I just wanted to post a little something saying how much I've loved Listmail.
I'm one of your early customers, the guys you wish you didn't lock into unlimited support for life for so cheap :p, but I'm definitely VERY satisfied and I've sent a lot of customers your way over the years.
I'm not a crazy large website or power user, but Listmail has done all I've ever wanted from it. I hardly come here because it's so rock solid. I'm not even sure what version I'm running and if it's the latest, but it's been so solid and done what I wanted I haven't cared.
If anyone reading this is sitting on the fence about purchase, go ahead, you will not regret it.
All the best,
