This is very similar to my approach that I've been refining over about 2 years, and especially so in the last year since I switched to Proton Mail (my business plan includes SimpleLogin). I finally achieved "inbox zero" a few weeks ago, which is something I scoffed at for the longest time as being useless and ridiculous, but it's actually quite nice.

Thanks for sharing.

I noted that I don't use email that much anymore. So my approach is to just archive everything once in a while.
