Thanks for the message. The easiest way to manage subscriptions (including canceling) is to go to your settings page - https://seekingalpha.com/account/subscriptions_settings. We need to make that easier to find, but you can get to it by clicking on your profile image in the top right of the website; a drop down menu will show up, and settings will be an option.
Separately, you can email us at email@example.com to cancel.
Please let us know if you'd like us to do that for you or if you have any other questions.
