Makes sense, I saw the security assessment stuff for Gmail which I suppose I'll have to contend with as well, haha. I'll take another look into EmailEngine then. How do you charge, per connected user (and how much, generally)? Is it a monthly usage based subscription if so?
Edit, I just took a look at your FAQ and saw the price was 695 Euros a month. It is strange to not put this pricing on a prominent pricing tab I believe, rather than making me click a link in the FAQ to figure it out. Any reason why it's set up like that?
