"Google's technology supports the Sky email service, and hence supports your @sky.com address. However, as a @sky.com email subscriber, your only relationship is with Sky. Please be reassured that Sky's Terms and Conditions and Privacy Notice apply and not Google's."
However, the thing that most people are taking issue with is how Google had their email address in the first place and what other uses the search giant might be putting those addresses to.
In a FAQ section on the erroneous email, Sky explained that Google had to have everyone's email address to provide email services to Sky, but the address was the only information the Chocolate Factory had and it hadn't shared it with anyone else.
A Virgin Media spokesperson said the same thing to The Register.
"All Google literally has is an email address that they provision to us," he said, adding that the firm needed to know these addresses so it could allocate storage to each address.
A Google spokesperson said that the Chocolate Factory was busy informing all its customers about its policy changes, including the administrators of enterprise organisations using Google Apps.
"If an enterprise organisation uses Google Apps to provide email to its own employees or customers, Google is contacting only the administrator at that organisation because it has a contract that defines how we handle and store their data," the spokesperson said.
