Favorite Gmail Productivity tricks or apps?

Hi everyone,

I'm getting overwhelmed by the increased amount of emails/spams that are coming in (data breach?), and I've followed some YouTube videos. The issue is that it's either a bulk removal (i.e. by domain) or that it doesn't do a great job stopping emails from coming through.

The question to the community, what is your favorite way to manage inbox productivity and what were the results that you saw? Thanks!
