In the Mail app, you can read emails, add contacts, and preview the contents of an email without opening it.
Tip: You can add Remind Me to the toolbar in the Mail app, to make it easier to access. See > Apps > Mail, then turn on Organize by Thread (below Threading).
Note: You can also change other settings here—such as Collapse Read Messages or Most Recent Message on Top.
