Hi Cliff K, Go to: https://www.parallels.com/account/subscriptions/ (you would need to login to your Parallels account). Here you would need to check the 'Do not send me any messages' check box and save the changes if you indeed want to unsubscribe. Also, you may contact Parallels Customer Service at: https://www.parallels.com/support/request/ (support is free) at any time if you require anything else.
