Braille Formats §2.3.6(c) states that: "The publisher's URL is included on the title page if it appears on the title page, copyright page, or cover of the book. The website is inserted on the line after the publisher's city/state."
After polling others on the Formats committee: Formats requires the website, not the email address. We are agreed that the email address would not take the place of the website. So no, do not include the email address as noted above.
