According to § 7 UWG (Act Against Unfair Practices) the transmission of fax advertisements is only allowed upon customer agreement. Furthermore you have to give the recipients the opportunity to unsubscribe themselves from basic rates (transmission without having to dial costly service numbers). Before transmission you have to check whether your fax is a matter of advertising. If so: Did the recipients agree? In order to use the fax as a low-cost and recent medium for advertising, it’s recommendable to get the agreement from as many participants of your target group as possible.
Recipients, who don`t want to receive commercial e-mails, can be registered for free on the German Fax Robinson list (www.robinsonlist.de). Reliable fax service providers are matching each broadcast with this list free of charge.
GTC matches your broadcast automatically with the German Fax Robinson List (www.robinsonlist.de) and marks the affected fax numbers in your distribution list. This enables an easy follow-up.
