Laravel - Notifications - Customizing The Recipient

When sending notifications via the mail channel, the notification system will automatically look for an email property on your notifiable entity. You may customize which email address is used to deliver the notification by defining a routeNotificationForMail method on the notifiable entity:

    
    email_address;
    
            // Return email address and name...
            return [$this->email_address => $this->name];
        }
    }
