Good to know... A while ago i opened a free account to test the unseen.is 'Private and Secure" mail service. I am glad i did not pay for it, or use it for real mail, because a week later, i received an unseen.is news or update mail from: verticalresponse.com and or vresp.com. So i visited verticalresponse.com with Firefox with Ghostery , with an overflow of trackers, and it became clear that both my unseen.is and the other test emailaccount i used to open the unseen.is account were handed over to this marketing company to send me marketing mail. Even more shocking was the fact that the mail account i especially created to open the unseen.is account, received a marketing mail about neomailbox.com a compatitor from unseen.is and a business relation? from the E-mail marketing company. A very strange thing that unseen.is is providing a E-mail marketing company their customers emailaddresses. I asked unseen.is why , but ... no response yet. Good to know i think ...
