With a new macOS out there, some Mac users have encountered Mac Mail problems following an attempt to update to macOS Catalina.
If you are experiencing any of the problems listed below, we’ve got fixes to get your Mac Mail working as it should. Despite numerous improvements from the previous operating system, there weren't too many changes made to the Mail App in Catalina.
However, there have, and were numerous reports of the app crashing or unexpectedly quitting, which is why fixes and workarounds are currently needed to ensure the Mail app works as it should.
Here are a number of problems and 12 fixes for those who've encountered unexpected issues with Mac Mail.

Apple Mail will not delete an email. Apple Mail is unable to move the message to the Trash mailbox. This is a known bug with Apple Mail. Disable Move deleted messages to the Trash mailbox. Open Preferences. Select Accounts. Select your Account and click Mailbox Behaviors. Untick Move deleted messages to the Trash. This week, an updated Apple support article offers a reminder on what to do if Mac OS X Mail keeps crashing (“unexpectedly quitting” in Apple-speak). The most likely cause is a “damaged”.
This is one of the most common problems people keep encountering, and it seems the fix is pretty simple too.
If Mail launches that way, drag the icon out of the Dock. Once that has vanished, drag the icon — a copy of it will be made —back into the Dock. Then close Mail and attempt to open it again via the Dock. Providing that works, your problem is fixed.
Tip: Control + Click the Mail app icon to reveal 'Open' command in the context menu.
Now, if the above solution doesn't work and Mail is either crashing or running slowly, there are other ways you can get it working smoothly again. No one can be without access to email for too long!
Do this the usual way, and if that doesn't work, move onto the next step.
If the solutions above don't work, let’s start to clear out some prior-state files on your Mac.
This requires going into your hidden Library folders.
Important: Back up the mentioned folder so you can put it back if something goes wrong.
If that has worked, you can restart Mail and it should be running smoothly. If not, there are other solutions below, and some that don't involve quite so much digging within Library folders and files - which aren't always so easy to find for those who aren't Mac power users.
In some cases, these problems have caused Mail folders to go missing - without those the app won’t work, so there are solutions to these that most users can manage without too much difficulty to get the Mail app working again.
Sometimes your Mail is slow because it has to deal with tons of open windows buried beneath other apps.
Specifically for this your email client has a lesser-known command called 'Merge All Windows'.
Click on Mail > Window
Now, choose 'Merge All Windows'
Close the redundant windows to minimize the impact on your Mail's memory. Hopefully, it will get snappier.
As outlined above, there are a number of fixes for Mail not working. Some of them require a certain amount of technical confidence and know-how. It is also worth noting that deleting the wrong folder or file within Library could disable another app accidentally. But, luckily, there's a software that can do all the fixing for you.
CleanMyMac X is a Mac maintenance app that is notarized by Apple. It's developed by MacPaw, the makers of various productivity tools for Mac. The latest version of CleanMyMac has tools that help you troubleshoot Mail, beyond other things.
Now, if you click Scan, the app will search for unnecessary files in Mail it can delete.
Now open Mail again — it should be working as good as new.
One of the quick fixes that works in 99% of the cases is to “reset” the Mail App. I use CleanMyMac X for this operation. It doesn’t delete the program itself but brings it back to its default state. This operation solves many app conflicts and incompatibilities. Also, your user files stay safe and are not being affected.
To enable this feature you need to do one preliminary step: open CleanMyMac X Preferences.
Have you installed CleanMyMac X? Ok, let's go.
Click CleanMyMac X (in the upper menu) > Preferences.
Click on Ignore List and choose Uninstaller.
Uncheck 'Ignore system applications' box.
We've just allowed CleanMyMac X to reset your Mail app.
The reset procedure:
As we mentioned above, CleanMyMac X is a really useful Mac performance improvement app. It comes with a whole load of features and tools that improve how a Mac runs, and can get your Mail app up and running again without stress or it taking very long. Hope you are receiving mail again — stay tuned for more Mac tips.
