Junk emails populating flagged folder

Hi Abetome,

Thank you for using the Apple Support Communities! The steps below can help organize mailboxes including junk mail:

Organize email in mailboxes on iPhone

Move or mark multiple emails

1. While viewing a list of emails, tap Edit.

2. Select the emails you want to move or mark by tapping their checkboxes.

3. Tip: To select multiple emails quickly, swipe down through the checkboxes.

4. Tap Mark, Move, or Trash at the bottom of the screen.

View emails from one account at a time

If you use multiple email accounts with the Mail app, you can use the mailboxes list to view emails from one account at a time.

Tap  in the upper-left corner, then tap a mailbox below the email account you want to access.

Each mailbox listed below a particular email account only displays emails from that email account. For example, to view only emails sent from your iCloud account, tap iCloud, then tap Sent.

Move an email to junk

To move an email to the Junk folder, open it, tap , then tap Move to Junk.

Hope this helps!

Have a great day.
