If you're new to Polymail, you'll notice we have a row of icons at the top of your drafts:

 

Here's a run down of what they mean from left to right:

 

  1. Inbox - clicking this will move an email back to your Inbox if it's in your Trash, Spam, Archive, a label, etc. 

  2. Snooze - lets you read an email at a later time

  3. Archive - moves an email to your Archive folder

  4. Trash

  5. Star - lets you star a message and also displays that message in your Starred folder in the left side bar

  6. Label - this lets you move this message thread to a label

  7. Read / Unread - lets you mark a read email as unread or vice versa

  8. Mute - clicking this will mute notifications for any new messages on the thread
