I would like to use a service that will send my marketing email to targeted, opt-in addresses, so I can offer them my free service. It must be truly opt-in, market interested - no spam addresses. I have looked at the offer from www.inetgiant.com , but I'm not sure if they're good and there's not much detail on their site. Has anyone used them? Who would you guys recommend for a service that can provide targeted, opt-in lists and do the mailing for me? Thx.
