In short: No, this is the best practice used by all major newsletter campaign solutions and transactional e-mail services. This way of sending e-mails minimize the the risk e-mails being stopped by spam-filters, and is necessary for automatic management of bounces and tracking opens and clicks.
If you want the longer answer it comes here:
