Mailing list management?

[Daniel DiGiacomo]

Hello fellow wholesalers... I'm currently using Mailchimp to manage my mailing lists. What do you use? And have you tired other services? Pros, cons?

I don't like the double opt-in requirement at Mailchimp, seems like my "confirmation" e-mail often goes into the subscribers spam and I never capture them. I want something a bit simpler.
