Is this email really from Coinbase?

Emails from Coinbase will always have the coinbase.com domain name at the end of them. For example  emails from support@coinbase.com, contact@coinbase.com, no-reply@coinbase.com, and any other email from the @coinbase.com domain can be trusted

We also send emails from Coinbase sub-domains. For example a message from  contact@updates.coinbase.com are valid. Note that the email address ends in .coinbase.com.

Regardless of sub-domain, we cryptographically sign all of our emails using DKIM and protect our domain against unsigned email with DMARC.
