All sent and received e-mails in Gmail will be analyzed, says Google

Google added a paragraph to its terms of service as of Monday to tell customers that, yes, it does scan e-mail content for advertising and customized search results, among other reasons. The change comes as Google undergoes a lawsuit over its e-mail scanning, with the plaintiffs complaining that Google violated their privacy.

E-mail users brought the lawsuit against Google in 2013, alleging that the company was violating wiretapping laws by scanning the content of e-mails. The plaintiffs' complaints vary, but some of the cases include people who sent their e-mails to Gmail users from non-Gmail accounts and nonetheless had their content scanned. They argue that since they didn't use Gmail, they didn't consent to the scanning.
