I did a search on Google for you and found some places where it looks like you can download the demo. Here are the results - I haven't tested these out myself so I can't guarantee anything.

Just as a reminder, spamming could get you into lots of online and legal trouble, so I would never do that.... However OPT-IN ezines etc. can be good, just make sure that people do choose to join, and can also leave your list at any time....
