I am subscribed to Magix news because I like to get info & updates .However recently I have been bombarded by almost daily offers to buy the latest release. If this continues I will unsubscribe. Please stop this Spam email.
If you are referring to the "MAGIX Newsletter", "You can unsubscribe from the newsletter at any time. To do so just click the link at the end of the newsletter." It opens a new window to "Unsubscribe Now".
It's in small print in "General" section and hard to notice but it's there. See if it works for you.
