Around the beginning of every month I get a marketing e-mail from email@example.com telling me about all the TV channels they want me to buy. At the bottom of each e-mail is a link to unsubscribe from it. I have visited it on multiple occasions but the marketing e-mails don't stop. I called Shaw support and got someone to manually unsubscribe me but I'm still getting them.
Beyond cancelling all my Shaw services, what does it take to stop getting this spam?
