def receive_email(self, email):
self.emails.append(email)

    def __init__(self, sender, receiver, subject, body):
        self.sender = sender
        self.receiver = receiver

        self.timestamp = datetime.datetime.now()
        self.read = False

    def mark_as_read(self):
        self.read = True

    def display_full_email(self):

I don’t think you need an f-string here. Just pass the values directly to the send_email parameters and use ramy and tory as normal variables.

The send_email method expects the receiver to be a User object, not a string. Using f'{ramy}' converts the ramy object into a string, which will break the system when it tries to access receiver.name.

:joy: just removed the f string and it worked
