Behind the scenes, the content that you type in a Mail compose window is HTML, that is presented to you as rich text (not RTF). Apple Mail does not allow you to edit this HTML content directly, or you could style it with CSS3 and the line-height property. However.. there is custom stationery to the rescue.

Apple Mail allows you to save custom stationery from its file menu. where you can subsequently edit the HTML source, and introduce the CSS3 property line-height:150%. If you have existing text in your email body, and click on your custom Mail stationery, it will change that text to show line-height of 1.5. I can send this from a Gmail account, and receive it in a different Gmail account, and the line-height is preserved.

You will need a programmer's editor ideally that can properly display HTML source. I suggest BBEdit, though the link below talks about using TextEdit in plain text mode for this purpose. The first step is to start with a blank compose window, and just add some boiler plate text, (e.g. sample text), and then from the File menu : Save as Stationery. When you do that, Mail will save it in an annoyingly obscure location with the following HTML content (I have added the line-height property already).

I named my custom stationery “foogas,” and when I apply it to existing compose text, it changes the content:

Why is Mac Mail not working?

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.

1. Mail not launching since macOS Catalina update

This is one of the most common problems people keep encountering, and it seems the fix is pretty simple too.

Fix: Launch the Mac Mail app from your Applications

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.

2. Mail crashing or running slow

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!

Fix 1: Force Quit the Mail app

Do this the usual way, and if that doesn't work, move onto the next step.

Fix 2: Restart Mail using the Activity Monitor

Go to Activity Monitor through Spotlight, Siri or Utilities.
Type ‘Mail’ into the search function.
Now click on the X symbol to force close.
Attempt to restart the usual way - or take it out of the Dock and put it back in (fix #1), before trying to restart the Mail app.

Fix 3: Delete saved Mail states

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.

Open Finder > Go to Folder..
Now hold the Option key and Select Library to open these folders.
Find this folder: Containers > com.apple.mail > Data > Library > Saved Application State

Within that, move this folder into Trash: com.apple.mail.savedState
Empty the Trash and try to restart Mac Mail the usual way.

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.

3. Mail folders missing

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.
