This kind of data is NOT allowed to be used:

Purchased e-mail addresses
Purchased data is strictly prohibited in our system! You have not obtained the express consent of the recipients for the sending of e-mails.
E-mail addresses copied from the internet
E-mail addresses stated as a means of contact on websites or in public directories are not permitted.
Single opt-in
E-mail addresses collected via a form using the single opt-in method without confirmation are not permitted. This data may not be used because anyone can, in this way, enter someone else's data against their will. The secure double opt-in method must be used for registration using a form.
B2B addresses: sending without permission
Ein weit verbreiteter Irrtum ist die Annahme, dass im B2B-Umfeld für die Zusendung von E-Mails kein Werbeeinverständnis erforderlich sein muss. Tatsächlich besagt die Rechtsprechung, dass auch E-Mails an Gewerbetreibende der vorherigen Zustimmung bedarf.
Third party data
Data collected by a third party is not permitted. When collecting the data the third party obtained the consent to contact these individuals by e-mail - but you have not! If, however, this third party has collected the data in your name, you alone - and not the third party - are permitted to use this data in your own name for the sending of e-mails.
Contractual membership
Contractual membership of an association or cooperative society does NOT entitle you to simply contact other members by e-mail. Here, too, you need the express consent of the individual recipients.
Social or business networks
E-mail addresses of individuals who have shared their data with you via social or business networks such as LinkedIn, Xing, Facebook etc. may not be used. These individuals may also only be contacted via the network in question. The sharing of data does not amount to valid consent for e-mails to be sent via external systems such as ours.

You can use this data

Double opt-in via own website
All recipients have registered via their own website using a secure double opt-in procedure. To prove the registration a registration date is available.
Purchase a product or service
The recipients have acquired a product or service and were notified about the collection of data with the following sentence: "The use of your data by us to advertise similar goods and services is not excluded. You can reject this use at any time without incurring costs for this rejection other than the transfer costs according to the basic price plan." A reference in your General Terms and Conditions is NOT allowed.
Registration by offline form
The recipients have filled out a form offline and explicitly agreed to the sending of e-mails. The form must be available as evidence.
Co-registration
The recipients have registered via a competition. You were clearly and distinctly mentioned as the sponsor of this competition, stating your address, and the participants were notified that e-mails would be sent. No more than 10 sponsors are allowed to take part in competitions of this kind.
Contact by business card
Recipients who have given you a business card, for example, and want e-mails to be sent. In this case you require the business card and a written declaration of consent as evidence.
