Work on Multiple Emails at Once
One really handy iPad Pro tip is that you can work on multiple emails at once in the Mail app. This lets you pause work on an email to answer an important email that just came in without losing track of what you are doing.
To do this, you'll need to be in the Mail app that Apple includes with the iPad and then you can start working on multiple messages.
You can put other emails down there and come back to them as well. It's handy, and an easy way to eep track of what email you need to send next.
