Does anyone else feel like their inbox has become their job?

Lately I’ve realized I’m not spending most of my day doing the work I get paid for. I’m managing email, follow-ups, scheduling, and loose ends around that work.
It’s not even the time. It’s the constant background stress of “did I miss something important?”
Curious how other freelancers and solo operators deal with this.
I ended up building a personal assistant for myself to own inbox-derived work so nothing important slips, but I’m more interested in how others approach the problem.
