I remember reading a blog post that I can't find that one company saw a massive uptick on email deliverability when they stop using .xyz and moved to a more standard one.

It makes some sense, .xyz are so cheap that I've bought mines for $1 so just buying a domain every day isn't outside the realms of possbility for spammers. Personally, I just use my .xyz domains for internal stuff where I still want things connected to the internet and available.
