(14) Newsletter

We use the information below to inform you about the contents of our newsletter and the subscription, delivery and statistical analyses procedures and your right to unsubscribe. By subscribing to our newsletter, you agree to receive our newsletter and the procedures described.

Contents of the newsletter: we only send out newsletters, emails and other electronic notifications containing promotional information (referred to below as “Newsletter”) with the consent of the recipient or with legal permission. Insofar as the contents of a newsletter are specifically described when a user subscribes to it, they are binding with regard to the consent granted by the user. In all other cases, our newsletter contains information about our services and our company.

Double opt-in and logging: subscribing to our newsletter takes place using what is referred to as the double opt-in procedure. This means that you receive an email after subscribing asking you to confirm your subscription. Confirmation is mandatory to ensure that nobody subscribes to the newsletter in your name with an email address that is not yours. Subscription to the newsletter is logged to prove that the subscription process has taken place in line with the legal requirements. This includes storing the time at which subscription and confirmation took place, along with the IP address. Likewise, changes to data stored on your person with the mailing service provider are logged.

Subscription data: to subscribe to the newsletter, you just need to provide your email address.

Germany: the dispatch of the newsletter and its related performance measurement is based on the consent granted by the recipient in accordance with Art. 6 (1) (a) and Art. 7 GDPR in conjunction with Sec. 7 (2) (3) Unfair Competition Act (UWG) based on statutory permission pursuant to Sec. 7 (3) UWG.

The logging of the subscription process is based on our legitimate interests in accordance with Art. 6 (1) (f) GDPR. Our interest lies in operating a user-friendly and secure newsletter system which serves both our business interests and the expectations of our users and also allows us to prove that consent has been granted.

Online access and data management: cases exist where we direct newsletter recipients to the MailChimp website. For example, our newsletters contain a link which recipients can click on to access the newsletters online (for example, if they encounter problems viewing the newsletters in their email programme). Newsletter recipients can also subsequently correct their data, such as their email address. Likewise, the MailChimp privacy policy is only available on their website.

In this context, we would like to point out that cookies are used on the MailChimp website and as a result personal data is processed by MailChimp, its partners and service providers (e.g. Google Analytics). We have no influence over the collection of this data. Further information can be found in the privacy policy of MailChimp.

Cancellation/Revocation - you can cancel your subscription to our newsletter at any time, i.e. revoke your consent. A link for unsubscribing from our newsletter can be found at the end of each newsletter. An individual request for deletion can be submitted at any time, provided that the existence of previous consent is confirmed at the same time.

We use this data exclusively for dispatching the requested information and offers within the context of our newsletter marketing.

(14.1) Newsletter - Mailing Service

The newsletter is mailed by the mailing service “MailChimp", a newsletter mailing platform from the US provider Rocket Science Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA.

You can view the privacy policy from the mailing service provider here: The Rocket Science Group LLC d/b/a MailChimp is certified under the Privacy Shield Agreement and therefore provides a guarantee of compliance with the European level of data protection ( We use the mailing service provider based on our legitimate interests according to Art. 6 (1) (f) GDPR and a contract processing agreement according to Art. 28 (3) (1) GDPR.

The mailing service provider is allowed to use the recipient’s data in a pseudonymous form, i.e. without assignment to a user, to optimise or improve their own services, e.g. for technical optimisation of the mailing service, to display the newsletter or for statistical purposes. However, the mailing service provider neither uses the data from our newsletter recipients for their own mailing activities, nor do they pass the data on to third parties.

(14.2) Newsletter - Success Measurement

Our newsletter contains what is referred to as a ‘web beacon’, i.e. a pixel-sized file, that is retrieved from our server when the newsletter is opened, or insofar as we use a mailing service provider, from their server. Technical information, such as information about your browser and system and your IP address and the time of retrieval is collected in the first instance when the newsletter is opened.

This information is used to improve the technical performance of our services based on the technical data or the target groups and their reading habits, based on their retrieval locations (which can be determined using the IP address) or access times. The statistical surveys performed also include determining if the newsletters are opened, when they are opened and which links are clicked on. Although this information can be assigned to individual newsletter recipients for technical reasons, it is neither our aim nor that of the mailing service provider, insofar as one is used, to surveil individual users. These evaluations serve us much more to determine the reading habits of our users and to adapt our content to them or to send different content according to their interests.
