In my experience, everyone got their act together except Google. I also used to receive massive amounts of spam from Azure and Sendgrid but this eventually stopped. Now 80% of the spam I receive is from the Google network, mainly Google Cloud.

I remember a bunch of spam and fishing emails from weird Outlook addresses. Don't remember any from Google.

Why do you interpret that as everyone except Google getting their act together?

The obvious (and correct) explanation is deliverability. Spammers send from Google services because they can inbox, they don’t send from other services because those services will not inbox successfully.

For me outlook is just as bad as google in terms of the spam that gets through my spam filters, as neither of them care much about abuse reports.

You mean you receive unsigned email from a VPS in Google Cloud?

Add Mailchimp in there as well. I have never gotten an email from someone using Mailchimp that was not spam.

Although they does have proper abuse policies and do take action against spammers. I don't get any spam from them (except perhaps the very occasional one), and I know businesses that use mailchimp and similar services for valid marketing (to previous customers). Just looking through my received mailbox, I see many legitimate emails from mailchimp.

I'm not denying that they are sometimes used by spammers, but they are definitely a legitimate operation that takes action against spammers if you report them.

Many of my consciously subscribed-to newsletters use Mailchimp, such as record shops and labels.

They're also one of the mail services I have a better impression of given their responses to my reports.

Yeah, Salesforce clearly has some kind of whitelisting at Gmail. I get so much nonsense from that domain.
