The tricky thing with email distribution is that you cannot simply use arbitrary email addresses. While you can distribute a QVW over email, you can only select your AD users as the recipients--if they have email addresses associated with their username (i.e. if you have Exchange), then it will email it to them. if you want to send to users with email addresses not associated to Windows usernames, you need to create a Custom DSC, define your users/emails, switch to DMS mode, and distribute to the usernames that you created (which now have emails associated with them). Custom users are stored in the Qliktech folder in an XML file. If you have 400 users, add 1 manually, analyze the file, and create an excel function that will output the users in the same format. Then paste the users into the XML file (you'll need to have services stopped for this to work).
