Do I have the option to stop the Notification emails from Votigo to my participants?

No. Once your participants have accepted the Terms of Use [http://www.votigo.com/corp/terms.php] and Privacy Policy [http://www.votigo.com/corp/privacy.php] to be able to participate in Votigo powered campaigns like sweepstakes or photo contest or video contest, they are eligible to receive emails from Votigo unless they opt-out.
