So I noticed that a few of my emails never made it to public @gmail inboxes lately. Did some testing on a few personal gmails I own, and indeed, directly to spam, despite me clicking “This is not spam”. ALL and I mean ALL of my records are in order, SPF, DMARC, etc. The hosting provider confirmed all was well. After some deep digging, this is what I posted to help others on the google support page for this issue
" Update. This Helped me across multiple test Gmail accounts from spam to inbox. Be sure to have a valid .gmail account to be logged into when doing this. I even registered a brand new Gmail account to test, and it works. I guess Big G changed some things. [https://postmaster.google.com/]
