Delete a message
Do one of the following:
- In the message list: Throw the message off the side of the screen.
- In an open message: Tap the trash icon at the bottom of the message.
- To delete more than one message at once: See Select several messages at once.
If Delete Confirmation is on, tap Delete to confirm (learn how).
Deleting a message moves it to your deleted items folder. Depending on your email account, this folder is called Deleted Items, Deleted, Trash, or something else. If you accidentally delete a message, you can move it back to the original folder (learn how).
To delete all messages from the deleted items folder: Open the folder > Menu > Empty Trash.
