Out of curiosity, where do you send the emails from? (Are the IP addresses from AWS/some other large provider? Or something else?) I've heard that the IP address block has something to do with getting marked as spam. I've checked everything on that list and it's all good, and I'm sending from IPv4. The really frustrating thing is that Google's own Postmaster Tools [0] doesn't want to tell me anything without "a sizable daily volume of email traffic (up to the order of hundreds)". If it doesn't have to do with the origin IP's neighborhood, my only other guess is that I don't have enough email volume, which seems like a catch-22... [0] https://gmail.com/postmaster/ |

At the time I allocate an IP address, it's was listed on DNSBL. I tried like 30times to get a good IP and gave up. I instead just allocate a new IP, wait a week. Started to send email to myself every 15minutes to a gmail address. Anytime it isn't showed up in Important, I go in to move it to important. If it showed up as spam, I marked it as not spam.
After 2-3 weeks doing that, The IP is no longer listed on any blacklist and I started to roll them out.
Don't worry too much about IP blacklist. They aren't super important to gmail. If an IP stopped sending spam, they will be removed from IP blacklist eventually. Give it a week.

I send about 8,000 emails per day and somehow that Postmaster Tools not reports anything at all. I would say
If you send me an email vinh@hanami.run I can tell you what you can do to avoid being flagged at spam. Happy to jump in a 1-1 chat https://calendly.com/vinh-hanami/15min to help you on that.
