• Please look for emails sent from registrierung@dinmedia.de.
  • Check your spam folder.
  • Check whether your company uses a central spam filter that only allows emails through if you confirm them (you may see the error message “rejected by our SPAM blocker). It is not technically possible for our database to communicate directly with spam filters. Please ask your administrator to always allow emails from registrierung@dinmedia.de.

If this does not help, please contact us.
