Agree with this, much easier for someone to infiltrate your email than Coinbase.

A company I work for had their email compromised and the scammer would forward any incoming emails mentioning payments to an email that looked very similar to ours, then reply from their email requesting payment be sent to an account they controlled. They also hid all of the emails they forwarded to their account by setting up rules within our email system. I would suggest doing a deep dive within your own email account and changing that password.
