7. Newsletter

If you, in accordance with Art. 6 para. 1 sent. 1 lit. a DSGVO/GDPR, have expressly consented, we will use your email address to send you regular newsletters. For the receipt of the newsletter the indication of an email address is sufficient.

Credentials: To subscribe to the newsletter, it is sufficient to provide your e-mail address. Optionally, we ask you to give a name in the newsletter for personal address.

Logout: Opt-out, ie. revocation of your consent, is possible at any time, for example via a link at the end of each newsletter. Alternatively, you are welcome to send your unsubscribe request to by e-mail at any time.

Double opt-in and logging: Registration for our newsletter is done in a so-called double-opt-in procedure.

8. Newsletter service provider

Our newsletter is sent by our e-mail service provider (Inxmail GmbH, Wentzingerstr. 17, D-79106 Freiburg / GERMANY), whose data protection regulations can be viewed under the following link. The use of the e-mail service provider is based on our legitimate interest acc. Art. 6 para. 1 lit. f DSGVO/GDPR and a order data processing agreement acc. Art. 28 para 3 sentence 1 DSGVO/GDPR. The newsletter service provider may use the data of the recipient in a pseudonymised form to optimize or improve their own services. However, the e-mail service provider does not use the data of our newsletter recipients to address them themselves or to pass the data on to third parties.


9. Newsletter – measurement of success

The newsletters contain a so-called web beacon or tracking pixel, i.e. a pixel-sized file that is retrieved from our server (or from the one of our shipping service provider) when the newsletter is opened. For the evaluations, we link the data collected automatically when you visit the website (see “Collection of log data” above) and the web beacons with your e-mail address and an individual ID. This information is used to technically improve the services based on the technical data or the target groups and their reading behaviour based on their retrieval locations (which can be determined using the IP address) or access times. The statistical surveys also include determining whether the newsletters are opened, when they are opened and which links are clicked. For technical reasons, this information can be assigned to the individual newsletter recipients. However, it is not our intention, nor that of the shipping service provider, to observe individual users. The evaluations serve us much more to recognize the reading habits of our users and to adapt our contents to them or to send different contents according to the interests of our users.

DSGVO/DGPR). The prerequisite for this is the transmission of the IP address in order to be able to send the respective contents to the browser. Third-party providers may also use so-called pixel tags (invisible graphics, also known as “web beacons”) for statistical or marketing purposes. Pixel tags” can be used to evaluate information such as visitor traffic on the pages of this website.
