Legal situation for email marketing in GER, AUT & CHE

Increasingly, the legal experts of the Certified Senders Alliance (CSA) are asked at exhibitions and email marketing events, most recently at the DMX Austria 2016 in Vienna, how the legal conditions differ in Germany, Austria and Switzerland. In principle, without written consent it is not allowed to send advertising emails. Nevertheless, there are some differences which must be followed with regard to the concrete declaration of consent and existing exceptions in the single countries.

We have put together a table for you in which the legal specifics are shown clearly.

DKIM setup the easy way

To put it in a nutshell, DomainKeys Identified Mail (DKIM) enables a receiving email server to authenticate the sender of an email. The sending email server digitally signs each sent email.

imatrix corp. joins the CSA

imatrix corp. is, from April 2016, official Technology Partner of the Certified Senders Alliance.
imatrix corp. was founded in 2000 and has since then been providing advanced security products to protect Japanese network environment with a huge variety of scientific approach such as biological genetic technology, latest stochastic technology, deep learning technology, etc. from continuously-emerging threats.

The reason why imatrix corp. joined the CSA:

“Since the internet is connecting the world, a security firm located at East Asia like us have to take care of European-originating legitimate emails as well as spam.
The CSA is the only alliance to organize legitimate mailers in Europe and looks like it has been operated properly, so we decided to take part in the CSA.
After the participation, the performance of our email filter has become more accurate than ever.”
