Subscription email OFF?

Hello, Our non-profit organization is using Smartlist to manage its mailing lists for press contacts, donors, etc.. We have a web interface that lets the individual managers add/remove people from their mailing lists, but I was wondering if there was a way to turn the "you have been subscribed to so&so list" off. Instead of using outlook to manage sending emails out, I set up smartlist mailing lists for obvious reasons. They are complaining to me now that they do not want the recipient receiving an email if they are added to the list. Any help would be much appreciated -Hitesh Aidasani Asian Americans for Equality hitesh@aafe.org
