I noticed that a few years ago that Google had removed the very handy tool I used to filter all mail from "x" sender and I could select all and delete. I believe they did it on purpose because I think Google really doesn't want you to delete emails. They made it harder to delete emails in bulk.

I do subscribe to things I find interesting but other times they are emails from services I joing. I am now using Office 365 and am being able to keep it much cleaner. All my Newsletters go into a Newsletter folder and I have a Sweep rule to keep the 10 most recent and delete the rest. My inbox is way easier to manage now. And every year I move the corresponding emails from that year into a folder, like "2024" and go through it from time to time. It's being a bliss.

My two gmail accounts probably have way over 100k as I've more or less abandoned them. Google also made the total emails you have in the account less apparent too, I was up to 80k and suddenly my inbox had around "3,000" or so emails.
