How can I organize my mailboxes in Google mail?

Click in the square to the left of the email

Options appear at the top of the email

From here, you can choose to

Archive

Report as Spam

Delete

Mark as Unread

Move it to a label

Add it to several labels

Choose an option from the 3 vertical dots

       Mark as unread

       Mark as important

       Add to Tasks

       Add STAR

       Filter messages like these

       Mute

Remember: the All Mail label will always house a copy of all mail, no matter what labels have been applied to the emails.
