Needed to put together an email blast for a soon-approaching performance and tried Firedrum. I found it to be very easy to use, and I loved getting a clear understanding of how many people had viewed my invitation. It's the best way to go if you're trying to build a fan base and want to keep track of what works, and what doesn't. For the self-employed, it's great to have something work right, and not take up valuable time ramping up on 'How To'.
