Same exact issue, I could write the exact same thing word for word. I even "contacted Gmail support" 3 weeks ago to see if I could get anywhere on it, whatever void that message went to. Same "no data" in Postmaster Tools presumably because of my low volume, messages just variously go to spam in Gmail. The last one was a message to 9 Gmail recipients I had never contacted before which I guess was the issue.

It's been so frustrating that I'm contemplating going back to a provider, or at the very least paying for one of the "warmup services" mentioned here. If anyone has experience with those for non-business I'd love to read about it.
