Teamviewer emails do not provide an unsubscribe option. In fact, they purposely state the opposite:
"It is not possible to unsubscribe from this communication. For more information please visit www.teamviewer.com/en/newsletter/service-emails."
The lack of an unsubscription option is a clear violation of Canadian anti-spam law with penalties (fines) being $10,000 per incident. Additionally, the user can submit the case to a solicitor and file a civil suit for damages, punitive and compensatory.
TeamViewer: I suggest you alter your current law-violating policy. I am providing your company 30 days to institute a new up-to-date policy and now any other Canadian will have this information and likewise be able to affect your company's profit and compensation to your C-suite officers (Steil, Gaiser, et al).
