Unfortunately a lot of the issues with deliverability comes from how many emails your IP have successfully sent in the past x number of hours. When I ran larger email lists I had absolutely no issues in delivering to the top providers. Its only since the lists moved to a new home I had deliverability issues.
That's insightful, thank you. I suppose their argument would be that a substantial volume of messages is needed to collect strong evidence of a server's maintaining appropriate sending policies. It may be worth noting that Microsoft 365 is now sending DMARC aggregate reports regularly; other large providers were already doing so.
