The mass mailing of marketing emails (spam) has been expressly forbidden in Switzerland since April 1, 2007. Marketing emails which are not related to content you have requested are considered to be sent unfairly if the sender has not received your permission (Opt-in-System) prior to sending the emails out. The exception is that if you have given your contact information when buying goods, products, or services, then advertisements for similar goods, products, or services offered by the sender are not considered to be unfair. An additional legal requirement is that the sender of the e-mail must be identified by name, and any messages received must contain easy and free ways of refusing future messages. More information can be found in the "Spam-Spammer-Spamming" leaflet which is available on the website of BAKOM, the Federal Office of Communications.

We ask you to state in your letter that you have not requested any such information from the sender of the commercial email, that you have not given your consent to receive such emails, and that you have not handed over your contact details in the course of an earlier purchase of goods or services. We draw your attention to the fact that the person named as the sender of the spam email is often not responsible for it, and that spammers often misuse infected PCs in order to send these emails. Attempts to trace these spammers are often unsuccessful for technical reasons. Swisscom (Schweiz) AG makes every effort to protect its customers from the unfair receipt of bulk advertisements, but can only block emails that are sent through its network.
