will email still be recuired for getting certs?

I don't think it ever was? I never gave my email address to LetsEncrypt but I'm also not using their official client.

Account registration is done by sending a public key to a certain API endpoint. The key will become associated with an account URL that looks like this: https://acme-v02.api.letsencrypt.org/acme/acct/4277968575

As far as I know. No.
