When you add a contact to a list they will have certain criteria attached to them. Custom fields, email address and the format of email that they wish to receive (HTML, Text or Both)

If you are trying to send to a list that you know has contacts in it and are receiving a notice saying that there are not any contacts, the most likely problem is that you have filtered by a criteria that your users are not.

The most common of this is filtering by HTML when your users are all subscribed as Text or visa versa.

Check your filtering for the send and then check what your contacts are listed as wishing to receive.
