How to reset Apple Mail: Can you delete mail application and reinstall it?

6 min read

Most people want to delete Mail app from Mac because of the storage space it occupies. You could have spotted Mail using up several gigabytes of valuable SSD storage if you’ve checked the Storage tab in About this Mac. It’s also common when people use other email clients such as Gmail, Outlook, Canary, Newton, and so on. In such a situation, they don’t need Apple Mail on their computers. So how to delete Mail application on Mac? Let’s find out. 

How to delete Mail application

When you buy a new Mac or upgrade the macOS, Apple Mail is already installed on your device. This means the app is secured by the system. As a result, you can’t uninstall it like a typical third-party app. However, there’s a way to clean up Mail’s downloaded attachments that occupy a big chunk of storage space. We’ll show you how to do that.

Good news: while you can’t completely delete and reinstall Mac Mail, you can do it on iOS. Simply touch and hold the app until you see the option to remove it.

In case you want to reinstall Apple Mail because it’s freezing and crashing, we’ll show you how to reset Mail on Mac. It’s nearly the same as deleting and reinstalling the Mail app when you start over. Keep reading.

How to reset the Mail app in a few clicks

As we’ve already mentioned, when the Apple Mail app on your Mac doesn’t work, you might want to reset the Mail app to factory settings. There are two common ways to do that. Let’s start with the easier one.

Follow these instructions to reset the Mail app on Mac if it won’t open or is crashing all the time: 

  1. Open Setapp and type “CleanMyMacX” or “uninstaller” in the search bar
  2. Find CleanMyMac X in the search results and click Install
  3. Once the app is installed, open it, click Uninstaller in the sidebar
  4. Select Mail from the list of apps and click on the arrow
  5. Then select the Mail’s supporting files, logs, etc. This will reveal the arrows with the text “Your selection” next to the Mail icon in CleanMyMac X. Select “Reset”
  6. Finally, click the Reset button.

The Mail app is now restored to its original state. Check if it works. 

In case your reason for deleting/resetting Apple Mail is to free up the space, use CleanMyMac X’s Mail Attachments module. Here are the steps to follow: 

  1. Open CleanMyMac X – you can install it from Setapp
  2. Click Mail Attachments from the left sidebar and click the Scan button
  3. Wait for the Scan to finish, then review which mailboxes to clean, and confirm by clicking Clean. This will erase local copies of downloaded attachments from emails, freeing up valuable space.

Remove local copies of your email downloads and attachments.

On top of that, we recommend using CleanMyMac X’s Smart Scan option to clean your system for better performance and more free storage space.

The capability of Canary Mail to encrypt emails is one of its most remarkable features.
