Protection from spam

What is spam?

Spam or junk is the name given to unsolicited e-mail often from untrustworthy sources. As the provider of Bluewin.ch, Swisscom has a legal obligation, pursuant to the Swiss law on telecommunications (Art 83 FDV), to protect its customers from unsolicited mass advertising to the extent permitted by the latest technology. It uses a spam filter for this purpose.

How the spam filter works

The spam filter systematically checks all inbound and outbound e-mails for typical spam elements, such as links that are classed as unsolicited by recipients and therefore flagged as spam. All suspicious e-mails are sent to the spam folder. The spam filter also responds to global spam messages. In other words, if a large number of recipients flag an e-mail as spam, it will, in the future, be sent to the spam folder.

Report spam

If you receive a spam e-mail, you can flag it as spam to the provider of your e-mail service. In Bluewin, you do this by opening your webmail and selecting the icon () far right in the grey menu bar.

Also report the spam mail you received to the National Cyber Security Centre (NCSC) and spamreport@bluewin.ch.

However, please ensure that the mail in question really is unsolicited spam and not a regular newsletter. Otherwise, mail from genuine senders will, in the future, be diverted to other people's spam folders.
To stop receiving a regular newsletter, simply click the unsubscribe link at the foot of the e-mail.

Tips to prevent spam

Previously, a spam e-mail would be easy to identify from the many grammatical errors. This is no longer the case however. Nowadays, senders will often use the names of big companies and also copy their e-mail layouts. Follow the tips below to reduce your vulnerability to spam.

Frequently asked questions

If your e-mail is sent to the recipient’s spam folder, it has most likely been classed as potential spam by the e-mail provider. Make sure that your mail does not contain any links, signatures or images that could be flagged up as spam. 

If your e-mails are being classed as spam, try recreating the mail rather than editing it with the ‘reply’ or ‘forward’ functions. Otherwise, the previous e-mail communication will be included in the e-mail, making it more likely that your e-mail will contain a typical spam element.

If multiple recipients flag a genuine newsletter as spam, messages from this sender may be sent to the recipients’ spam folders.

Genuine newsletter senders, however, do include an unsubscribe link at the foot of the e-mail or an address to which requests to unsubscribe can be sent. Therefore, if you no longer wish to receive a newsletter, you should unsubscribe in this way.

If an e-mail is sent to your spam folder in error, you can mark it as “not spam” in Bluewin Webmail.
