Add a dot-walked field Caller.Email (or User.Email or whatever your user reference in the custom table is called) to the form layout beneath the user reference. When you select a user in your reference field, the dot-walked field will automatically display the value of the Email field from the selected user record. Also make sure to configure a UI policy that would make the dot-walked field read-only because changing its value on the form would actually update the email in the referenced user record, which may not be obvious to the users.
