It seems if you're a larger company that has a lot of referrals no matter what you do they won't approve your list for emails.
They are slow getting back with you they have no customer service that answers the phone. Everything is done it looks to be overseas their English is very poor. I certainly won't recommend this go to AMS. We have collected all of our emails off of our sites and all of our sites have a box to check to give us the right to use it that wasn't good enough for them
