I know I speak for everyone in saying how delighted we are that the spam email we never signed up for and can't unsubscribe from (and never open) will be better looking on our phones.
...if you're getting spam, then you signed up for it. I know this because I use gmail and don't get spam, or at least if I do it's always automatically filtered so I never ever see it.
Maybe it's more a problem with how you use email if that's an issue you have.
Sorry but it's not so simple. I have two GMail accounts. One I use primarily as work/tech email list related stuff and there I get close to zero spam. The other is connected to a Youtube channel where I used to post gaming content and in general I use the second GMail account for gaming-related purposes. While it has improved somewhat recently for quite a while I was getting around 10-20 spam emails a day. Perhaps you can argue that I signed up for the spam by giving my email address to others. But the spam was clearly unrelated to anything I had ever requested.
