Organize email in Mail on iPhone
In the Mail app , use mailboxes to manage your email.
Manage an email with a swipe
While viewing your email list you can use a simple swipe to move individual emails to the trash, mark them as read, and more.
To reveal a list of actions, slowly swipe an email to the left until you see the menu, then tap an item. To use the first action, quickly swipe all the way to the left.
Swipe right to reveal one other action.
To choose the actions you want to appear in the menus, go to Settings > Mail > Swipe Options.
