> Report it to google, and make the world a better place.
That's line is not gonna work on me. Google is a trillion dollar company that only cares about its bottom line, not a public good. They can sort it out themselves.
I have better things to do with my time than do Google spam team's job for free by reporting each spam email I receive manually.
I've had good responses from most places. An Eastern European domain registrar has revoked several scammer domains after my notifications. Some ISPs are a waste of time to send reports to, e.g., a few in E. Europe, and Colo Crossing. But, it is usually worth it to report abuse. I have an emeritus email address from a former employer where I made it my project since the pandemic to report all spam/scam mail received to that address. I cannot state that this is the reason nor even the main reason, but the volume of spam to that address has gone from a firehose to a single spam/scam message every 1-3 weeks.
Are you kidding? The Goo has never paid any attention to the victims of spam emanating from gmail accounts.

But, first check the first received header that was added by your mail provider's servers to make sure the spam really is coming from gmail's servers-- oldest received headers are at the bottom, newer as you go up (e.g., view message source, view headers, or some such option in your client; look for received: from...).
Add a short blurb at the top of your message about spam received from their domain, include the message with full headers as text at the end of the email (some clients like MS outlook break mail, so this may be the only way the recipient will be able to view the headers. Also attach the original spam message as an attachment (this will provide something useful to the recipient for most non-Microsoft mail clients).
