> Gmail and Yahoo are getting serious about spam monitoring and senders will need to ensure they’re keeping below a set spam rate threshold.

Does anyone know what this sentence means? Is this “the user said this is spam”, or “the gmail spam filter false positives 10% of the time; don’t be part of the 10%, or it’ll permaban you”?

Gmail postmaster tools says, "This dashboard shows the percentage of user-reported spam vs emails that were sent to the inbox for active users. Emails delivered directly to the spam folder are not included in the spam rate calculation. Only emails authenticated by DKIM are eligible for spam-rate calculation."

The threshold for the number defined above is 0.3%; that's the point where Gmail starts penalizing the sender by putting their emails in spam folders.

Oh, so if 0.3% of people subscribe to a mailing list, then mark it as spam (instead of unsubscribing), then it goes to my spam folder?

That explains why I had to immediately disable gmail's spam filter.

In my experience, it means nothing. Most of the spam I get to my Gmail account comes from other Gmail users using Gmail, and I don't believe Google will do anything to hold themselves accountable.
