Google hates this trick: make a second gmail account and auto-forward your significant mail there (skip newsletters, broadcasts, etc). And delete mail with unneeded attachments, which is where I use most of my disk space. (“Sis, did you really need to send me FIVE vids of my nephew doing the Hokey Pokey?”). When all mail is completely forwarded, delete the original mail at will. When the new acct is full, create another account.

You can do this forever. Each account gets it’s own quota. You’ll have to recall which acct has which mail so name the accounts with the year you created it, ex, Harvey.Cohen.2021
