Help Gmail has killed my personal email

So out of the blue, my extremely low traffic email has been blacklisted by google. It is not in DNSBL, end-to-end encryption is used when delivering mail, I have a http(s) on the same ip/domain with short bio, DKIM, DMARC, SPF, the works (that have been working since 2014) are set up, email tests that I can find on the internet are 10/10, never pwnd, but I still end up in spam. Postmaster tools are useless, as this is a personal email and the outgoing volume is too low to get any information from it. I've tried contacting gmail support, but you can probably guess how that went. Do I have to trade my privacy in forever now or does HN know some other tricks that could help me correspond with people on gmail?
