Use Mail full screen on Mac
When you use Mail full screen, it’s easy to read and write messages and access your Inbox at the same time—perfect for copying and pasting text or attachments between messages.
Note: When Mail is full screen, messages open in Split View by default. If you want messages to slide up from the bottom of the screen instead, choose Mail > Settings, click General, then deselect “Prefer opening messages in split view when in full screen.”
