What else do you want from that email? You got a new subscriber. There's their name. Why change the layout just for the sake of change? Surely there are people having rules or automations tied to them, why brake them? Just for funsies?
Why change for the sake of change? Because marketing analytics says they need to be the face of new-new. Why risk breaking automation? Because that's a you-problem. Google does not care about you, the user. They want you, the ad target. Things break all the time for meaningless changes
I wish youtubes LAYOUT wouldn't considerably change.
I just got the new layout, where comments are on the right, and suggested videos are this big ugly massive blocks that fit 2 per screen, and you need to scroll to see more.
The whole thing is ass, and I watch less youtube because I don't want to be bothered.
What was even the purpose of that button? Surely if you get spam, you don't report that to the spammer, you use the mechanism provided by your email service.
It was to report a bug in their email system involving unwanted emails (for instance if they continued sending you email after you unsubscribed from it).
I've heard that if you want to sit through their Copyright violation series, they still use Happy Tree Friends videos they commissioned. At least I saw some show that about two years ago
