I know they are working hard to make nice reviews here and there by doing it by themselves!

They are cheap, and they are CHEAP.

The support is rude, they are pretending that they are in US but when you try to call, it will not work if you are outside of US and they will ask you to pay for phone support: and it is NOT witten nowhere on their website.

They look good by the look at first but their SMTP is really weak and cheap: They can't even accept validated email lists because of the risk their cheap server can't handle.

They will terminate your account if they don't like you.
They will argue with you to win against their client to be right: unbelievable.
Emil delivery is no good.
Their price is a 'fishing' because after some time, you will realize that you will have to pay much more money that it's better you stay with Mailchimp or Campainmonitor etc

Stay away at all cost. Unless you don't mind to spend time & energy and then oneway they will terminate your account without any explanations nor notifications.
All the problems will be only on you as they don't care.

Good luck if you decided to go with this BLUE..
