Privacy Policy for Newsletter Subscribers


With the following information we inform you about the contents of our newsletter as well as the registration, dispatch and statistical evaluation procedure and your rights of objection. By subscribing to our newsletter you agree to the receipt and the described procedures.

Contents of the Newsletter

We will only send newsletters, e-mails and other electronic notifications containing advertising information (hereinafter “newsletters”) with the consent of the recipients or a legal permission. If the contents of a newsletter are specifically described within the scope of a registration, they are decisive for the consent of the users.

In addition, our newsletters contain information about new products, technological developments, press releases from users and manufacturers, and other specialist information from the field of bulk solids technology.

Double-Opt-In and Logging

The registration for our newsletter takes place in a so-called double opt-in procedure. This means that after registration you will receive an e-mail asking you to confirm your registration. This confirmation is necessary so that no one can log in with other e-mail addresses.

Subscriptions to the newsletter are logged in order to be able to prove the registration process in accordance with legal requirements. This includes the storage of the login and confirmation time, as well as the IP address. Also the changes of your data stored with ActiveCampaign are logged.

Use of the “ActiveCampaign” Shipping Service

The newsletter is sent via “ActiveCampaign”, a newsletter distribution platform of the US provider ActiveCampaign, LLC, 222 S Riverside Plz, Unit 810, Chicago, IL 60606, USA.

The e-mail addresses of our newsletter recipients, as well as their further data described in the context of these notes, are stored on the servers of ActiveCampaign in the USA. ActiveCampaign uses this information to send and evaluate newsletters on our behalf. Furthermore ActiveCampaign can use this data according to its own information to optimize or improve its own services, e.g. for the technical optimization of the dispatch and the representation of the newsletters or for economic purposes, in order to determine from which countries the recipients come. ActiveCampaign does not use the data of our newsletter recipients to write them down or pass them on to third parties.

We trust in the reliability and IT and data security of ActiveCampaign. ActiveCampaign is certified under the US-EU Privacy Shield Agreement and is committed to comply with EU data protection regulations. Furthermore, we have concluded a data processing agreement with ActiveCampaign. This is a contract in which ActiveCampaign undertakes to protect the data of our users, to process them on our behalf in accordance with their data protection regulations and in particular not to pass them on to third parties. You can view ActiveCampaign’s privacy policy at

Registration Details

To subscribe to the newsletter, simply enter your e-mail address.

Optionally, we ask you to enter your first and last name. This information is only used to personalise the newsletter. Furthermore, we also ask you to optionally indicate your date of birth, gender and industry. We only use this information to adapt the contents of the newsletter to the interests of our readers.

Statistical Surveys and Analyses

The newsletters contain a so-called “web-beacon”, i.e. a pixel-sized file which is retrieved from the ActiveCampaign server when the newsletter is opened. Within the scope of this retrieval, technical information, such as information about the browser and your system, as well as your IP address and time of retrieval are initially collected. 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 ActiveCampaign, 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.

Online Access and Data Management

There are cases where we direct the newsletter recipients to the ActiveCampaign website. For example, our newsletters contain a link with which the newsletter recipients can call up the newsletters online (e.g. in case of display problems in the e-mail program). Furthermore, newsletter recipients can subsequently correct their data, e.g. the e-mail address. Likewise, ActiveCampaign’s privacy policy is only available on their site.

In this connection we pointed out that on the websites of ActiveCampaign cookies are used and thus personal data are processed by ActiveCampaign, its partners and service providers (e.g. Google Analytics). We have no influence on this data collection. For more information, please refer to ActiveCampaign’s privacy policy. In addition, we would like to draw your attention to the possibilities of objecting to the collection of data for advertising purposes on the websites and (for the European area).


You can cancel the receipt of our newsletter at any time, i.e. revoke your consent. At the same time, your consent to its dispatch via ActiveCampaign and the statistical analyses expire. A separate cancellation of the dispatch via ActiveCampaign or the statistical evaluation is unfortunately not possible.

You will find a link to cancel the newsletter at the end of each newsletter.

Legal Basis General Data Protection Regulation

In accordance with the provisions of the EU General Data Protection Regulation (GDPR) valid from 25 May 2018, we inform you that your consents to the sending of e-mail addresses are based on Art. 6 para. 1 lit. a), 7 GDPR and § 7 para. 2 no. 3 and para. 3 UWG. The use of the shipping service provider ActiveCampaign, performance of statistical surveys and analyses as well as logging of the registration procedure, are carried out on the basis of our legitimate interests pursuant to Art. 6 para. 1 lit. f) GDPR.
