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:

Go ahead and click on the Apple menu icon, then the System Preferences option, and then click on the Software Update option.
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.

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:

Go ahead and click your Mail app, then click on the Preferences option and then General option.
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.

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.
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.
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.
