@Gargron i like to have a compost folder on my email. the trash gets auto deleted after 1 month. the compost i manually look at after a while, and probably just wipe anything older than 2 years.

doing this for just less than 1 year now (perhaps as a necessity to get used after stop using gmail), and i expect to never need to read any of the compost emails again.

in gmail, i love to get random older than 10 years emails on my searches, and even replying to them eventually.
