Starting this week, Yahoo is discontinuing Mail Classic. It’s requiring all Mail users to switch to the new version of Mail and accept a TOS/Privacy Policy update that lets it scan emails to “deliver product features, relevant advertising, and abuse protection”. You can opt out of the ads, but if you don’t want to be scanned, you have to ditch Yahoo Mail. Yahoo launched the new version of Mail in December, and announced the discontinuation of Classic back in April. However, it didn’t mention anything about the new terms of service and privacy policy until it just began sending Classic users an email about having to switch. In an aptly named Help center entry “Do I have to upgrade to the new Yahoo! Mail?”, the company explains: “Beginning the week of June 3, 2013, older versions of Yahoo! Mail (including Yahoo! Mail Classic) will no longer be available. After that, you can access your Yahoo! Mail only if you upgrade to the new version.”
