Or migrate to Fastmail. It's painful but doable if you have a gmail address (redirect all mail to your new address with an out-of-office automatic reply about the change). While you're at it, get your own domain (through Fastmail or others) so this never happens again (https://www.fastmail.help/hc/en-us/articles/360058753394-Cus...). I was lucky enough to start out on Gmail with my own domain back when that was free, and it meant that I could migrate to Fastmail without anyone even noticing.

No affiliation with them, just very happy I made the switch.
