About App Marketplace Pardot install

As it turns out, it is not necessary to match the email addresses of the Zoom account and the Pardot user account. (This may be a different story if Zoom and Salesforce are directly linked, but in this case, Zoom and Pardot are linked.)
When setting up a connection between Zoom and Pardot, Pardot user information is of course required for authentication, but since the user and Zoom account are not connected by email address, you should not have to worry about this.
