Is there a way to know when new email arrived using mu4e-index-updated-hook?

Is there a way to know when new email arrived using mu4e-index-updated-hook?

[Hugo M]

I have this:

(defun ham-email-arrived-notif ()
  (notifications-notify
    :title "Emails actualizados, m'hijo"
    :body "Quizás tengas un email"
 ;;   :app-icon "~/.emacs.d/icons/mail.png"
    :urgency 'low)  
)
(add-hook 'mu4e-index-updated-hook #'ham-email-arrived-notif)

But it always alerts me when index is updated, even if I have no new email (yes, I noticed the hook's name).

Is there a way to check if there's any unread email in the mu4e index? (or to ask mu4e to retrieve all emails with "unread" flag) 

Thanks!

If you're using maildir formats. You can find some solution with Google.
Because maildir use structure Mailbox/{new,cur,tmp}. All new emails are in
Mailbox/new/. So you can detect them with some function.
