we decided to move to a new web hosting provider, when our former provider made big troubles and this website wasn’t available for several days.
Today our site and services are available under the .ch domain only. The .de domain is still waiting for activation.
Regarding BulkMailer users and PIN validation:
All former versions try to reach the .de domain, and so the PIN validation fails. When you are a user of the latest version 7.x (BulkMailer 2012) you can update for free to the latest release that was published today (7.7.6). Simply install the current demo version. We would kindly ask users of older versions to be patient a little bit longer, we’ll do our best to find a solution as soon as possible.
This was a move in a hurry, please excuse when not everything works as usual by now.
Thank you very much for your understanding,
