How to get out of gmail spam?

Question

postfix

Hello everyone, I created my own server, set up sending emails, everything works fine, only emails constantly end up in spam, there is no spam in messages or something else, I only send to my accounts, I always mark Not Spam. I still end up in spam.
I passed the SPF test

ARC-Authentication-Results: i=1; mx.google.com;
       spf=pass (google.com: domain of ... designates .... as permitted sender) smtp.mailfrom=....

The server has just been created, I also added both DKIM and DMARC to the DNS records, and configured Postfix according to the tutorial.
What else can I do to prevent Google from sending emails to spam?

Google is very fond of MTA-STS.
Sometimes its implementation helps to "get out of gmail spam".

It was not necessary to organize mail on the server. Try moving your mail to a google business account.
