Champion Sound (description)

Champion Sound provides mailing list marketing and guest list management services specifically for bands, music promoters, and small venues. With a free account you can send up to 1,000 newsletters a month to all your fans.

Unlike most mailing list providers, Champion Sound lets you add new subscribers directly from your phone. Instead of telling people at the show and hoping they will remember to sign up later, you have it covered right there in person. You can create multiple lists and separate fans by city or whatever you want. Another neat tool is the mobile guest list manager. Make your guest list of VIPs for a show and check off people right on your phone as they arrive. They also offer web stats, so you can see how many people read and click through your newsletters.
