Part 1. Why Does Mail Keep Crashing on Mac?

There are various different reasons why the Mail application on your Mac continues to crash. This most likely starts occurring for you after you've completed the most recent minor software update to your Mac. Or you might have been experiencing this ever since you first performed a macOS system update because the program is not perfect yet and there's still some bugs to be fixed. In addition, setting the wrong system preferences, a full data storage could also lead to the Mail app not functioning well on your Mac.

Note: Back Up Your Mac with Time Machine First

Before you make any major system reset or adjustments to your Mac, be sure to use Time Machine to back up your Mac and keep the data safe. You can do this by simply connecting an external device to your Mac > open Preferences on the Time Machine menu > Select Backup Disk.

If you've backed up the data on your Mac but found some files were lost during performing the following solutions, hurry and try out AnyRecover to rescue your data!

1. Restart Your Mac

Whenever you are having an issue with any application such as your Mac mail keeps crashing, your first step should be to restart your computer. Allowing your Mac the time to reboot will also give the resources on the operating system the time to load properly.

  • Find the Apple logo on your computer and click it.

  • Then, click the Restart button.

2. Check Mac's Firewall Options

Normally, Mac's Firewall Preference is set to "Automatically allow built-in software to receive incoming connections". But it could happen that you have accidentally blocked the use of Mac Mail in the Firewall settings. To resolve this, unblock the application by:

  • Go to Apple menu > System Preferences > Security & Privacy > Firewall > Firewall Options.

  • Uncheck "Block all incoming connections".

  • If you see Mail.app is on the list, click on the icon and choose "Allow incoming connections".

  • Make sure "Automatically allow built-in software to receive incoming connections" is on.

4. Free Up Mac Mail Storage

Your Mail application crashing issues may stem from a simple problem that your Mail storage is just too full. You only need to delete some messages and attachments to solve this issue.

  • If you're able to open the Mail, then try deleting some old and unimportant emails to free up Mail storage.

  • If you cannot launch Mail on Mac, try the third method above by logging in Mac webmail using a web browser to access the mailbox. You can also go to Settings to check out if the iCloud storage is full.

5. Delete Locally-Stored Mail Attachments

Sometimes there can be one locally-stored mail file or its attachment that is causing a glitch to the whole Mail system, so you'd need to find out and delete the problematic Mac mail file.

  • Launch Mail > select Message on the menu bar.

  • Click on Remove Attachments to delete all downloaded Mail attachments that are stored on your Mac.

6. Remove and Restore Mac Mail Accounts

If you have multiple mail accounts on your Mac, there may be only one that is causing you trouble. Here's how to isolate the problematic mail account that causes your Mail malfunction on your Mac:

  • Go to Apple Menu > System Preferences > Internet Accounts.

  • Then uncheck all of the mail accounts listed.

  • Now try opening up your Mail app.

If it opens without any issues, then you know that one of your email accounts is causing the problem so you can add them back one by one to figure out exactly which one it is.

7. Rebuild Mac Mailboxes

The Mac Mail app has a feature where you can rebuild your mailbox if you are having significant issues. Successfully rebuilding your mailbox can prevent you from missing mail or receiving unreadable messages.

  • Launch the Mail application on your Mac.

  • Choose a Mailbox from the sidebar and then click Rebuild.

  • use finder's go to folder
  • Or you can type "~/Library/Mail/V7/MailData" in the pop-up search window by using the Go to Folder on Finder's menu bar.

  • Then, find all of the files listed that are titled "Envelope Index" and move them out of your Mail app to your Desktop.

  • reindex Mac Mailbox
