Are there any other features of the Mail app on Mac that you’re struggling with? Let us know in the comments below.In a previous OS TechBlog post we introduced Obsidian as a note-taking app. Whatever layout you like the best for your inbox in Mail on Mac, you can make it happen with a few clicks. This lets you see the number of lines you choose in the Mail Preferences. Click View > Use Column Layout to uncheck it. On the other hand, if you’re fine with your previews on the bottom but don’t like the column view you see at the top, you can change that easily too.

You’ll then see your familiar preview on the right side of the mail instead of at the bottom. With Mail open, click View > Show Side Preview from the menu bar. If you’re not fond of the classic layout or would like to make slight adjustments, here are a couple of options. Note that the “show contact photo” option does not currently work if you use the column layout (described below). To Show To/CC label in the message list or Show contact photos in the message list, just click View from the menu bar and mark one or both of the options. And the options that came with that layout are gone too, but now accessible from the menu bar. If you open the settings for your Mail app on Mac ( Mail > Preferences from the menu bar) and head to the Viewing tab where the classic layout option once was, you’ll notice it’s no longer there. We’ll show you how to make these adjustments and change the layout of your inbox in the Mail app on Mac. However, you can change where you see the previews and whether or not you want to use a column layout. The classic layout has been updated and you no longer have that option within your Mail Preferences. With macOS Catalina, Apple made a change to the layout of the Mail app.
