Nothing but a spam house. They allow their customers to continually spam and harass people while violating their terms of service with no repercussions. I told their abuse alias to make sure one of their customers was never allowed to contact me again using their platform. Rather than make that happen they just unsubscribe you from one of the lists making sure the customer can still harass you so they can keep making money. This has to be one of the most unethical mail providers in the world.
