Can't get no email to show

[Raysz]

So I have this simple program that checks my email
everything is working the way it should

I would like to have it print there are no new messages
but for some reason I can't get it to work
I have tried all kinds of if not scenarios
even message count
with no luck

I would appreciate any help
on why I can't get this to work
can someone please show me what I am doing wrong

try:
    with MailBox(IMAP_SERVER).login(MAIL_USERNAME, MAIL_PASSWORD, "Inbox") as mb:
        """ checks the status of the inbox """
        stat = mb.folder.status("Inbox")
        """ shows the number of unscene emails """
        label_header1.insert(END, mb.folder.get() + f" - {stat['UNSEEN']}")
        for msg in mb.fetch(criteria="UNSEEN", limit=7, reverse=True, mark_seen=False):
            my_listbox1.insert(END, " " + msg.from_values.name)
            my_listbox1.itemconfig(END, fg="#660000")
            my_listbox2.insert(END, " " + msg.subject)
            my_listbox2.itemconfig(END, fg="#006600")
            #print(msg.subject, msg.date, msg.flags, msg.text, msg.uid)
except imap_tools.errors.MailboxLoginError:
    label_header1.insert(END, "AUTHENTICATION FAILED Invalid credentials "
                              "(Failure: check your username or password)")
