Privacy Policy- your reliable barrier against unwanted mails
Because most of the tests take place, before the E-Mail is getting transmitted, theres also no danger, that your E-Mail is getting read by us. At 11000 E-Mails per Second that would be impossible!

In your protocol, you’ll find therefore only the following identification data:

• Sender of the Mail
• Receiver of the Mail
• IP-Address of the sender
