Instructions
Gather a new invoice or subscription bill from Hearst Magazines. This will come once a month, often with your magazine order.
Write "Cancel" at the top of the invoice. Make sure to write "Cancel" large and legibly.
Seal and stamp the invoice in its preaddressed envelope, and send it in the mail.
Sign in to your account on the Hearst Magazines periodical's website that you want to cancel, such as Cosmopolitan.com. You should have registered an account when you subscribed. If you have no account there, register one using your current email address.
Click on "Customer Service" at the top of the homepage. Click on "Cancel Subscription." Fill out the information required, and click "Send" when you are finished.
