This wikiHow teaches you how to restore an email message that was mistakenly placed in the Junk folder in the iOS Mail app. You can also use this method to prevent similar messages from entering the Junk folder in the future.
Step

Step 1. Launch Mail on your iPad or iPhone
The icon is blue with a white envelope in the center. This app is usually located on the home screen.

Step 2. Touch the arrow pointing to the left in the top left corner
The Mailboxes menu will open.

Step 3. Touch Junk
The icon is a trash box with an "X" in the middle.

Step 4. Touch the message you want to recover
At the bottom of the screen will appear several icons.

Step 5. Touch the folder-shaped icon
This icon is second from the left at the bottom of the screen. Doing so will display a list of folders.

Step 6. Touch Inbox
The message you selected will be moved to the Inbox. Emails similar to the ones you choose in the future will go directly to the Inbox instead of the Junk folder.
