bulk email

We're looking for (2) additional bulk email sending servers for long term highly targeted email campaigns for USA mainstream business to business mailings. We are 100% compliant with USA can-spam laws and must maintain that. No proxy mailing. Legit IPs, Legit sending domains (we supply) with correct rDNS. Our mailings are not 100% opt-in, but generate few complaints. We mail slow and steady, we supply the lists. We want to setup with reliable hosting anywhere in the world with good connectivity and good price. (Currently we have servers in China which has been OK) Experience with bulk email server admin required. We will handle our mailings by remote access. This is a long-term arrangement. Thanks.
