20 million spam emails a day seems like an exaggeration. I get 10-20 a day to my GMail account, which I've had since the service started, and published online in multiple places.

Thanks for advice.

Changing email is my last option.

It's hard to change my address everywhere. What's worse, some website may send you a verify link to your old address before confirming a new address, and you need to click the link in, like 10min ~ 1hour. But I only get the confirm email days latter.
