Among the email brands under NetEase, 126 and 163 emails contain advertisements, and the content is like being carved out of the same "mold". There are no ads in yeah.net, and as for 188 and VIP, I'm not quite sure about them. Still, if we compare NetEase's ad-containing emails with QQ emails that don't have ads, then it's just like looking at others' shortcomings and thinking about my own advantages.
