Hello,
Unfortunately, even if everything is correct, as I see, PTR, SPF, DKIM, DMARC, etc, your IP has a poor reputation:

The only thing you can do is use a smart relay host to send your emails, you can see the steps in how to configure here:

Of course you can choose the provider you like, and as you can imagine you will need to edit SPF, DKIM and others.

Best regards
