There is a degree of hassle and expense involved in running your own email server but it gives you complete physical control over who has access to your email. If you use your ISP's service then their system administrators can see and read your messages. Similarly, if you use a SAAS supplier for a hosted email service, and if you use a Cloud provider you not only don't know who is reading your email, but don't even know where in the world it is kept.
