Use of e-mail address for direct advertising purposes

We intend to use electronic postal addresses (e-mail-address) obtained during purchase order processes or on rendering services pursuant to the provisions set forth in § 7 subparagraph 3 German Unfair Competition Act (UWG, please see excerpt of the text below) for direct advertising purposes with respect to our own similar goods or services. You may object to the use at any time in case you do not consent to this. Please find contact details for such objection in our Legal Notice.

Purchasing and security

We attach particular importance to the protection of our customer data. This is why we exclusively use tested encryption technologies in communicating. The SSL (Secure Sockets Layer) network protocol guarantees safe data traffic between siewert-kau.de and our customers. SSL was specifically developed for safe data transfer on the internet. The URL will change in case SSL encryption is being used during data traffic. In this case of encrypted data transfer it will read “https” instead of “http”.

Extract from the German Unfair Competition Act (UWG)

Section 7 – Unconscionable pestering

  1. A commercial practice unconscionably pestering a market participant shall be illegal. This shall apply to advertising particularly in cases where it is apparent that the solicited market participant does not want this advertising.
  2. Unconscionable pestering shall always be assumed in the case of
    1. advertising using a medium of commercial communication not listed under numbers 2 and 3 which is suited to distance marketing and through which a consumer is persistently solicited although it appears that he does not want this;
    2. advertising by means of a telephone call, made to a consumer without his prior express consent, or made to another market participant without at least the latter’s presumed consent,
    3. advertising using an automated calling machine, a fax machine or electronic mail without the addressee’s prior express consent, or
    4. advertising using a communication where the identity of the sender, on whose behalf the communication is transmitted, is concealed or kept secret, or where there is no valid address to which the recipient can send an instruction to terminate transmission of communications of this kind, without costs arising by virtue thereof, other than transmission costs pursuant to the basic rates.
  3. Notwithstanding subsection (2), number 3, unconscionable pestering shall not be assumed to exist in the case of advertising using electronic mail if
    1. the entrepreneur has obtained from the customer the latter’s electronic mail address in connection with the sale of goods or services,
    2. the entrepreneur uses the address for direct advertising of his own similar goods or services,
    3. the customer has not objected to this use; and
    4. the customer has been clearly and unequivocally advised, when the address is recorded and each time it is used, that he can object to such use at any time, without costs arising by virtue thereof, other than transmission costs pursuant to the basic rates.
