This will sound facetious, but I mean it sincerely. Change email provider. I was an original "invite only" user of GMail. Eventually, I got so sick of Google's complete u-turn on their original philosophy that I changed, despite the cost in time and effort that decision entailed. It's worth it. But I will recommend you choose providers carefully. If you're not paying for it in some way (e.g. Fastmail), be concerned. Also, the ability to use your own domain is a huge boon (you'll never have to go through the excessive email-change pain again).
