Is it possible to create an email subscription service in SharePoint 2010? We have an ASP.NET app where users sign up to receive a bi-weekly newsletter. Our SharePoint installation is currently internal only, but we wondered if we could perhaps have one section that's external for this purpose.
Users would sign up and receive an email with a confirmation link; once clicked, they'd be confirmed on the database as having a valid email address. Admin users would create the newsletter in SharePoint and send it to the list of subscribers.
Any thoughts on this? Also, can a SharePoint site have an internal and external parts? Any 3rd party modules you can recommend? Thank you.
