Everything has a cost, especially in the realm of online services. It used to be a pretty common practice for providers of 'free' email services to scan their user's messages for data that'd be valuable to advertisers. The data got sold to keep the email provider's lights on, with in-browser advertising filling in the financial gaps. Most email providers abandoned the practice, years ago: they were amazed to find that it pissed off their users. Yahoo's parent company, Oath, however, is getting back on this particular brand of bullshit.

Yahoo’s owner, Oath, is in talks with advertisers to provide a service that would analyze over 200 million Yahoo Mail inboxes for consumer data, sources told WSJ. Oath did not immediately respond to a request for comment.
Oath confirmed to the WSJ that it performs email scannings and said that it only scans promotional emails, usually from retailers. Users have the ability to opt out, it said. Oath’s argument is that email is an expensive system, and people can’t expect a free service without some value exchanged.
