In the email to Recipients, the email body text states and shares the senders name and Adobe ID primary email address.

This is a privacy issue, there should be an option to hide the email address and/or have option to use alternative email (such as secondary email on the account).

Using Adobe Sign servers to send the email, it is inferenced that your personal email is not shown to this 3rd party. But I have discovered they have full visibility of your personal email in the body of the email text.

This is in breach of privacy laws, as a 3rd party is given this email without your knowledge in the settings of Adobe Esign.
