I unsubscribe aggressively. I keep my inbox well maintained, but that's still not the feature I'm talking about.
My work sends me several shipping notifications a day, but they are not priorities. They are emails to be reviewed later in the day. I don't want push notifications for them. I don't want them in my primary inbox. Gmail (without me telling it to) puts them in the "updates" tab.
Same for the promotional emails that come in. They go in "promotions".
If I get a 2FA email or an update on a social website they are sorted in the "social" tab without my having to set anything up.
This is extraordinarily helpful for managing my email, and it is absent in every client I have tried.
Shouldn't updates go to "social", and 2fa - to inbox?
Exactly. I do unsubscribe--perhaps not as aggressively as I should--but there's a ton of stuff I may want to be aware of that I don't want polluting my primary mailbox. Sometimes I even shift them to my primary tab but, in general, I'm happy with keeping my primary to stuff that I generally do mostly care about and have a few other categories I care about to varying degrees.
