements, and Canary Mail might well be the best email app for Mac, period.

What’s great:

  • Great design
  • Smart filters
  • Intelligent typography
  • Automatic end-to-end encryption
  • Available to all email providers
  • Algorithmic bulk cleaner

Unibox: Most innovative email client for Mac

The most exciting thing about Unibox is how it fundamentally changes the way you see your inbox. Instead of organizing everything by date received or subject, Unibox structures every conversation around contacts. That way your inbox resembles your text messages or messaging app, making everything intuitive and easy to navigate.

The developers of Unibox worked hard on making their email client for Mac the easiest to use on the market — and it shows. The design is stunning and you can easily respond to any email in the same window, get previews of attachments right there, and just scroll to remind yourself of all the conversations you’ve had with that person.

What’s great:

  • Email like messages
  • Intuitive and easy-to-use design
  • Works with all major email providers

Best of all, Canary Mail and Unibox are both available for a free seven-day trial through Setapp, a subscription platform with over 150 top Mac apps chosen to make your day more productive and fun. Now can’t you wait to go back to emails already?

Find that the Mail app randomly opens while you are working on your Mac running macOS Mojave?

There have been similar cases like this, with several users having reported it over on the forums. Apparently, the Mail app will just pop up into the screen while you are working on your Mac. It is indeed frustrating to have to minimize or close it from time to time, which interrupts your attention.

Now there are a couple of factors that can cause this issue, especially on the software level. It may well be an incorrect configuration in your Mac, a third-party email account conflict, or a software glitch. Whatever the cause is, there is always a fix for a particular issue. If not, a temporary workaround can be applied until a permanent fix is applied.

In this guide, we will discuss the probable causes of this together as well as share the suitable fixes associated with it. Hopefully, by the end of this guide, you will be able to fix your Mail app that opens randomly on Mojave.

Without further ado, let’s dive in!


How to Fix Mail App Opens Randomly Mojave: 10 Ways

1. Update macOS Mojave.

The first and most likely cause which your Mail app is not behaving normally is because of a bug in the macOS Mojave version itself.

To fix this issue with the Mail app, you must make sure that your macOS version is also up to date. It’s possible that by the time you read this post that Apple may have already addressed this bug and released a patch for you to install.

Here’s how you can install the latest macOS updates on your Mac if you haven’t already:

  1. Go ahead and click on the Apple menu icon, then the System Preferences option, and then click on the Software Update option.
  2. Then, click on the Update Now option to install it. If you can’t find this option, that means your software is already up to date.
  1. Finally, you can opt to click on the More info option to view details about the update. If you are an advanced user, you can choose a specific update to install and ignore the ones that are not relevant to your application.

Once you see the message that your macOS is updated, your applications such as your Mail app and other Apple core applications will also have been updated. You may test once again by carrying out your everyday tasks with your Mac and see if the Mail app opens randomly again.

2. Check your Mail Settings.

Another possibility why your Mail app is popping up randomly onto the screen is because it may have been misconfigured without you knowing it. This happens especially if we’ve made any changes to the Mac, such as recently downloading a new application or updating the macOS. We will not know for sure where the issue exactly is, but the following steps will be helpful to check and verify if the configurations for the Mail app are correct and should behave the way it was intended.

Take note there are two parts to do this: 1) Mail App Settings and 2) macOS settings. We will go over both and show which of all the settings are required and which are not.

Here’s what you need to do in your Mail app settings:

  1. Go ahead and click your Mail app, then click on the Preferences option and then General option.
  2. Then, on the Check for New Messages option, click on the choices, and set the value to Manually. You will get to see new messages if only you click on the Get Mail button.
  1. In the same setting page, uncheck the box where it says Prefer opening messages in split view when in full screen. This will prevent opening a split view window when there are any notifications from your Mail app.
  2. Now click on the Rules tab on the top section and check the email rules that are currently set up for your Mail app. If there are rules that use a script that triggers a notification, select the name of the rule on the list, and click on the (-) remove option.
  3. Finally, close your email app and relaunch it. Minimize your mail app by clicking on the yellow ( – ) button at the top right corner of your application window.

The above changes will directly affect how your Mail app behaves but does not address the macOS itself, which we will be the next part we will go through.

Here’s what you should do in your macOS settings:

  1. Go ahead and click on the Apple menu icon, then click on the System Preferences option.
  2. Then, click on the Mission Control option and uncheck the box that says Displays have separate Spaces. This will avoid triggering split display if you are previously using multiple displays.
  3. Now go back to the System Preferences page, and click on the Users & Groups option.
  4. Next, click on the Login Items option and look for your email account or any account associated with your Mail app on the list. Click on ( – ) or remove option, and this will prevent your application from opening automatically after logging in to macOS.
  1. After that, go back to the System Preferences page, and click on the Energy Saver option. Then, uncheck the Enable Power Nap checkbox to prevent checking new email messages when your macOS goes to sleep.
  1. Finally, restart your macOS Mojave by clicking on the Apple menu icon and click on the Restart option.

After your Mac successfully starts up, the Mail application should not open on its own automatically. If you wish to use the Mail application, then you may launch it and opt to minimize it so that it stays in the background. Again you should find that after completing the above steps that the Mail app will not annoyingly abrupt you during your work. If you still find that the issue persists, then keep reading.

3. Uninstall Any Third-Party Email Software.

Several users have also found this issue also occurred due to a conflict between the Mail app and third-party installed email services. This issue is similar to when you have two antivirus software installed on a machine. Since both services use the same protocol and resources, it can cause problems with your system.

Best Mail App For Macos 2020

To fix it, you will need to temporarily uninstall any third-party email software which you have installed on your Mac and then retry using the Mail app.

Here’s how you can do it:

  1. Go ahead and click on the Finder icon in the Dock section of your macOS Mojave and click on Applications in the Finder sidebar.
  2. Then, find and double-click the Uninstall (App) or (App) Uninstaller on the 3rd party email software folder for the uninstall process.
  3. Now, if the application does not have the uninstaller program, drag the 3rd party email software folder or icon to the Trash at the end of the Dock section.
  4. Finally, repeat the steps above if you have more 3rd party email software installed in your macOS Mojave.

If your application was purchased from the App Store, learn how to uninstall the app using Launchpad.

4. Disable Google Calendar Notification.

If you are using a Gmail account on your Mail app, then you might want to check your Calendar notifications setting.

Google’s Calendar app is notorious for having issues with how their notifications work. So if you use it extensively, you will want to make sure that the settings for the notifications are disabled. For instance, there is a hidden schedule notification inside your Google Calendar that has been reported by users to be the cause of this random pop-up issue on your Mail app. We will guide you on how to locate this setting as well as all the other settings that you should disable to prevent notifications from the Google Calendar to pop-up.

Here’s what you should do:

  1. Go ahead and log in to your Google Calendar page using your web browser.
  2. Then, click the gear icon on the upper-right corner of the page and then click the Settings option on the drop-down menu.
  1. Now, click on your calendar name under Settings for my calendars section and click on the Event Notifications.
  2. Check for the email notification schedule if there’s any. If there is an email notification set up, remove it by clicking the ( X ) icon or Remove Notification option.
  1. Also, scroll down on the All-day Event Notification section and do the same procedure in Step 4.
  2. Next, on the Other notifications section, change the drop-down choices from “Email” to “None” value to remove email notifications.
  1. Finally, close your Mail app and relaunch it.

Having disabled all of the hidden notification options in your Google Calendar, any events or actions related to the Google Calendar from your Gmail account will not be notified. This will help stop your Mail from suddenly popping-up on your screen every time there’s a hidden notification in your Gmail account.

5. Generate New App Password for Gmail.

Again this is primarily directed to users who have a Gmail account.

Gmail recommends from the moment you sign up with them that you add an extra layer of security for your email accounts. That’s a good thing! But sometimes, this additional layer of security messes up the way the Gmail account is synced with your Mail app. It may notify you unconventionally that your application is not safe because the application identifies it as a third-party email address account. Hence, it does not have a proper notification protocol to notify the user with contrary to what Apple provides it.

One safe and secure way to go about this is to generate a new password for it via your Mail app.

Here’s how you can do it:

  1. Go ahead and click Mail option on your Mail app on your macOS Mojave.
  2. Then, click the Preferences option and then click the Accounts option.
  3. Now, select your Gmail account and then click on ( – ) icon or also known as the Remove option.
  1. After that, close your Mail app and relaunch it.
  2. Go back to the Mail option, then click on Preferences, and then Accounts option.
  3. Next, click on the ( + ) icon or also known as the Add Account option, choose the “Other Mail Account…” option instead, and enter your full Gmail email account address.
  1. Then, launch your web browser and sign in to your Google Accounts page.
  2. Click on the Security option on the left side and go to the Signing in to Google section. Generate an application password for your Mail app using the App Password option and follow the instructions.
  3. Finally, go back to your Mail app and use the app password that is newly generated to sign in your Gmail account on your Mail app.

Now that your Gmail account has a new app password for your Mail app, it should not notify you that you need to secure your account. If the issue persists, keep reading as we’ve got five more methods for you to try out.

6. Remove Email Account from Mail App and Forward All Emails.

This is an alternative solution in case none of the solutions above work for you.

For instance, if you are having a hard time setting up your Gmail account, then you can opt to remove it from your Mail app if it continuously causes you trouble. You can refer to the Steps 1 to 4 of the previous method on how to remove your Gmail account from your Mail app.

⚠️ Note

This method can also be applied with other email services such as Microsoft Outlook, Yahoo, and Zoho. Please refer to the links attached for the respective guides on how to set it up for those services.

If you do proceed with removing your Gmail account from your Mail app, then the following workaround can help set up a forward filter on all of your emails on your Gmail account to your primary email account. This ensures that you are kept notified with the emails but without having the actual account on your device.

Here’s how you can do it according to Google Support:

  1. Go ahead and log in to your Gmail account using a web browser.
  2. Then, click on the gear icon or Settings at the top-right portion of the page.
  3. Now, click Settings on the drop-down menu and click on the Forwarding and POP/IMAP option.
  4. Scroll down to the Forwarding section and click the Add a forwarding address option. The forwarded address can be your main email address or an email address where you prefer your emails to be forwarded to.
  1. Enter your primary email address to the space provided and click on Next, then Proceed, and then the OK option.
  2. Check your primary email address and check for a verification message. Click the verification link in that message.
  3. Next, go back to the page where your Gmail setting is and refresh the page.
  4. Again, click the Forwarding and POP/IMAP option and scroll down to the Forwarding section. Choose Forward a copy of incoming email to option and choose to keep Gmail’s copy in the inbox.
  5. Finally, scroll down at the bottom of the page and click Save Changes.

With the forwarded setup shown above, you can have your Gmail messages appear in your primary email account on your Mail app, which should stop the conflicts. Again, this is a workaround to the other methods, so it is up to you whether you want to go through with this solution.

7. Force Quit Mail App.

If you haven’t already force quit your Mail app on your Mac, then it’s certainly worth doing so. By force quitting your Mail application, you’re inherently terminating its process, which will allow you to jumpstart it.

Doing this doesn’t mean your email account will miss out on any new emails since we’re just restarting the Mail app itself and not your email account. It’s a useful trick which we’ve found to be extremely effective from our previous guide on tackling the various issues with the Mail app on macOS Catalina.

To do this, you will need to press and hold the Option, Command, and Esc (escape) keys simultaneously on your keyboard to open the Force Quit window.

Under the Force Quit Application section, a list of applications that are launched will be provided. Search and click the Mail app on the list and click on the Force Quit button at the bottom.

This will terminate the Mail application, and you will not be bothered by it until you relaunch the Mail app. Try it and see if it works. Let us know down below whether this method works for you.

8. Prevent Applications from Re-Opening.

It is also possible that you have previously opened the Mail application before the shutdown or sleep process. There is a feature on your Mac that allows you to resume the applications you are working on after you restart or resume from a sleep process. So your Mail will still be running in the background and might be able to disturb you when you are working on your computer.

To fix this, you need to deselect” Reopen windows when logging back in” option when prompted before the restart process. This will prevent all applications to open automatically after you log back into your Mac. With this, you get to choose to open the applications you only need at the moment.

Another way to close applications and prevent them from reopening is in your Mac’s settings. To locate these settings, click on the Apple menu icon, then click on System Preferences. Next, click on the General option. Now scroll down and check the box that says “Close window when quitting an app” option. Selecting this option will proceed to close the Mail app window as soon as you’re done using the Mail app.

9. Restart Device in Safe Mode.

Restarting your Mac is a standard de-facto solution for most issues experienced. It is an effective solution that is recommended by Apple themselves, especially if there are errors encountered in the operating system (OS) level.

It’s a relatively quick method and does not result in any of your data or information being erased. You can verify this by going onto Apple’s documentation for carrying out Safe Mode for Mac machines.

Here’s how you can do it:

  1. Go ahead and restart your macOS Mojave by clicking on the Apple menu icon, and then click on the Restart option.
  1. Then immediately press and hold the Shift key on your keyboard until the Apple logo appears. If you don’t see the Apple logo, learn what to do.
  2. Next, release the Shift key when the login window appears. If your startup disk is encrypted, learn more about what to do.
  3. Finally, when your macOS has fully loaded, restart your computer by clicking on the Apple menu icon and click on the Restart option. Do not press any keys to startup normally.

By doing this process, here are the things that it does to your Mac:

  • Safe mode verifies your startup disk and attempts to repair directory issues if needed.
  • It loads only required or core kernel extensions.
  • The process prevents startup items and login items from opening automatically that may have conflicts with your other applications.
  • It also disables user-installed fonts and other customized settings.
  • Finally, it deletes font caches, kernel cache, and other system cache files

If the Mail app issue persists even after you the process, you will also want to check if your Mac may have incompatible login items. But most of the time, by carrying out the Safe Mode restart, the issue will get resolved as your system cache will have been rebuilt and updated.

10. Contact Apple Support.

If none of the solutions in this guide work for you or if you find solutions such as restarting using the Safe Mode a little too complicated, then we always recommend that you bring in your Mac to your nearest Apple Store. They can cover pretty much anything with regards to Apple products, especially software and hardware repair.

Moreover, if you have done everything you can from this guide and think that this is a bug with macOS Mojave itself, then we ask that you write a feedback to Apple. This way, you will be helping them collect the data they need to fast track the bug fix process. Be sure to mention what version of Mail app and macOS Mojave you are using. The more of us who report, the sooner we can get a patch for it. 🙂
