Hide Email Button on Recipient's Page

I have added an email button to my document but the email button is visible on the emailed page. Is there a way to hide the email button on the emailed page? My email button script is as follows:

var newDoc = this.extractPages(0); // extract page 1

newDoc.mailDoc({cTo: ""}); // mail the new document

newDoc.closeDoc(true); // close the new document

Thank you
