Any Bulk Email Sending Services for Adult Websites?

I own an adult website which I've had for over 4 years and have built a marketing list of 1400+ email contacts. I'm looking for a bulk email sending service that accepts adult sites. I signed up to Aweber and used their trial to send 500 emails but then they contacted me saying they are closing the account because they do not accept adult websites. Do you guys know of any email sending services that accept adult websites?
