In every email that GFI sends to you, there is an unsubscribe hyperlink, which you can click if you wish to opt out of receiving receiving email communications from us. The hyperlink will direct you to our website, where you can enter the email address that you no longer wish to receive GFI emails. One last confirmation email will then be sent to the email address you designate. Confirm that you do indeed wish to stop emails from GFI and your email address will be unsubscribed.
Alternatively, you can email GFI at email@example.com with your request, stating Unsubscribe in the header and the email addresses you wish to stop receiving GFI emails. This address will then be removed from any subscriptions shortly.
