I use single-purpose email addresses and so feel free to sign up for the mailing lists of things I’m specifically interested in. If I get an email from anyone else then that email address gets scrapped and I know I can’t trust that entity anymore.
If the emails I’m getting aren’t occasionally interesting to me, I unsub. But if an artist is making cool things and sharing them then those emails are worth reading. If a place I want to buy some stuff from is having a sale, that’s worth knowing (and if I might buy from there, I filter their emails so they aren’t in my inbox but are available and I can grab a coupon code from a recent email when I spontaneously decide to buy something). If new features are coming to a service I already use, then that kinda is “news” for me.
